The cornea is the clear dome shaped lens on the front surface of the eye. The cornea, along with the lens within your eye is responsible for clearly focusing light on the retina. For patients that have advanced corneal diseases such as keratoconus, or may have severe scarring, a corneal transplant may be required in order to see clearly. Corneal transplants, often referred to as keratoplasty or penetrating keratoplasty, are a surgical procedure that removes the damage corneal tissue and replaces it with a donor cornea.
Corneal transplants can help patients regain clear vision and improve the appearance of diseased cornea. Corneal transplants are extremely successful, however a small percentage of patients may have complications, such as rejection of donor tissue or infection.
