If the pterygium is growing towards your visual axis or has the potential to cause vision disturbance, surgical intervention is usually recommended. The surgery is a quick procedure that only last for half an hour. Patients will be light sedated and their eyes will be completely numb. The surgery consists of removing the Pterygium and replacing it with graft or tissue which is glued into place. After the surgery, you won’t be able to drive yourself home due to the sedation. You’ll be able to return to work in about 2 days.
