If you need a cornea transplant, you will receive healthy cornea tissue from a deceased donor. In these situations, you, the patient, are also called a recipient since you are receiving eye tissue from a donor.
Two Types of Corneal Transplant Surgery
There are two main types of corneal transplant procedures:
- Full thickness corneal transplant (also known as penetrating keratoplasty)
- Partial thickness corneal transplant (also known as lamellar keratoplasty, which includes endothelial keratoplasty)
Your eye surgeon will determine which procedure is best for you based on your condition.
Both procedures have a high success rate of 95-99 percent.
During a penetrating keratoplasty, surgeons remove a circular, button-shaped, full thickness section of tissue from your cornea, usually when your cornea is injured or diseased. Then, surgeons position and suture into place a matching “button” of healthy corneal tissue from a donor. Utah Lions Eye Bank provides this healthy tissue for your transplant surgery.
A penetrating keratoplasty generally takes one to two hours. In most cases, you can go home soon after surgery.
During an endothelial keratoplasty, your ophthalmologist makes a tiny incision and places a thin disc of donor tissue on the back surface of your cornea. The Utah Lions Eye Bank provides this healthy tissue for your transplant surgery.
Your ophthalmologist then uses an air bubble to move the new endothelial layer into place.
This small incision will heal on its own. You may need one to two sutures (stitches) to close the incision.
Length of Surgery & Recovery
An endothelial keratoplasty generally takes sixty to ninety minutes. In most cases, you can go home soon after surgery, and the healing time is generally faster than with a penetrating keratoplasty. A penetrating keratoplasty generally takes one to two hours. Similar to an endothelial keratoplasty, you can usually go home soon after surgery, but healing time can take longer.
