Pterygium Surgery

It is sometimes called “surfer’s eye” because it is more common in people who spend a lot of time outdoors in the sun and wind.

Pterygium can cause redness and eye irritation. It can affect vision if it grows across the cornea or distorts its shape. It can also cause cosmetic concerns due its appearance. Very occasionally it contains early cancer cells which if left unchecked, can result in a squamous cancer of the conjunctiva.

Surgery is recommended when a pterygium causes persistent discomfort not relieved by drops, or if it grows toward the centre of the cornea and threatens vision. A common reason for removal of pterygium is its cosmetic appearance.

The operation which takes less than 30 minutes, involves careful removal of the pterygium and coverage of the area with a thin graft of conjunctiva (a conjunctival autograft), secured in place with tissue glue rather than sutures. This technique is the gold standard, and it significantly reduces the risk of recurrence. It also allows rapid healing and minimal discomfort in the post-operative period.
