In a corneal transplant, the central part of a cloudy or diseased cornea is removed
and replaced with healthy corneal tissue from a donor. “Graft” is another word that
is frequently used for “transplant”.

Ophthalmologists perform over 50,000 corneal transplants each year in the United States. Of all transplant surgery done today, including hearts, lungs and kidneys, corneal transplants are by far the most common and successful.
