The cornea is the transparent part that covers the eye from the outside, protecting it from getting in the eye, dirt, etc. The function of the cornea is to refract light rays as they enter the eye, so it plays an important role in the retina’s ability to focus on an image.
A corneal transplant (keratoplasty) is a surgical procedure to replace a portion of the cornea with corneal tissue from a donor. The cornea is the transparent dome-shaped surface of the eye that accounts for a large portion of the eye’s ability to focus
A corneal transplant can restore vision, reduce pain, and improve the shape of a damaged or diseased cornea.
Most corneal transplants are successful. But a corneal transplant carries a small risk of complications, such as rejection of a donor cornea.
