Pterygia are triangular folds of fibrovascular tissue on the front of the eye that runs from the conjunctiva over the cornea. 


Pterygia occur due to chronic irritation of the conjunctiva from sun exposure, wind, dust and dryness.

How does pterygium surgery work?

Pterygium surgery aims to remove the entire pterygium membrane with as little inflammation and scarring as possible.

How do you remove the pterygium membrane?

Dr McClunan removes the pterygium together with the damaged conjunctiva tissue and replaces it with a graft of healthy tissue to stop the recurrence of pterygium growths. He uses fibrin glue which is a type of tissue adhesive to secure the graft in place without needing any stitches. Within a week, the fibrin glue dissolves completely without a trace of residue and minimises the risk of pterygium recurrence. Dr McClunan fits a bandage lens over the eye for a few days to prevent any interference and protect it against irritants.

Can pterygium return?

Previously, surgeons removed the pterygium from the conjunctiva and sewed the gap closed. The result? In about a year, the pterygium usually grew back. By Dr McClunan using the most modern techniques as described above, the recurrence of pterygia can be reduced to between 2% and 5%.
