Advanced Sutureless Amniotic Membrane Pterygiectomy (ASAP)
ASAP is an incredibly successful, advanced autograft technique using tissue “glue” for no-stich pterygium removal surgery. The ASAP procedure has endlessly evolved over the years with one of the lowest recurrence rates in the world – 0.06% in 2016 – and with excellent cosmetic results.
What Happens During ASAP?
During the ASAP procedure:
- The abnormal corneal tissue is removed and replaced with a thin graft of normal tissue.
- No-stitch pterygium surgery is made possible by the use of modern tissue adhesive composed of clotting proteins normally found in human blood. Tissue adhesive allows the surgeon to secure a conjunctival autograft in seconds rather than minutes. After about one week the tissue adhesive dissolves, leaving no residue, and the eye heals comfortably.
- An amniotic membrane will be placed in the eye to aid the healing process and decrease inflammation.
The ASAP procedure shows a proven ability to prevent scar tissue and is used to reduce the chance of regrowth after pterygium removal to less than 1%.
Recovery After Pterygium Removal
After the ASAP surgery, there may be a small amount of pain for a day or so. Your eye initially might feel itchy, gritty, or a bit dry. Sensitivity to light is also possible.
These side effects should subside after a few days. Next-day and two-week follow-up appointments will be scheduled to ensure your eye is healing properly.
You will need to keep your eye covered for the first day, and at night or in dirty environments for one month after surgery.
