Pterygium surgery is an outpatient procedure that is performed under local anesthesia to remove pterygia from the eye. In advance cases where the benign growths affect your vision or quality of life, surgery would most likely be the only effective treatment.
During the surgery, the pterygium along with some associated conjunctiva tissue will be removed and replaced with a graft of associated membrane tissue in order to prevent pterygium regrowth. The surgeon may use sutures or fibrin glue in order to fix the conjunctive tissue graft.
Following the surgery, feeling discomfort or redness, or even blurriness in your eye is quite normal. One of the most common complications of this surgery is recurring pterygia.
