Pterygium: Can it come back once it's treated?
Doctor Answers 3
Yes, it can come back
Absolutely, regrowth is a risk in pterygium surgery. There are certain techniques that can be used in order to minimize the risk of recurrence, especially in cases of re-operations. For example intraoperatively using an conjunctival autograph and/or a medication called Mitomycin C can help. Also your post surgical medical eyedrop regimen can be an important factor as well.
Also sunglasses and UV protection are important for lowering your changes of recurrence.

Can the pterygium return after surgery?
The usual recurrence rate for a first time removal using the Gold Standard of conjunctival autograft is between 5 and 15%. However, simply scraping the pterygium off with no other agents used, such as mitomycin or radiotherapy, may result in recurrence rates of up to 80%.
P.E.R.F.E.C.T for PTERYGIUM® has the lowest reported rate of recurrence of 1 in 1000 patients. As well the cosmetic result has not been equalled.
Recurrence rates for a pterygium removal after previous removals is considerably worse. With many methods this may be as high as 20-30%.
With P.E.R.F.E.C.T for PTERYGIUM® the recurrence rate is higher than after a first time removal but still much better than other methods, at about 1 in 100.
