Corneal transplantation, also known as corneal grafting or penetrating
keratoplasty, is a surgical procedure where a damaged or diseased cornea is
replaced by donated corneal tissue. The cornea is the clear part of eye in
front of the iris and pupil. An unhealthy cornea affects your vision by
scattering or distorting light and causing blurry or glary vision. A cornea
transplant may be necessary to restore your functional vision. The surgical procedure
is performed by ophthalmologists, medical doctors who specialize in eyes and
are often done on an outpatient basis.
A cornea transplant may be
suggested due to any of the following reasons:

PROCEDURE:
|
On the day of the surgery, the
patient is given a brief physical examination by the surgical team and is
taken to the operating room in the hospital or an outpatient surgery center.
A local or general anesthesia may be used, depending on the health, age of
the patient and whether or not you prefer to be asleep during the procedure.
With local anesthesia, an injection into the skin around your eye is used to
relax muscles that control blinking and movement and eye drops are used to
numb the eye itself.
An eyelid speculum is used to keep
the lids open, along with suitable lubrication to prevent the eye from
drying. A metal ring is then stitched to the sclera, which will provide a
base for a trephine. The surgeon inspects and measures the affected corneal
area in order to determine the size of the transplantation. A trephine
is then placed over the cornea and is used by the surgeon to cut the host
cornea. The trephine is then removed and the surgeon cuts a circular graft
from the donor cornea. A tissue nearly identical in shape is then sutured
into place. Once this is done, the surgeon returns to the patient's eye and
removes the host cornea.
The donor cornea is then
brought into the surgical field and maneuvered into place with forceps. Once
in place, the surgeon will fasten the cornea to the eye with a running stitch
(as used in the upper image above) or a multiple interrupted stiches (as in
the lower image). The surgeon finishes up by reforming the anterior chamber
with a sterile solution injected by a cannula, then testing that it's
watertight by placing a dye on the wound exterior.
With the metal ring removed and
antibiotic eye drops placed, the eye is patched and the patient is taken to a
recovery area while the effects of the anesthesia wear off. The patient
typically goes home following this and sees the doctor the following day for
the first post operative appointment.
A plastic shield will be put over your
eye to protect it from being inadvertently rubbed or bumped. The procedure
takes approximately two hours.
