If the cornea becomes damaged, light entering the eye is distorted and causes our vision to appear blurry. There are several ways that the cornea can become damaged; these may include injury, disease, infection, or a previous eye surgery. Sometimes damage to the cornea is mild enough that it may be repaired to restore vision; however, if damage is more severe a corneal transplant may be necessary.

A corneal transplant involves the removal of the central portion of the diseased cornea, which is replaced with a healthy donor cornea. First, you are given eye drops and medication to help you relax. Next, the central, damaged part of the cornea is carefully removed from the eye. Finally, the healthy donor cornea is securely sewn into place.

Once your cornea transplant is completed, medications are prescribed to help control infection, swelling and pain as well as prevent corneal graft rejection. You will also wear a protective eye shield at night, which you should continue to wear until your doctor instructs you to remove it.

It is important to follow all instructions given to you by your physician, as this helps bring the fastest visual recovery. Plan to take it easy after your cornea transplant, and slowly work your way back to your normal activities.

Corneal transplantation surgery has a high success rate, but like any surgery complications can occur. The most common complication is rejection of the new cornea. This problem can be recognized by increased sensitivity to light and a sudden increase in eye pain. Because rejection of the new donor tissue can take place years after having surgery, it’s important to schedule and attend follow-up appointments based on your doctors instructions as well as remaining on any post-operative drops prescribed to you by your physician.
