Corneal Transplants

Ophthalmologists (Eye MDs) perform more than 40,000 corneal transplants each year in the United States. Of all transplant surgery done today including heart, lung and kidney, corneal transplants are the most common and successful.

What Is The Cornea?

The cornea is the clear front window of the eye that covers the colored iris and the round pupil. Light is focused while passing through the cornea so we can see.

How Can An Unhealthy Cornea Affect Vision?

If the cornea is injured, it may become swollen or scarred, and its smoothness and clarity may be lost. Scars, swelling or an irregular shape can cause the cornea to scatter or distort light, resulting in glare or blurred vision.

A corneal transplant may be needed if:

  • Vision cannot be corrected satisfactorily with eyeglasses or contact lenses.
  • Painful swelling cannot be relieved by medications or special contact lenses.

What Conditions May Cause The Need For A Corneal Transplant?

  • Corneal failure after other eye surgery, such as cataract surgery.
  • Keratoconus, a steep curving of the cornea.
  • Hereditary corneal disease, such as Fuch's dystrophy.
  • Scarring after infections, including after herpes keratitis.
  • Rejection following a prior corneal transplant.
  • Scarring after injury.

What Happens If You Decide To Have A Corneal Transplant?

Before Surgery

Once you and your ophthalmologist decide you need a corneal transplant, your name is put on the list at the local eye bank. Usually the wait for a donor cornea is not very long. Before a cornea is released for transplant, the eye bank tests the human donor for various viruses, including those that cause hepatitis and AIDS. The cornea is carefully checked for clarity. Your ophthalmologist may request that you have a physical examination and other special tests. If you usually take medications, ask your doctor if you should continue using them.

The Day of Surgery

Surgery is often done on an outpatient basis. You may be asked to skip breakfast, depending on the time of your surgery. Once you arrive for surgery, you will be given eye drops and perhaps a sedative to help you relax. Either local or general anesthesia is used, depending on your age, medical condition, and eye disease. You will not see the surgery while it is happening. Your eye will be held open with a lid speculum.

The Operation

The eyelids are gently opened. Your ophthalmologist will view your eye through a microscope and measure your eye for the corneal transplant. The diseased or injured cornea is carefully removed from the eye.

Any necessary additional work within the eye, such as removal of a cataract, is completed. In a full thickness corneal transplant, also known as a penetrating keratoplasty (PK), the clear donor cornea is then sewn into place. In a partial thickness corneal transplant, also known as an endothelial keratoplasty (DSEK), only the diseased endothelial cells are carefully removed from the eye. A partial thickness corneal graft including a layer of healthy endothelial cells is then isolated from the donor tissue and inserted into the surgical eye through a small incision. When the operation is over, your doctor will usually place a patch or shield over your eye.

After Surgery

If you are an outpatient, you may go home after a short stay in the recovery area. You should plan to have someone drive you home. An examination at the doctor's office will be scheduled for the following day.

You will need to:

  • Use the eye drops as prescribed.
  • Be careful not to rub or press on your eye.
  • Use over-the-counter pain medicine, if necessary.
  • Continue normal daily activities but avoid strenuous exercise or activities.
  • Wear eyeglasses or an eye shield for protection, as advised by your doctor.
  • Ask your doctor when you can start driving again.
  • Call your doctor if you have any questions about your home-care instructions.

Your ophthalmologist will decide when to remove the stitches, depending upon the health of your eye and rate of healing. In full thickness corneal transplant cases, it may be one year before stitches are fully removed.

A successful corneal transplant requires care and attention on the part of both patient and physician. However, no other surgery has so much to offer when the unhealthy cornea is deeply scarred or swollen.

Corneal transplant surgery would not be possible without the thousands of generous donors and their families who have donated corneal tissue so that others may see.
