A cornea transplant is an operation used to remove all or part of a damaged cornea and replace it with healthy cornea tissue from the eye of a suitable donor.
Most patients who have corneal transplants donât have severe complications, but they can occur. Rejection of the cornea is a possibility, along with infection. Medication may be given to treat rejection if it occurs. Occasionally increased pressure in the eye can also occur after surgery. Additional procedures to adjust the cornea may be needed as the eye heals. The amount of vision which is restored through a transplant varies, and partially depends on the condition which lead to the cornea transplant.
