Your cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye's focusing power. A cornea transplant (keratoplasty) is a surgical procedure to replace part of your cornea with corneal tissue from a donor.
A cornea transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea.
Blindness is a major health problem in developing countries like India. The major causes of blindness in India are cataract and glaucoma, followed by corneal blindness.
