I had a pterygium excision and graft in one eye a few months ago, and finally got my "all done" release just a few weeks ago. There's a risk of it coming back, so important that we keep an eye on that eye,
It was uncomfortable and itchy for a few weeks, lots of aftercare with antibiotic drops and eye guards. But the surgery restored the vision in that eye to near 20-20, so a very happy ending to the ordeal.
