Pterygium is a fibrovascular fleshy growth that grows progressively over the cornea. It is relatively common in countries in around the equatorial belt, which includes Singapore. It is a benign condition but it may cause deterioration of vision due to astigmatism or progressive encroachment over the visual axis. It may also cause recurrent redness and irritation of the eye.
Pterygium surgery aims to remove the pterygium and helps to prevent visual deterioration from progressive growth of the pterygium. The surgery also helps to reduce the redness and improves the cosmetic appearance of the eye.
Pterygium surgery is a procedure in which the pterygium is surgically removed and a conjunctival graft is placed over the site of excision to prevent recurrence after surgery. The conjunctival graft is harvested from the area underneath the upper lid of the eye (bulbar conjunctiva), and is either stitched or glued in place over the previous site of the pterygium. This is performed as a day surgery procedure and the patient can return home after the surgery.
