Signs of Cataracts: What to Look For and When to Seek Help

May 27, 2025/in Cataracts, General Optometry /by 20North

Quick Take: Cataracts can cause:

- Cloudy vision
- Increased light sensitivity
- Faded colors
- Problems seeing at night

These cataract symptoms often develop slowly, and recognizing them early can help you seek appropriate treatment before your daily activities are affected.

Cataracts are one of the most common eye conditions, especially among people over 60. They occur when the eye’s natural lens becomes cloudy, similar to looking through a foggy window. While age-related cataracts develop gradually, knowing the early signs helps you maintain clear vision and quality of life.

In this blog, you’ll learn:

What cataracts are and why they form
Common signs like cloudy vision and light sensitivity
When to see an eye doctor
Treatment options, including cataract surgery
How to protect your vision over time

What Are Cataracts?

Cataracts form when proteins in the eye’s lens clump together, creating a clouded lens that scatters light and reduces visual clarity. This buildup leads to vision problems like blurry vision, glare, and difficulty reading or driving.

The lens sits behind your iris (the colored part of your eye) and works much like a camera lens, focusing light onto the retina at the back of your eye. A clear lens allows for sharp images on your retina, but when a cataract clouds the lens, your vision becomes blurred, similar to looking through a dirty windshield or a fogged-up window.

Types of Cataracts

There are several types of cataracts, each affecting different parts of the lens:

Nuclear cataract: Forms in the center of the lens and is most commonly related to aging. These cataracts often temporarily improve near vision before overall vision deteriorates.
Cortical cataract: Starts at the edges of the lens and gradually moves inward. These appear as wedge-shaped cloudy areas that extend from the outside edge toward the center, often resembling spokes on a wheel.
Posterior subcapsular cataract: Develops at the back of the lens, often leading to difficulty with bright light and night vision. These tend to progress faster than other types and frequently affect people with diabetes or those taking steroid medications.
Congenital cataract: Present at birth or during childhood (also known as pediatric cataracts). These can be hereditary or result from an infection during pregnancy.

What Causes Cataracts?

Cataracts can result from a range of factors, including:

Age, especially after 60
Medical conditions like diabetes or macular degeneration
Long-term exposure to bright sunlight or toxic substances
Smoking or alcohol use
Long-term steroid use
Previous eye injuries, retinal detachment, or eye surgery
Family history of cataracts

While aging is the primary cause, research suggests that oxidative stress plays a significant role in cataract development. This happens when unstable molecules (free radicals) attack and harm the proteins in the eye’s lens. This damage accumulates over a lifetime, which explains why cataracts become more common as we age.

Early Signs of Cataracts

In the early stages, cataracts may not be obvious, but subtle vision changes often appear.

Common early symptoms include:

Cloudy vision or a sense that things look dim or hazy
Difficulty seeing at night or in low-light settings
Sensitivity to bright light and glare from headlights or sunlight
Seeing halos around light sources
Double vision in one eye
Colors appearing faded or yellowish
Needing more light to read or complete close-up tasks
Frequent changes to your lens prescription or contact lenses

These symptoms can come on slowly, which is why regular eye exams are essential.

Many people describe early cataract symptoms as similar to looking through a dirty car windshield or a piece of wax paper. You might find yourself cleaning your glasses frequently, thinking they’re dirty, when the problem is actually with your eye’s lens.

When Cataracts Get Worse

As the cataract progresses, the symptoms become more disruptive to your daily activities. You may notice:

Increasingly blurry or cloudy vision
Trouble distinguishing colors, especially blues and purples
Heightened light sensitivity and glare from bright sunlight
A white or yellow tint in the pupil (a possible sign of a mature cataract)
Temporary improvement in near vision (“second sight”), followed by worsening overall clarity

These are signs of an advanced cataract, and you should consult an eye doctor promptly.

As cataracts mature, the lens may turn a brownish-yellow color, distorting your color perception. Many patients describe this as viewing the world through a sepia-toned filter. This color shift can make it difficult to distinguish between certain hues, particularly in the blue-purple spectrum.

How Cataracts Impact Daily Life

Cataracts can affect your ability to function comfortably at home, work, and on the road.

You might experience:

Driving difficulties – especially with night vision or glare from headlights
Reading problems – needing more light or magnification to see small print
Trouble recognizing faces from a distance
Difficulty with tasks that require visual detail, like sewing or cooking

If vision loss starts to interfere with normal routines, it’s time to consider your treatment options.

The impact of cataracts often extends beyond just vision problems. Many people experience increased anxiety, particularly around driving at night or in unfamiliar places. Social isolation can occur when individuals begin avoiding activities they once enjoyed because of vision difficulties. Studies show that untreated cataracts significantly increase the risk of falls and accidents, especially in older adults.

When to See an Eye Doctor

You should schedule an eye exam if:

You notice vision changes that make it harder to perform everyday tasks
Colors appear dull or yellowed
You’ve had multiple updates to your glasses or contact lenses
Glare or halos interfere with driving or reading
Any of the above symptoms of cataracts are affecting your comfort or independence

Recommended exam schedule:

Age	Recommended Exam Frequency
40-54	Every 2-4 years
55-64	Every 1-3 years
65+	Every 1-2 years
Patients with underlying conditions (diabetes, family history)	Annually

Diagnosing Cataracts

To confirm a cataract diagnosis, your eye doctor may:

Perform a visual acuity test
Use a slit-lamp microscope to examine the clouded lens
Dilate your pupils to inspect the retina
Test how you respond to glare and how well you perceive contrast
Evaluate color vision and depth perception

These evaluations help determine the best course of treatment, including whether surgery is needed.

During a comprehensive eye exam, your doctor will also check for other eye conditions that may coexist with cataracts, such as glaucoma or age-related macular degeneration. This thorough approach ensures that all potential vision threats are identified and addressed.

Cataract Treatment Options

Non-Surgical Management

In mild cases, especially during the early stages, symptoms can often be managed through:

Updated lens prescriptions
Anti-glare coatings on glasses
Brighter lighting at home
Use of magnifiers or visual aids

Cataract Surgery

If the cataract significantly impacts your vision and daily activities, cataract surgery is recommended. This involves removing the cloudy lens and replacing it with an artificial lens, also known as an intraocular lens (IOL).

Types of IOLs include:

Monofocal lenses – Set to focus at one distance (usually for distance vision)
Multifocal lenses – Allow both near and far focusing
Toric lenses – Correct astigmatism during surgery
Light – Adjustable Lenses

Most cataract patients report noticeable improvement in clear vision within a few days, with full recovery in 4–6 weeks.

Cataract surgery is one of the most commonly performed surgical procedures worldwide, with a success rate of over 95%. The procedure typically takes less than 30 minutes and is performed on an outpatient basis, meaning you can go home the same day. Modern techniques use ultrasound (phacoemulsification) to break up the cloudy lens before removal, requiring only tiny incisions that often heal without stitches.

Preventing Cataracts or Delaying Their Progression

While not all cataracts can be prevented, you can lower your risk by protecting your eyes and maintaining overall health:

Wear UV-blocking sunglasses in bright conditions
Stop smoking
Control diabetes and other chronic illnesses
Eat a balanced diet rich in leafy greens and antioxidants
Follow regular exam schedules recommended by the National Eye Institute

Certain nutrients may help protect against cataract formation. Vitamins C and E, lutein, zeaxanthin, and omega-3 fatty acids have shown promise in some studies. A diet rich in colorful fruits and vegetables provides these protective compounds naturally.

Taking Action: Restoring Your Clear Vision

Cataracts are a common part of aging, but that doesn’t mean you have to live with cloudy vision or limited night vision. Recognizing the signs of cataracts early and discussing your options with an eye doctor can help you preserve your vision and quality of life.

At Visionary Eye Doctors in Maryland and Washington, DC, we’ve helped thousands of patients regain clear vision through expert diagnosis and advanced cataract surgery using the latest intraocular lens technology.

Is Glaucoma Hereditary? Understanding Your Family Risk

May 27, 2025/in General Optometry, Glaucoma /by 20North

The short answer: Yes, glaucoma has a strong genetic component. If you have a family member with glaucoma, your risk increases significantly..

Glaucoma affects millions of people worldwide, damaging the optic nerve through increased intraocular pressure. This pressure builds when the eye’s drainage system doesn’t allow fluid (aqueous humor) to flow out properly. What many don’t realize is that by the time noticeable symptoms appear, permanent vision loss may have already begun.

But what exactly does this mean for you and your eye health? Let’s explore the hereditary nature of glaucoma, what it means for families, and the steps you can take to protect your vision

The Genetic Risk: By the Numbers

Family history stands as one of the most significant risk factors for developing glaucoma. Primary open-angle glaucoma, the most common type, has a strong genetic component that can dramatically increase your chances of experiencing optic nerve damage and potential vision loss.

When doctors know glaucoma runs in your family, they can implement more frequent screening and earlier interventions. This is crucial since intraocular pressure can damage the optic nerve without noticeable symptoms until permanent vision loss has already begun.

Types of Glaucoma

Not all types of glaucoma have the same genetic component. Here’s how heredity influences different forms:

Primary Open-Angle Glaucoma (POAG)

Primary open-angle glaucoma shows the strongest genetic connection. It’s the most common type, accounting for approximately 90% of all glaucoma cases in Western countries. Research has identified several specific genes linked to POAG risk, including:

MYOC gene – Mutations here are found in 3-5% of POAG patients
OPTN gene – Associated with normal tension glaucoma
WDR36 gene – Linked to various forms of glaucoma

These genetic variations affect how eye pressure is regulated and how the optic nerve responds to stress. While having these genetic risk factors doesn’t guarantee you’ll develop glaucoma, it does significantly increase your likelihood.

Angle-Closure Glaucoma

Primary angle-closure glaucoma also has genetic components, particularly in certain ethnic populations. People of Asian descent have anatomical eye characteristics that can be inherited and increase the risk for this type, which can cause rapid pressure buildup and require immediate medical attention.

Congenital Glaucoma

Primary congenital glaucoma, present at birth or developing in early childhood, has the clearest inheritance pattern. This rare form is linked to mutations in the CYP1B1 gene, which affects how the eye’s drainage system develops. In many cases, both parents must carry the defective gene for a child to develop this type.

Beyond Genes: Other Risk Factors For Developing Glaucoma

While genetic predisposition creates your baseline risk, several other factors influence whether someone with a family history actually develops glaucoma:

Age

Age remains a significant risk factor for most types of glaucoma:

Under 40: Lower risk (except with strong genetic factors)
Ages 40-60: Moderate and increasing risk
Over 60: Highest risk, with rates four times higher than younger populations

For those with a family history, the risk curve shifts earlier, with symptoms sometimes appearing 10-15 years sooner than in the general population.

Other Medical Conditions

Several health conditions can interact with genetic factors to further increase glaucoma risk:

Diabetes doubles the chance of developing glaucoma and can accelerate progression
Hypertension affects blood flow to the optic nerve
Heart disease may compromise oxygen delivery to eye tissues
Sleep apnea has been linked to normal tension glaucoma
Managing these conditions becomes especially important for those with a family history of glaucoma.

Environmental Factors and Lifestyle

Even with genetic risk factors, lifestyle choices can help reduce your overall risk:

Regular exercise can help maintain healthy eye pressure levels
Smoking cessation improves blood vessel health and oxygen flow
Eye protection prevents injuries that could trigger secondary glaucoma
Limited steroid use (when medically appropriate) reduces medication-induced pressure increases
Proper hydration supports overall eye health

Family History: What You Need to Know and Share

Understanding your family’s eye health history can help you and your eye doctors be proactive when it comes to glaucoma development. Consider these questions:

Has anyone in your immediate family been diagnosed with glaucoma?
At what age did their glaucoma develop?
What type of glaucoma do they have?
How severe is their condition?
What treatments have they needed?

Create a basic family eye health tree extending to grandparents, parents, siblings, and children. Share this information with your eye doctor to help them determine your risk level and appropriate screening schedule.

Testing and Early Detection: Your Prevention Strategy

For those with a family history of glaucoma, early and regular screening becomes vital. While genetic testing can provide additional information in some cases, comprehensive eye exams remain the primary tool for detection.

When to Start Regular Screenings

If glaucoma runs in your family, follow these guidelines:

Age Group	Family History	Recommended Screening Frequency
Under 40	Yes	Every 1-2 years
40-54	Yes	Annually
55+	Yes	Every 6-12 months
Any Age	No	Every 2-4 years (more frequently after 40)

What to Expect During a Comprehensive Eye Exam

During a comprehensive eye exam for glaucoma, your doctor will perform several key tests to assess your eye health. The process begins with tonometry to measure intraocular pressure, followed by visual field testing to check your peripheral vision for any early signs of vision loss. Your doctor will then conduct a dilated eye examination, which allows for a thorough inspection of the optic nerve to detect any signs of optic nerve damage.

For more detailed evaluation, optical coherence tomography (OCT) creates precise images of your optic nerve structure, helping identify subtle changes that might indicate glaucoma. Finally, pachymetry measures your corneal thickness, as thinner corneas can increase glaucoma risk. These non-invasive tests provide a complete picture of your eye health, making regular eye exams essential for early detection and preventing permanent vision loss.

Genetic Testing Options

For families with strong patterns of glaucoma, genetic testing offers valuable insights into your risk profile. This testing benefits those with multiple affected family members, early-onset glaucoma, or rare disease forms by identifying specific mutations and determining personal risk levels. While the process requires just a simple blood or saliva sample, it’s important to note that not all genetic factors for glaucoma are known yet. Discuss with your eye doctor whether this testing would be beneficial for your specific situation.

Proactive Steps to Minimize Glaucoma Risks

If your family history puts you at higher risk for glaucoma, taking proactive steps becomes essential:

Monitor Your Eye Health

Keep regular appointments with your eye doctor
Know your baseline numbers for eye pressure and visual field tests
Watch for warning signs between examinations

Know the Warning Signs

While early-stage glaucoma often lacks noticeable symptoms, be alert for:

Gradual loss of peripheral vision
Seeing halos around lights
Eye pain or severe headaches (especially with closed-angle glaucoma)
Redness in the eye
Vision changes that don’t improve

Contact your eye doctor immediately if you experience sudden vision changes or eye pain, as these could indicate acute angle-closure glaucoma requiring urgent care.

Treatment Options: Early Intervention Matters

For those diagnosed with glaucoma, treatment options typically include:

Eye drops to lower intraocular pressure
Laser treatments to improve drainage
Minimally invasive glaucoma surgeries (MIGS)
Traditional surgeries like trabeculectomy for advanced cases

The key is early diagnosis, which allows for less invasive treatments and better vision preservation. This is particularly important for those with genetic risk factors, who may see more rapid progression without intervention.

Knowledge is Protection

Understanding the genetic component of glaucoma empowers you to take control of your eye health. While you can’t change your genetic makeup, knowing your family history allows you to work closely with eye care professionals to detect and manage glaucoma early, when it matters most.

At Visionary Eye Doctors, we specialize in comprehensive glaucoma care, from advanced diagnostics to the latest treatment options. We encourage everyone, especially those with a family history of glaucoma, to schedule regular comprehensive eye exams.

Does Cataract Surgery Correct Vision?

May 6, 2025/in Cataracts, General Optometry /by 20North

The Short Answer: Cataract surgery can correct vision by replacing your eye’s natural lens with an artificial intraocular lens. Modern cataract surgery offers various premium IOL options that can improve both your cataract-related vision problems and other vision issues like nearsightedness or farsightedness.

While the quick answer is yes, there’s more to the story. From how cataracts affect your sight to the types of surgeries and lenses available, understanding your options can help you make the best decision for your eyes and lifestyle. Keep reading to get a full picture of what cataract surgery involves—and how it can restore your clarity.

Understanding Cataracts and Vision Impact

What Are Cataracts?

A cataract occurs when the eye’s natural lens, which normally focuses light onto the retina for clear vision, becomes cloudy. This cloudiness happens when proteins in the lens begin to break down and change their structure, blocking light from passing properly through the eye. The result is like looking through a foggy window, making daily life activities more difficult.

People with vision problems from cataracts often notice their vision becoming increasingly blurry over time. Common signs include:

Frequent changes in glasses prescription
Seeing halos around bright lights, especially while driving at night
Increased glare sensitivity
Difficulty reading in dim lighting
Colors appearing faded or yellowish

Causes and Risk Factors

Age stands as the leading cause of cataracts, with most older adults developing them as a natural part of getting older. While some people may notice changes in their 50s, cataract surgery becomes most common for those in their 70s.

According to the National Eye Institute, several other factors can increase your risk of developing cataracts:

Extended exposure to UV light and sunlight
Eye injuries or trauma
Use of certain medications, particularly steroids
Medical conditions like diabetes
Some people are born with cataracts, though this is rare

Surgery becomes necessary when cataracts begin to interfere with daily activities and quality of life. This typically happens when updating your glasses prescription no longer helps improve your vision, or when vision changes occur rapidly within a year. At this point, the only effective treatment is surgical removal of the clouded lens and replacement with an artificial intraocular lens.

Types of Cataract Surgery

Traditional Surgery

Technology Overview:

Uses phacoemulsification (ultrasound technology)

Key Steps:

Eye surgeon makes a tiny incision in the eye
Ultrasound breaks up the clouded lens into small pieces
Lens fragments are carefully removed through the incision
Artificial intraocular lens (IOL) is placed into the lens capsule

Key Benefits:

Remains one of the most frequently performed surgical procedures worldwide
Well-established procedure with extensive safety record
Effective removal of cataracts to improve vision
Compatible with various types of intraocular lenses
Covered by most insurance plans

Patient Considerations:

Outpatient procedure typically takes about 15-20 minutes
Patients return home the same day
Vision improvement is noticeable by the next day
Complete healing takes about a month while using prescribed eye drops

Laser-Assisted Surgery

Technology Overview:

Uses femtosecond laser (produces ultra-quick pulses in trillionths of a second)
Replaces several steps traditionally performed by hand

Key Benefits:

Creates precise incisions
Softens the cataract for easier removal
Provides accuracy for premium IOL placement (multifocal or extended depth of focus lenses)
Can correct astigmatism during the procedure with precise corneal incisions

Patient Considerations:

Not required for all patients
Often recommended for those choosing premium lenses
Beneficial for certain eye conditions
Recovery timeline similar to traditional surgery
May provide more predictable results for specific cases

Both surgical options are safe and effective. The choice between them often depends on factors like:

- Lens choice
- Presence of astigmatism
- Insurance coverage.

As with any medical procedure, your eye doctor will help determine which approach best suits your specific needs and vision goals.

Lens Options and Vision Correction

Every type of cataract surgery involves replacing your cloudy natural lens with an artificial intraocular lens (IOL). There are several IOL options available, each offering different benefits depending on your lifestyle, vision needs, and budget. Understanding these options will help you make an informed decision with your ophthalmologist about which lens is right for you.

Standard Monofocal Lenses

Monofocal IOLs:

Monofocal lenses represent the most common choice in cataract surgery. These artificial intraocular lenses focus light at one specific distance, typically set for clear distance vision. Patients can select whether they want their vision optimized for distance, medium-range, or close-up activities. Most people opt for distance vision correction and use reading glasses for close work.

Two Different Monofocal Lens Types:

For those interested in a different approach, monovision setup allows one eye to focus on distant objects while the other handles near vision, though this arrangement isn’t suitable for everyone.

Advanced Lens Options

Modern cataract surgery offers several sophisticated lens choices.

Light Adjustable Lenses (Latest Technology)

The Light Adjustable Lens (LAL) is a type of intraocular lens, or IOL, that is used to replace your natural lens during cataract surgery. It is the only IOL available that is customizable after cataract surgery. These lenses are made of a photosensitive material that can be changed after cataract surgery to optimize your vision.

Multifocal Lenses:

Multifocal lenses contain multiple focusing zones, similar to bifocal glasses, allowing clear vision at various distances. While these premium IOLs might eliminate the need for glasses completely, some patients notice halos or bright lights.

Extended Depth of Focus Lenses:

Extended depth of focus (EDOF) lenses provide a single, stretched focusing zone for better distance and intermediate vision, with fewer visual disturbances than multifocal options. For patients with astigmatism, toric lenses offer built-in correction and work with any lens platform.

Expected Outcomes

Most patients notice vision improvement by the day after surgery
The eye needs about a month to heal fully, with eye drops helping prevent infection and support healing
Initial mild irritation or itching typically subsides after the first night
Patients can usually return to work within two days
Heavy lifting or bending should be avoided during recovery
Final vision results depend on the chosen lens type:
- Monofocal lens users often need reading glasses
- Advanced lens options may reduce or eliminate dependence on glasses

Having realistic expectations about your selected lens type helps ensure satisfaction with the results.

Recovery and Long-term Results

Immediate Post-Surgery Period

The first 24-48 hours after cataract surgery are mild and straightforward for most cataract patients. Most people notice some itching or light irritation during the first night, but the outpatient procedure causes minimal discomfort. You’ll wear a protective shield over your eye for the first day, then only at night for a week afterward.

Your eye doctor will give you specific instructions about eye drops, which you’ll need to use for about a month to help with healing and prevent infection. During this initial period, you should avoid heavy lifting or bending down. Most people can return to daily life within one or two days, though you’ll need to stick to light activities.

Vision Stabilization

Vision improvement often begins the day after surgery. While many patients see better almost immediately, your vision may be blurry vision and fluctuate for several days as your eye heals. Full vision stabilization typically occurs within a few weeks, though this can vary among patients.

Your eye doctor will schedule follow-up appointments to monitor your healing and vision progress. The first check-up usually happens the day after surgery, with additional visits during the first month. These visits help make sure your eye is healing properly and your new lens is functioning as intended.

Long-term Benefits

Once your eye fully heals, you can expect clear vision that remains stable. Many patients report better vision than they had before their cloudy lens developed. Your artificial lens won’t develop cataracts and should last for the rest of your life.

The improvements in daily life can be remarkable. Activities are made easier, including:

Driving (especially at night)
Reading
Watching TV
Using digital devices

Many patients find they need fewer vision aids than before surgery. Depending on the type of intraocular lens chosen, some people can reduce or eliminate their dependence on glasses, though reading glasses might still be needed for close-up tasks.

Conclusion

Modern cataract surgery is a remarkable advancement that does much more than just remove cloudy lenses. Today’s surgical options can meaningfully correct vision through precise techniques and premium IOLs. The procedure allows most cataract patients to see more clearly within days, with options ranging from monofocal lenses to advanced multifocal lenses that can reduce dependence on glasses.

When considering cataract surgery, consider:

Your lifestyle needs
Your specific vision goals
Solutions available for:
- Distance vision (driving)
- Reading vision
- Astigmatism correction

Can Dry Eyes Cause Blurry Vision?

May 6, 2025/in Dry Eyes, General Optometry /by 20North

The Short Answer: Yes, dry eyes can cause blurry vision. When your eyes lack proper lubrication from tears, the surface of your eye becomes irregular and affects how light enters your eye, resulting in unclear vision.

Your eyes rely on a consistent layer of tears to maintain sharp, clear vision. Think of tears as a smooth window that light must pass through before reaching the sensitive parts of your eye. When that window becomes disrupted due to dry eyes, your vision can become temporarily blurred or distorted.

According to the National Eye Institute, dry eye affects millions of Americans, with nearly 16 million adults diagnosed with the condition. This common problem can significantly impact daily vision and comfort.

In this article, you’ll discover how tears affect your vision, what causes dry eyes to blur your sight, and practical ways to address this common problem. We’ll explore both quick fixes and long-term solutions to help you maintain clear, comfortable vision throughout your day.

What Is Dry Eye?

Dry eye syndrome often develops in three main ways:

Your eyes might not produce enough tears, a common condition as people age or take certain medications.
Tears might evaporate too quickly, especially if the meibomian gland function is impaired.
Your tears may be missing important components, meaning they are unable to properly coat your eye surface.

When any of these problems occur, your tear film becomes unstable and breaks up too quickly between blinks, leaving dry spots that can cause both vision problems and discomfort.

Why Does Dry Eye Affect Vision?

Normal Tear Function

Tears do much more than show emotion – they’re necessary for clear vision and comfort. Every time you blink, tears spread across your cornea (the clear front surface of your eye) creating a smooth surface that allows light to focus properly.

This tear film also

Washes away dust and debris
Prevents infection
Supplies oxygen and nutrients to your cornea.

Without this constant moisturizing and protection, dry eye symptoms can cause blurry vision.

Signs that Dry Eye is Affecting Your Vision

Common Vision Symptoms

Vision Effects

Dry eye syndrome directly impacts visual clarity
Insufficient tears lead to noticeable blurry vision throughout the day
Tear film functions like a camera lens:
- Needs to be smooth and clear for sharp vision
Vision often fluctuates between clear and blurred as tear film breaks down and reforms

Associated Symptoms

Light sensitivity becomes common:
- Bright indoor lighting causes discomfort
- Sunlight may feel uncomfortable
Eye strain develops more quickly:
- Digital device use becomes more difficult
- Computer screen viewing is more challenging
- Occurs because protective tear production isn’t functioning properly

The Physical Connection

The Root Cause: Corneal Surface Changes

The cornea (clear front surface of your eye) requires constant tear production
Healthy tears keep the cornea smooth and transparent
When tears are lacking, the corneal surface becomes irregular and rough
This irregular surface scatters incoming light instead of focusing it properly

These corneal surface irregularities directly correlate with decreased visual performance in dry eye patients.

Why Vision Problems Fluctuate

Blinking temporarily spreads fresh tears across the cornea
This momentarily improves visual clarity
Vision quickly becomes distorted again when:
- Tears evaporate too quickly
- Tear composition isn’t the right consistency

This explains why dry eye-related vision problems tend to come and go throughout the day.

Warning Signs to Watch For

Pay attention if you notice:

Vision that changes between clear and blurry throughout the day
Difficulty focusing when using digital devices
Eyes that feel gritty or scratchy
Burning or stinging sensations
Watery eyes or excessive tearing
Redness in the whites of your eyes

See an eye doctor promptly if these dry eye symptoms persist for more than a few days, especially if artificial tears don’t provide relief. Early treatment can prevent corneal damage and long-term vision problems. Your eye doctor can determine the underlying cause and recommend the most effective treatment options for your specific situation.

Causes and Risk Factors

Common Causes

As we age, our eyes naturally produce fewer tears, with most people over 65 experiencing dry eye symptoms.

According to the American Academy of Ophthalmology, several health conditions can trigger dry eye syndrome, including:

Rheumatoid arthritis
Diabetes
Autoimmune disease.

The AAO also notes that taking these medications may reduce tear production:

Antihistamines
Decongestants
Blood pressure medications
Antidepressants

Hormonal changes in women, particularly during pregnancy and menopause, can also lead to chronic dry eye.

Environmental Factors

Extended computer screen time can significantly impact tear film, as people tend to blink less frequently when looking at digital devices
Dry or windy climates speed up tear evaporation
Indoor environments with air conditioning or heating can decrease air humidity
Smoke exposure and high altitudes
Poor air quality in office spaces or other workplace settings

Lifestyle Contributors

Wearing contact lenses for long periods can interfere with the natural tear film across the eye surface
Not drinking enough water throughout the day leads to dehydration, which affects tear production
Poor sleep habits can impact overall eye health and vision
Activities requiring intense focus often result in reduced blinking, which disrupts the eye’s natural moisturizing process

Making lifestyle changes to daily routines, like taking regular screen breaks and staying hydrated, can help maintain better eye moisture levels.

Conclusion and Solutions

Dry eye syndrome can definitely cause blurry vision, but there are many effective treatment options to address this common condition. Proper tear production and tear film quality are fundamental for clear, comfortable vision. When these are disrupted, both your eye health and visual clarity can suffer.

Treatment Options

Over-the-counter artificial tears provide quick relief for mild dry eye symptoms. Look for preservative-free eye drops to minimize irritation.
Lifestyle changes like using a humidifier, taking regular computer screen breaks, and staying hydrated can help maintain tear film.

3. For more significant cases, prescription medications, tear duct plugs, or specialized treatments may be needed to increase tear production and reduce inflammation.

When to Schedule an Eye Exam

Schedule an appointment with Visionary Eye Doctors if you experience:

Persistent blurry vision that doesn’t clear with blinking
Dry eye symptoms that interfere with daily life
Symptoms that don’t improve with over-the-counter drops

Our experienced eye doctors at Visionary Eye Doctors can evaluate your tear production and quality to create a personalized treatment plan. Contact us today to take the first step toward relief from chronic dry eye and blurred vision. Restore your eye comfort and clear vision!

Can Diabetic Retinopathy Be Reversed? Symptoms, Treatment & Prevention

March 28, 2025/in General Optometry /by 20North

Diabetic retinopathy cannot be fully reversed, but early-stage cases can be managed to slow or stop progression. Maintaining healthy blood sugar levels and making lifestyle changes can help preserve vision. Advanced stages often require medical intervention to prevent further damage and vision loss.

Many people with diabetes don’t experience noticeable symptoms until the condition has already caused retinal damage. That’s why regular eye exams are essential – they can detect changes in the tiny blood vessels of the retina before significant vision problems occur.

More About Diabetic Retinopathy

Diabetic retinopathy develops when high blood sugar levels damage the blood vessels in the retina, the light-sensitive tissue at the back of the eye. Over time, these blood vessels can leak fluid, become blocked, or lead to the growth of abnormal blood vessels, all of which can cause vision problems.

Stages of Diabetic Retinopathy

Nonproliferative Diabetic Retinopathy

- - Blood vessels leak fluid, leading to diabetic macular edema that causes blurry vision
  - Many people have no symptoms at this early stage

Proliferative Diabetic Retinopathy

- The retina tries to compensate by growing new blood vessels, but these are fragile and prone to bleeding and scarring
- Without treatment, this can result in severe vision loss

Managing blood sugar, blood pressure, and cholesterol levels can help slow the progression and protect your vision. Regular eye exams allow for early detection and intervention before significant damage occurs.

Signs and Symptoms

Diabetic retinopathy progresses gradually, with early symptoms including:

Blurry vision that fluctuates
Floaters (dark spots or strings in your vision)
Difficulty seeing at night or adjusting to dim light
Distorted vision, where straight lines appear wavy
Dark or empty areas in vision
Sudden vision loss (in severe cases)

Is Diabetic Retinopathy Reversible?

Once retinal blood vessels are damaged, the effects are often permanent, particularly in advanced cases where abnormal blood vessels grow or scar tissue forms. However, early intervention can significantly reduce the risk of vision loss and prevent further damage.

Early Stage vs. Advanced Stage

At the early stages of nonproliferative diabetic retinopathy, the focus is on preventing progression through controlling blood sugar, blood pressure, and cholesterol.

When caught early, diabetic retinopathy may not require immediate medical treatment but does require regular eye exams to monitor changes.

In advanced proliferative diabetic retinopathy, blood vessels are abnormal and fragile. At this stage, medical treatment is necessary to prevent permanent vision loss. Treatment methods can include laser therapy, anti-VEGF injections, and vitrectomy surgery.

The Role of Lifestyle Changes in Managing Diabetic Retinopathy

While medical treatments target existing damage, lifestyle changes help prevent worsening symptoms and protect long-term vision health.

Blood sugar control reduces the stress of retinal blood vessels
Lowering blood pressure and cholesterol prevents further harm to the tiny blood vessels in the eye
Regular exercise improves blood flow
Antioxidants and omega-3s help limit oxidative stress, which contributes to retinal damage

The Importance of Regular Eye Exams

Because diabetic retinopathy often develops without noticeable symptoms, routine eye exams are essential. Tests like optical coherence tomography (OCT) allow an eye doctor to detect subtle changes in the retina before vision problems appear.

Although this eye condition cannot be reversed, early intervention and consistent management can help preserve vision and prevent severe complications.

In-Depth Treatment Options for Diabetic Retinopathy

While diabetic retinopathy cannot be reversed, several treatments can slow its progression and prevent vision loss. The right approach depends on the severity of the condition and whether diabetic macular edema (DME) or proliferative diabetic retinopathy (PDR) is present.

Non-Surgical Treatments

For early-stage diabetic retinopathy, treatment focuses on stabilizing blood sugar levels, blood pressure, and cholesterol to reduce stress on the retinal blood vessels.

Anti-VEGF Injections are injected directly into the eye to block the growth of abnormal blood vessels and help reduce macular edema, potentially stabilizing or improving vision in some patients.
Corticosteroid Injections are anti-inflammatory agents that may be used to reduce swelling and inflammation in the retina, especially for those with persistent diabetic macular edema.

Surgical Options

When diabetic retinopathy reaches the advanced stage, surgery may be necessary.

Laser Therapy
- Focal/Grid Laser Treatment targets specific areas of the retina and seals leaking blood vessels to reduce fluid buildup and swelling.
- Panretinal Photocoagulation targets a wider area of the retina, preventing bleeding and reducing the risk of retinal detachment.

Protecting Your Vision with Expert Eye Care

Managing diabetic retinopathy requires consistent care and early intervention. While treatments can help slow progression and prevent vision loss, the best way to protect your eyesight is through proactive management and getting regular eye exams at the eye doctor.

Why Ongoing Eye Care Matters

Diabetic retinopathy often develops without noticeable symptoms, making regular eye exams essential. A comprehensive eye exam, including optical coherence tomography (OCT) and dilated retinal imaging, can detect changes in the retina before vision is affected.

Do I Really Need a Contact Eye Exam Every Year?

March 28, 2025/in General Optometry /by 20North

Yes, an annual contact lens exam is recommended for most contact lens wearers to protect eye health, maintain an accurate prescription, and detect any underlying vision problems. Even if your vision seems fine, regular exams help prevent issues like dry eye, corneal ulcers, and other eye conditions that may not have obvious symptoms.

Many people believe that once they have a contact lens prescription, they can continue using the same lenses indefinitely. However, vision changes and general wear and tear on the eyes can make old prescriptions ineffective or even unsafe.

The Importance of an Annual Contact Eye Exam

An annual eye exam isn’t just about updating your contact lens prescription – it’s an important step in protecting your eye health.

Unlike glasses, contact lenses sit directly on the eye, making wearers more susceptible to dry eye and irritation. Over time, even a well-fitted contact lens can cause subtle changes to the cornea, which may lead to discomfort if not properly monitored.

Another key reason for regular checkups is that vision changes can occur gradually. Even minor prescription shifts can lead to eye strain, headaches, or blurry vision.

What an Annual Exam Can Detect

Even if you don’t notice any changes in your vision, an annual exam can help detect:

Refractive errors that require adjustments for perfect vision
Dry eye syndrome
Early signs of macular degeneration, diabetic retinopathy, or corneal ulcers
Risk factors for vision loss, especially for those with high blood pressure or diabetes

Skipping a routine vision screening increases the risk of wearing an outdated or incorrect lens prescription, which can cause discomfort and vision problems over time. Regular exams provide an opportunity to catch issues early and adjust your vision correction as needed.

What Happens During a Contact Lens Exam?

A contact lens exam is a comprehensive evaluation that ensures your lenses fit properly, your prescription is up to date, and your eye health is protected. Unlike a regular eye exam, a contact lens exam includes additional steps to assess how your lenses interact with your eyes and whether adjustments are needed.

Step 1. Eye Health Evaluation

Before checking your prescription, your eye doctor will perform a complete eye exam to assess your overall eye health. This includes:

Checking for vision problems
Examining the optic nerve for early stages of glaucoma or macular degeneration
Looking for symptoms of dry eye, corneal ulcers, or diabetic retinopathy

Step 2. Contact Lens Fitting

Not all contact lenses are the same, and an improper fit can lead to eye irritation, blurry vision, or discomfort. During this stage, your eye doctor will:

Measure the curvature of your cornea to ensure the correct lens fit
Assess your tear film to check for dry eye issues
Update your contact lens prescription based on your latest vision examination

Even slight changes in your visual acuity can impact how well your lenses perform, which is why keeping your lens prescription current is essential.

Step 3. Trial Lenses and Final Adjustments

If you’re switching to a new type of contact lens, your eye doctor may provide trial lenses to test the fit before finalizing your prescription. They will evaluate:

How well the lenses settle on your eyes
Whether they provide clear and stable vision correction
Any signs of discomfort

Step 4. Care and Follow-Up

To help maintain eye health and prevent infections, your eye doctor will go over:

Proper contact lens care and hygiene practices
Recommended replacement schedule for your lenses
When to schedule your next annual exam or more frequent regular checkups if needed

By the end of the contact lens exam, you’ll have a personalized plan for vision correction that ensures clarity and comfort.

Who Needs More Frequent Contact Lens Exams?

While an annual eye exam is recommended, some individuals may need more frequent checkups to ensure their lenses remain safe and effective.

People at a Higher Risk for Eye Conditions

Young children: Their vision changes more rapidly, making frequent eye exams essential to ensure their contact lenses remain effective.
Individuals with health conditions: Conditions like diabetes, high blood pressure, or autoimmune diseases can increase the risk of vision problems or complications from contact lenses.
People prone to dry eye: Contact lens wearers with dry eye may need adjustments in lens material or prescription to maintain comfort and prevent irritation.

Signs You Should Schedule an Exam Sooner

Even if you don’t fall into a high-risk group, certain symptoms indicate that you should see an eye doctor sooner:

Frequent headaches or blurry vision
Redness, irritation, or discomfort while wearing contact lenses
Light sensitivity or difficulty seeing at night
A history of eye infections

Many vision insurance plans cover annual eye exams, but some policies allow for more frequent checkups for those with higher risk factors. Checking your insurance coverage can help determine whether you qualify for additional regular checkups at little or no extra cost.

Pinguecula Removal: A Cosmetic Solution for Clearer, Brighter Eyes

March 3, 2025/in General Optometry /by 20North

If you’ve noticed a yellowish patch on the white part of your eye, you may have a pinguecula. While these growths are typically harmless, they can cause eye irritation, dryness, and a foreign body sensation. For some individuals, a pinguecula’s appearance can be a cosmetic concern.

In such cases, pinguecula surgery is an option for those who want a clearer, more uniform-looking eye. While non-surgical treatments like eye drops can relieve symptoms, surgical excision may be the best choice for a more permanent solution.

What is a Pinguecula and Why Does It Develop?

A pinguecula develops due to changes in the conjunctival tissue, often as a response to long-term exposure to ultraviolet light, wind, dust, and other environmental factors. While older people are more prone to developing pinguecula, it can also appear in younger adults who spend a lot of time outdoors.

Pinguecula vs. Pterygium

While pinguecula and pterygium are often mentioned together, they aren’t the same condition.

Pinguecula is a small, raised bump that stays confined to the sclera (the white of the eye). It’s often treated with eye drops or surgical removal for cosmetic reasons.
Pterygium (surfer’s eye) is a more advanced growth that extends onto the cornea, potentially affecting vision if it grows large enough. It’s also treated with steroid eye drops or pterygium surgery if vision is affected.

Common Causes of Pinguecula and Pterygium Formation

Ultraviolet Radiation: Long-term exposure to ultraviolet rays from the sun is a primary cause of both conditions. UV light can trigger changes in the conjunctival tissue, leading to these growths over time.
Environmental Factors: Wind, dust, and dry air can irritate the eyes, increasing the risk of developing a pinguecula or pterygium.
Dry Eye and Irritation: Chronic dry eye and frequent eye irritation can contribute to these conditions, as the eye struggles to maintain proper moisture levels.
Contact Lens Wearers: Those who wear contact lenses for extended periods may experience increased irritation, which can make a pinguecula or pterygium worse.

Although a pinguecula doesn’t typically affect vision, in severe cases, it may cause discomfort or blurry vision if it becomes inflamed. This condition can lead to redness, irritation, and increased sensitivity.

For many people, a pinguecula is simply a cosmetic concern. Whether it’s due to a noticeable yellowish bump or recurring eye irritation, individuals may want pinguecula treatment to restore the natural appearance and comfort of their eyes.

Treatment Options for Pinguecula: Non-Surgical vs Surgical Removal

Most pinguecula don’t require treatment. However, depending on the severity of symptoms and personal preference, treatment can range from non-surgical approaches to surgical removal.

Non-Surgical Treatments

In mild to moderate cases, non-surgical treatments can effectively manage symptoms and improve eye comfort:

Lubricating Eye Drops: Over-the-counter artificial tears can help relieve dry eye and discomfort.
Steroid Eye Drops: If the affected area becomes inflamed or irritated, an eye doctor may prescribe steroid drops to reduce swelling.
UV Protection: Wearing UV-blocking sunglasses can help slow progression and prevent further irritation.
Avoiding Environmental Triggers: Reducing long-term exposure to wind, dust, and other irritants can help manage symptoms.

Surgical Removal: When Is It Necessary?

For those wanting a long-term solution, surgical excision may be recommended. Proper surgical removal is considered in the following cases:

The pinguecula is severely inflamed despite the use of eye drops
The pinguecula causes chronic discomfort or blurry vision
The patient wants pinguecula surgery for cosmetic reasons to restore a natural appearance to the eye

Pinguecula Surgery: What to Expect

The surgical removal of a pinguecula is a minimally invasive outpatient procedure performed by a corneal specialist or eye surgeon. It involves carefully removing the affected conjunctival tissue while preserving as much healthy tissue as possible.

To improve the cosmetic outcome and reduce the risk of recurrence, advanced techniques may be used:

Conjunctival Autograft: A small section of healthy conjunctival tissue is glued over the affected area, promoting smoother healing and improving dry eye.
Amniotic Membrane Grafting: An amniotic membrane is used to enhance healing and prevent the pinguecula from returning.
Fibrin Glue: To improve patient comfort, fibrin glue is used to secure the graft instead of traditional sutures, leading to a faster recovery time.

Most patients experience minimal downtime after pinguecula surgery. Surgical excision is generally safe, but as with any procedure, there is a small risk of recurrence, redness, or eye irritation. Following post-operative care – using steroid drops – is essential for an optimal healing process.

The Cosmetic Benefits of Pinguecula Removal

Even if a pinguecula isn’t causing significant irritation or redness, some people choose surgical removal to achieve a brighter, healthier-looking eye. Although pingueculas are harmless, they can make the eyes look discolored, red and irritated, and aged or unhealthy.

If your pinguecula is affecting your confidence or quality of life, speaking with an eye doctor can help determine if surgical removal is the best option. For many patients, the combination of advanced surgical techniques and proper aftercare leads to improved appearance with minimal downtime.

Low Vision Awareness Month: Empowering Your Vision Health

March 2, 2025/in General Optometry /by 20North

February is Low Vision Awareness Month, a time dedicated to raising awareness about low vision, its causes, and the resources available to help those affected.

Millions of people in the United States experience vision loss due to conditions like age-related macular degeneration (AMD), diabetic retinopathy, glaucoma, and retinitis pigmentosa. While these conditions can significantly impact everyday tasks, regular eye exams and vision rehabilitation can help individuals make the most of their remaining vision.

What Exactly is Low Vision?

Low vision is a permanent vision impairment that cannot be fully corrected with regular glasses or contact lenses. Unlike typical vision problems that can be managed with prescription lenses, low vision makes daily activities – such as reading, recognizing faces, and driving – more difficult, even with the best possible corrective eyewear.

Common Causes of Low Vision

Several eye conditions can lead to low vision, including:

Age-Related Macular Degeneration: A leading cause of vision loss in older adults, AMD affects central vision, making it difficult to see the fine details.
Diabetic Retinopathy: Caused by damage to the blood vessels in the retina, this condition can lead to visual impairment and blind spots.
Glaucoma: A group of diseases that damage the optic nerve, often leading to gradual vision loss that may not be noticeable at first.
Retinitis Pigmentosa: A genetic disorder that affects night vision and peripheral vision, progressing to significant impairment over time.
Cataracts: Gradually clouds the lens of the eye, leading to blurry vision and difficulty seeing at night.
Eye Injuries: Caused by a pervious trauma to the eye and retinal detachment.

While these conditions develop for different reasons, early detection through regular eye exams is crucial in slowing their progression and preserving detailed vision for as long as possible.

The Importance of Early Detection and Regular Eye Exams

Detecting vision problems early can make a significant difference in managing low vision and preserving eyesight. Many eye conditions develop gradually and may not show noticeable symptoms until vision loss has already occurred.

How Often Should You Get an Eye Exam?

The American Academy of Ophthalmology and the National Eye Institute recommend eye exams based on an individual’s age and risk factors. The following are guidelines for comprehensive eye exams:

Children (before age 18): An initial eye exam at six months, again at age three, and before starting school. After that, exams every 1-2 years help detect vision problems early.
Adults under 40: At least every 2 years, unless you have risk factors like diabetes or a family history of vision problems – in which case, annual exams are recommended.
Adults 40-60: An exam every year to check for early signs of glaucoma, diabetic retinopathy, and AMD.
Adults 60 and older: Annual exams are highly recommended as the risk of vision impairment and blind spots increases with age.

How Regular Eye Exams Can Help

Routine eye exams allow eye care professionals to:

Detect early signs of vision impairment and underlying eye conditions
Monitor risk factors like high blood pressure or diabetes, which can contribute to vision loss
Identify changes in central vision that may indicate macular degeneration
Use tools to check for blind spots or distorted straight lines

For those already experiencing low vision, regular checkups with a low vision specialist can help determine the best medical treatments and preventive measures to improve daily life.

Vision Rehabilitation and Support Resources

For those experiencing low vision, adjusting to daily tasks can be challenging, but vision rehabilitation programs provide the tools, training, and support to help individuals maximize their remaining vision.

What is Vision Rehabilitation?

Vision rehabilitation is a personalized approach involving various strategies, low vision aids, and specialized training. A low vision specialist works closely with each patient to develop a plan that meets their specific needs.

Key aspects of vision rehabilitation include:

Low Vision Aids: Devices like magnifiers, special lighting, and large-print materials designed for people with vision impairment.
Assistive Technology: Screen readers and voice-controlled devices that enhance detailed vision for tasks like reading and writing.
Occupational Therapy: Occupational therapists teach strategies like labeling household items, improving contrast in home environments, and using adaptive techniques for cooking and personal care.
Mobility Training: Mobility specialists help individuals learn how to safely navigate their surroundings at home and in public.
Emotional Support: Adjusting to vision loss can be overwhelming and lead to emotional stress. Connecting with support groups can provide encouragement and practical tips from others facing similar challenges.

Where to Find Help

There are many resources available for those living with low vision:

National Eye Institute: Offers information on vision problems, treatments, and resources for people with low vision.
Prevent Blindness: A national nonprofit dedicated to eye health education, advocacy, and patient support.
American Optometric Association: A professional organization that promotes doctrors of optometry in practice management and development.

By utilizing vision rehabilitation, individuals can maintain their independence while learning skills to make the most of their remaining vision.

What You Need to Know About Glaucoma Awareness Month

February 2, 2025/in Glaucoma /by 20North

January is National Glaucoma Awareness Month, a time dedicated to educating people about glaucoma, its risk factors, and the importance of early detection. As one of the leading causes of irreversible vision loss in the United States, glaucoma affects millions worldwide – yet many don’t realize they have it until significant damage has already occurred.

Why Awareness Matters

Glaucoma often has no noticeable symptoms in the early stages, making routine eye exams a critical part of early detection. Raising awareness for this eye condition can help people prevent themselves from permanent vision loss by promoting timely treatment and proactive eye care.

A Deep Dive into Glaucoma

Definition: Glaucoma is a group of progressive eye diseases that damage the optic nerve, leading to vision loss and, if left untreated, blindness. While most cases are associated with high intraocular pressure (IOP), some types can develop even when eye pressure is within a normal range.

How Glaucoma Affects Vision

The optic nerve is responsible for transmitting visual information from the eye to the brain. When glaucoma damages this nerve, it disrupts vision – typically starting with small blind spots in peripheral vision. Over time, optic nerve damage can progress, leading to significant vision impairment or complete blindness.

Types of Glaucoma

Open-Angle Glaucoma

The most common type – develops when the eye’s drainage system becomes blocked.
Progresses slowly and often goes unnoticed until vision loss occurs.

Angle-Closure Glaucoma

A sudden and severe blockage in the eye’s drainage canals causes a rapid rise in eye pressure.
Symptoms are severe eye pain, blurred vision, nausea, and headaches.

Secondary Glaucoma

Caused by underlying conditions like diabetic retinopathy, cataracts, or eye trauma.
Treating the underlying cause can help manage this type of glaucoma.

Congenital Glaucoma

Rare and present at birth – occurs due to abnormal eye development in newborns.
Early signs include excessive tearing, light sensitivity, and an enlarged eye.

Who is Most at Risk for Glaucoma?

Certain people have a higher likelihood of developing glaucoma due to genetic, medical, and lifestyle factors. Those at greater risk include:

African Americans and Hispanics, especially at a younger age
Individuals over 40 years old
People with long-term steroid use
People with a family history of glaucoma
Individuals with high intraocular pressure (IOP)
Those with chronic conditions – diabetes, heart disease, or extreme nearsightedness
People with past eye injuries, thin corneas, or drainage problems

Early Symptoms and Warning Signs

Many people are unaware of glaucoma until significant vision loss has occurred. Some warning signs that may indicate glaucoma include:

Blurred vision
Frequent headaches
Eye strain
Halos around lights
Difficulty adjusting to low light
Patchy blind spots in side vision

Importance of Regular Eye Exams

A comprehensive eye exam is the most reliable way to detect glaucoma early. Since these symptoms often go unnoticed until irreversible damage has occurred, routine screenings are crucial – especially for those at higher risk.

The National Eye Institute recommends annual glaucoma screenings for individuals with risk factors to ensure early diagnosis and treatment.

Glaucoma Prevention and Treatment Options

While glaucoma cannot be cured, early diagnosis and proactive care can help prevent significant vision loss. Steps to reduce risk and slow progression include:

Regular comprehensive eye exams – the best way to catch glaucoma early and prevent permanent damage. Get regular eye exams:
- Before age 40 – every 2 or 3 years
- From age 40 to 54 – every 1 to 3 years
- From age 55 to 64 – every 1 to 2 years
- After age 65 – every 6 to 12 months
Maintaining a healthy lifestyle – regular exercise, a balanced diet, and hydration can help lower intraocular pressure.
Managing underlying health conditions – controlling blood pressure and diabetes supports overall eye health.

Glaucoma Treatment Options

Although glaucoma damage is irreversible, appropriate treatment can slow or prevent further vision loss. Treatment plans are tailored to each patient’s needs and may include:

Prescription Medications

Prescription eye drops that help maintain eye pressure at a healthy level. They measure changes in the peripheral visual field, helping to improve fluid drainage or decrease fluid production.

Laser Treatments for Glaucoma

Selective Laser Trabeculoplasty uses short pulses to target specific cells in the eye’s drainage system and stimulate improved function. This procedure can slow or stop the risk of disease progression.

Surgical Procedures

Minimally Invasive Glaucoma Surgery (MIGS) – A less invasive option that improves drainage. Widely accepted as one of the most successful techniques for mild-to-moderate glaucoma.
Trabeculectomy – A traditional surgery that creates a new drainage pathway to reduce pressure. It’s performed when eye drops or laser surgery aren’t effective.

Lifestyle Adjustments

Managing blood pressure and diabetes, maintaining a nutrient-rich diet, and avoiding habits that increase eye pressure (such as smoking) can support long-term eye health.

Can LASIK Fix Astigmatism? Everything You Need to Know

February 2, 2025/in General Optometry /by 20North

Can LASIK fix astigmatism? The answer is yes. LASIK is a popular and effective refractive surgery that corrects common vision problems like nearsightedness, farsightedness, and astigmatism.

Understanding the Basics of LASIK

LASIK (Laser-Assisted in Situ Keratomileusis) is a widely performed refractive surgery that improves vision and eye health. Developed in the 1990s, LASIK has advanced significantly, offering patients a safe and effective way to reduce or eliminate their dependence on corrective lenses like glasses and contacts.

How Does LASIK Work?

The LASIK surgical procedure is quick and minimally invasive, typically taking less than 15 minutes for each eye:

Creating the Corneal Flap: Anesthetic eye drops are applied to numb the eye. A femtosecond laser is then used to create a thin flap with precise dimensions.
Reshaping the Cornea: The surgeon lifts the flap to access the underlying corneal tissue and uses an excimer laser to reshape it – correcting refractive errors.
Repositioning the Flap: After reshaping, the flap is carefully repositioned, adhering naturally without the need for stitches.

Vision Problems Addressed by LASIK

LASIK is designed to treat the following eye conditions:

Nearsightedness (Myopia): Improves distance vision by flattening the cornea.
Farsightedness (Hyperopia): Enhances near and intermediate vision by steepening the cornea.
Astigmatism: Corrects an irregularly shaped cornea by improving overall visual acuity.

By addressing these refractive errors, LASIK provides long-term vision correction, helping patients achieve clearer sight with minimal downtime.

Astigmatism Explained

Astigmatism is a common refractive error caused by an irregular shape of the cornea or lens. Instead of being perfectly round like a basketball, an eye with astigmatism has an uneven shape, more like a football, that causes blurred vision and distortion.

Types of Astigmatism

There are two main types of astigmatism, each affecting vision differently:

Regular Astigmatism: The cornea curves more in one direction than the other, creating a consistent distortion that can typically be corrected with glasses, contact lenses, or LASIK surgery.
Irregular Astigmatism: The corneal curvature is uneven or asymmetrical, often caused by injury, scarring, or conditions like keratoconus. This type may require specialized contact lenses or alternative treatments.

Ranging from mild to severe, astigmatism is measured in diopters:

Slight: up to .75 diopters
Mild: .75-2 diopters
Moderate: 2-4 diopters
Severe: 4 more or diopters

Traditional Vision Correction Procedures

Astigmatism is commonly corrected through:

Eyeglasses: A simple and effective solution that compensates for corneal irregularities.
Contact Lenses: Toric lenses are specially designed to correct astigmatism by aligning with the cornea’s unique shape.
Refractive Surgery: A LASIK procedure reshapes the cornea to create a more uniform curve, improving light focus and reducing or eliminating the astigmatism.

By understanding astigmatism and its correction options, patients can make informed decisions about the best treatment to achieve clearer, sharper vision.

LASIK’s Role in Correcting Astigmatism

During LASIK laser eye surgery, a highly precise laser removes microscopic amounts of corneal tissue. This process enhances the way light is refracted onto the retina, reducing blurry vision. LASIK has proven to be an effective, long-term solution for astigmatism, providing many patients with sharper sight without the need for glasses or contacts.

The Technology Behind LASIK for Astigmatism Correction

LASIK relies on advanced technology to ensure precision and safety when treating astigmatism.

Femtosecond Laser: This ultra-fast laser creates a thin, customized corneal flap with extreme accuracy. The flap gives the eye surgeon access to the underlying corneal tissue while maintaining the integrity of the eye’s surface – which helps to minimize post-surgical complications and ensure a smooth recovery.
Excimer Laser: This specialized laser reshapes the cornea by removing microscopic layers of tissue. These lasers are computer-controlled and use a light beam to minimize risks of thermal damage to the tissue.
Corneal Topography Mapping: Before LASIK, a detailed 3D image of the cornea is generated using corneal topography. These tools measure even the smallest imperfections in the cornea so the surgeon can precisely correct the astigmatism.

These technological advancements allow for highly individualized treatment, ensuring that each patient receives optimal results tailored to their unique corneal structure.

Comparing LASIK to Other Refractive Surgeries

For patients with astigmatism, LASIK is often the preferred choice, but other procedures may be considered based on individual eye health:

PRK (Photorefractive Keratectomy): Similar to LASIK but without a corneal flap; best for those with thinner corneas because it preserves more corneal tissue. However, PRK has a longer recovery period and can cause temporary discomfort.
ICL (Implantable Contact Lens): An alternative for patients who are not LASIK candidates and don’t want to permanently alter their cornea. Involves the insertion of an implantable lens inside the eye to correct vision.

Who is a Good Candidate for LASIK?

For patients with astigmatism, eligibility for LASIK depends on several factors, including:

1. Stable vision prescription for at least a year

At least 21 years old

Sufficient corneal thickness to allow for safe reshaping
Overall eye health, free from conditions like keratoconus or severe dry eye

With its precision and long-lasting results, LASIK remains one of the most effective options for astigmatism correction.

Why Trust Visionary Eye Doctors for LASIK Eye Surgery

Choosing where to have LASIK is just as important as deciding to have the procedure itself. At Visionary Eye Doctors, we combine advanced technology with expert surgical care to provide a seamless, patient-focused experience.
