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 a skilled surgeon like Dr. McMann.
Note: 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 - Everyone's cornea
is a different size. 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. |
