The cornea is the clear outer lens on the front of the eye. A corneal transplant is surgery to replace the cornea with tissue from a donor. It is one of the most common transplants done.
You will most likely be awake during the transplant. You will get medicine to relax you. Local anesthesia (numbing medicine) will be injected around your eye to block pain and prevent eye movement during the surgery.
The tissue for your corneal transplant will come from a person (donor) who has recently died. The donated cornea is processed and tested by a local eye bank to make sure it is safe for use in your surgery.
For years, the most common type of corneal transplant was called penetrating keratoplasty.
A newer technique is called lamellar keratoplasty.
A corneal transplant is recommended for people who have:
The body may reject the transplanted tissue. This occurs in about 1 out of 3 patients in the first 5 years. Rejection can sometimes be controlled with steroid eye drops. There have rare cases of graft rejection reported soon after COVID-19 vaccination.
Other risks for a corneal transplant are:
Tell your health care provider about any medical conditions you may have, including allergies. Also tell your provider what medicines you are taking, even drugs, supplements, and herbs you bought without a prescription.
You may need to limit medicines that make it hard for your blood to clot (blood thinners) for 10 days before the surgery. Some of these are aspirin, ibuprofen (Advil, Motrin), and warfarin (Coumadin).
Ask your provider which of your other daily medicines, such as water pills, insulin or pills for diabetes, you should take on the morning of your surgery.
You will need to stop eating and drinking most fluids after midnight the night before your surgery. Most providers will let you have water, apple juice, and plain coffee or tea (without cream or sugar) up to 2 hours before surgery. Do not drink alcohol 24 hours before or after surgery.
On the day of your surgery, wear loose, comfortable clothing. Do not wear any jewelry. Do not put creams, lotions, or makeup on your face or around your eyes.
You will need to have someone drive you home after your surgery.
Note: These are general guidelines. Your surgeon may give you other instructions.
You will go home on the same day as your surgery. Your provider will give you an eye patch to wear for about 1 to 4 days.
Your provider will prescribe eye drops to help your eye heal and prevent infection and rejection.
Your provider will remove the stitches at a follow-up visit. Some stitches may stay in place for as long as a year, or they might not be removed at all.
Full recovery of eyesight may take up to a year. This is because it takes time for the swelling to go down. Most people who have a successful corneal transplant will have good vision for many years. If you have other eye problems, you may still have vision loss from those conditions.
You may need glasses or contact lenses to achieve the best vision. Laser vision correction may be an option if you have nearsightedness, farsightedness, or astigmatism after the transplant has fully healed.
