The usual reason for performing a transplant is to help you to see better. For some people, however, the operation may be advised to help in the treatment of chronic pain and irritation in the eye. In these cases, the operation may be worthwhile even if it does not greatly improve your vision.

What can I expect after the procedure?
You will need someone to drive you home. If the procedure is performed under local anesthesia, you can go home after a short stay at the center. The use of general anesthesia will delay your leaving by about two additional hours; to be sure the effects are wearing off.
What can I expect after transplant surgery?
At 3 months you will start having your sutures removed and they should all be removed by the end of 6 months a little longer if you are older. At the end of 6 months you will be fitted with glasses or contact lenses. During the whole 6-month period you will take anti -rejection drops and antibiotic drops approximately 4 times a day.
For the first 6 weeks heavy exercise and lifting of heavy objects will be prohibited but otherwise you can live a normal life. Most people return to work 3-7 days after their surgery depending on the type of work they do.
An extremely important part of the recovery period is constant vigilance as to signs of rejection. Rejection occurs in 5-30% of all transplants and there is an increased risk if this operation is a second transplant after rejection of an initial one. If the rejection is noticed early, medication can be administered that will halt the reaction and save the transplant.
Rejection occurs because the body’s immune system recognizes the donor tissue as foreign and mounts a response against it. This damages the tissue such that it can no longer maintain the fluid balance, causing it to swell and lose clarity. Although the tissue will not fall out of the eye upon rejection, another transplant may be necessary to replace the tissue if too much damage occurs.
There are four signs of rejection that can be remembered by the mnemonic RSVP: redness, sensitivity to light, decreased vision, or pain. Any of these four symptoms, experienced after the initial healing period, should be reported to your ophthalmologist immediately.
