If the eye disease affecting the cornea (the clear front surface of your eye) is too severe, we may need to replace the cornea with a donor cornea.
We call this a corneal transplant procedure (also called cornea grafting or keratoplasty).
Severe keratoconus is one possible reason for corneal transplant surgery. But we also use this procedure to treat corneal dystrophies and corneal scarring (possibly as a result of injury, swelling or infection of the cornea).
We typically perform corneal transplants to help restore the vision. But we can also use it to improve comfort and appearance.
