Corneal Transplants - Keratoplasty

Keratoplasty is the transplant of a donor cornea to replace part of or your entire cornea. Keratoplasty is performed to treat a variety of conditions including:

Keratoconus - where your cornea bulges outward
Swelling or scarring of the cornea - can happen by injury to the eye or infection
Thinning of the cornea
Corneal ulcers
Complications caused by previous eye surgery

After the procedure, you should experience relief from pain or discomfort that is associated with these conditions. As with any transplant, there are risks, such as a rejection of the donor cornea. However, most Keratoplasty procedures are successful, particularly in the hands of an experienced skilled surgeon like Dr. McMann.
Cornea Surgery
 
If you think you are experiencing symptoms of donor rejection
(sensitivity to light, loss of vision, pain, or redness in the eyes), make an appointment with us right away.
 
The following steps must be taken prior to the procedure:

1. Eye Exam

Dr. McMann will perform a thorough eye examination to look for any existing conditions that might cause complications after the procedure. If you have any other unrelated eye problems, these will be treated prior to surgery.


2. Eye Measurements

We will need a proper measurement of your eye so Dr. McMann can determine what size cornea will be needed for the replacement.


During the Procedure

Keratoplasty is virtually painless and your eye will be numbed during the procedure. Dr. McMann will cut through the cornea and remove the tissue (about the size of a button). Then the donor cornea (already sized to fit) is stitched into place. In a partial cornea replacement, Dr. McMann will remove only those layers that need removing. For the inside layers, a very small incision will be made to allow for the removal and replacement without disturbing the outside of your eye. For the outside layers, they will simply be removed and replaced.


After the Procedure

You will receive eye drops and an oral medication to prevent infection. You will be required to wear a protective eye covering consisting of gauze to reduce swelling and metal to prevent injury or trauma to the eye. Follow-up exams are necessary after Keratoplasty and the frequency of these exams will depend upon your specific procedure and healing process.


Descemet's Stripping Endothelial Keratoplasty (DSEK)

Dr. McMann is a member of a very small group of surgeons worldwide performing a new form of a corneal transplant procedure called "DSEK" which stands for Descemet's Stripping Endothelial Keratoplasty. Dr. McMann was the first surgeon to ever perform a DSEK at Tripler Army Medical Center.

About 50,000 corneal transplants are performed each year in the United States, often for patients with corneal swelling or edema. In DSEK, only the thin damaged back layer or endothelium is replaced, leaving most of the patient's cornea in place. The expected results include faster return of vision, reduced risks of some complications, and a faster return to daily activities.

Not all patients who require corneal transplants are candidates for DSEK. This procedure is best suited for those who have corneal edema or swelling. Please call us to schedule an appointment to determine if DSEK is for you.


Corneal Dystrophies

The cornea is the outer layer of your eye and it should be transparent to allow the focus of incoming light. Corneal dystrophy is traditionally a hereditary disease that happens when abnormal material grows or accumulates within one or more layers of the cornea of both eyes. There are multiple types of corneal dystrophy, classified by which layer of the cornea the disease affects and the specific infection or growth.

Some corneal dystrophies can create vision impairment while others may have no symptoms at all. Corneal erosion is a common symptom found with multiple forms of corneal dystrophy. This symptom causes discomfort or even extreme pain as the epithelium layer of the cornea separates from the eye.

Corneal dystrophies can be found during routine eye exams and some can be diagnosed with molecular genetic tests, often before symptoms begin to surface. Treatments will vary depending on the specific type of corneal dystrophy, ranging from observation to eye drops, ointments, antibiotics, special contact lenses, or even excimer laser treatment.

Genetic counseling may be of benefit for affected individuals and their families. Other treatment is symptomatic and supportive. If you have corneal dystrophy in your genetics, regular exams are the best preventative treatment. If you think you might be experiencing corneal dystrophy, please call us to make an appointment.
