transplant surgery involves the removal of a patient’s diseased or
damaged cornea and replacing it with a healthy donor cornea.
The cornea is the clear element at the front of the human eye, which
begins to refract (focus) incoming light and pass it through to the
inner eye. When the cornea becomes misshapen, cloudy, scarred
or otherwise damaged, there are a variety of treatments
available. An ophthalmologist resorts to a corneal
transplant when other methods of treatment have been exhausted.
The corneal transplant is the most commonly performed, and most
successful, of all transplant surgeries.

specialized treatments, corneal transplant surgery is a viable
the decision is made to undergo corneal transplant surgery, a
suitable donor cornea must be obtained. This is done through an
eye bank. Each potential donor is carefully screened, both for
diseases that could be transmitted and for clarity. The surgery
is usually an outpatient procedure. In preparation the doctor
may choose either a local or general anesthetic, whichever is most
appropriate for the patient. A speculum is used to hold the eye
surgeon uses a trephine (circular) blade to extract the host cornea.
A similar portion of tissue is cut from the donor cornea, and placed
in the host eye. This is then sutured with extremely thin
stitching. The doctor administers antibiotic eye drops, then a
patch over the eye.
patient is advised to rest the day of the surgery. There will
be a post-operative appointment with the doctor the next day.
After this, the patient may resume gentle tasks and activities, but
must wear glasses or a shield to protect the eye, and administer eye
drops as instructed by the physician. After several weeks, more
strenuous activities (like exercise) may be carefully resumed.
The stitches may be left in the eye anywhere from a few months to a
year or longer. The patient must continue to remain vigilant
for signs of complication, and contact the eye doctor immediately
upon any abnormal occurrence.
