What are corneal transplants used for?

Corneal transplants are used to restore sight to people who are partially or completely blind because of a problem with their own cornea – the clear pillow at the front of the eye.

Both the cornea and the sclera (the white of the eye) can also be used in tissue transplants. A single eye tissue donor can help between two to four people.
