I agree with Dr. Rubinfeld, and, also, know that the procedure is not painful, but the healing is.
This sounds completely consistent. Salzmannn's degeneration is accumulation of scar tissue (often elevated and "bumpy") on the clear window of the front of the eye called the cornea. Surgery is often successful and it's best to do it before it gets very advanced. The cause it not totally understood but usually involves chronic trauma or irritation. It might be best if the surgery is performed by a cornea specialist. -RSR
