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:
Excessive
swelling (edema) on the cornea
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.
