Dear curlyq33,
I would recommend you discuss with your doctor as intervention is dependent upon how much the pterygium is encroaching on the cornea, your symptoms and likelihood to affect vision. Surgical removal with newer techniques has dramatically reduced the recurrence rate. It might be possible to use a nonsteroidal anti-inflammatory if there is inflammation. These are questions that you should discuss with your eyeMD.
