Corneal Transplantation: An Introduction, By Mark Hornfeld, DO
Corneal transplantation, or keratoplasty, involves the thin, transparent covering that shields the eye from the outside world. This structure, the cornea, helps the eye focus light in the same way a camera’s lens does. Vision problems are often caused by misshapen corneas, and can be corrected with contact lenses, glasses, or laser eye surgery.
Corneal transplantation becomes necessary when problems with the cornea go beyond its shape. In cases of scarring, swelling, or infection of the cornea, a transplant may be the only option. Today, thanks to improvements in laser technology, surgeons performing corneal transplants can achieve a much greater level of precision than was possible when transplants were completed by hand.
In a corneal transplant, the surgeon removes the cornea from a donor and from the patient. With lasers, the surgeon cuts the edges of the corneas so that they can fit together precisely, as a lock fits into a key, and puts the donor cornea in the patient’s eye.
