Overview

A cornea transplant (keratoplasty) is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye. It's where light enters your eye and is a large part of your eye's ability to see clearly.

A cornea transplant can restore vision, reduce pain, and improve the appearance of a damaged or diseased cornea.

Most cornea transplant procedures are successful. But cornea transplant carries a small risk of complications, such as rejection of the donor cornea.
