Corneal Transplant

Corneal Transplants (Penetrating Keratoplasty, Corneal Graft Surgery and DSAEK)

The cornea is the clear membrane on the outside of the eye that covers the iris and pupil. If it becomes injured or diseased, a cornea from a donor eye bank may be necessary. Conditions requiring corneal transplant include: scarring after infection, especially herpes; corneal failure following eye surgery; steep curving of the cornea; hereditary corneal failure; rejection after first corneal transplant; and injury.

The DSAEK technique (Decemet’s Stripping Automated Endothelial Keratoplasty) is a more recent form of corneal transplantation that uses only the inner portion of the cornea. Using this technique in selected corneal diseases few or no sutures are required and the recovery of vision can be quicker than conventional corneal transplants because of quicker healing and less astigmatism.
