Cornea Transplant Procedure

A circular disk-shaped section of your cornea is removed during a full-thickness cornea transplant (penetrating keratoplasty) and replaced with a donor corneal piece of a similar size. A cornea transplant (also known as a keratoplasty) involves surgery to replace a portion of your own cornea with donor corneal tissue.

  1. Cornea Transplant Procedure

  2. What is Cornea Transplant? • A cornea transplant (keratoplasty) is a surgical procedure that involves replacing part of your cornea with corneal tissue from a donor. Your cornea is a transparent, dome-shaped surface of your eye. It is where light enters your eye and is a large part of your eye's ability to see clearly. • A cornea transplant could restore vision, reduce pain, and improve the appearance of a damaged or diseased cornea. • Most cornea transplant procedures are successfully completed. But cornea transplant carries a small risk of complications, like the rejection of the donor cornea.

  3. Why it is done • A cornea transplant is most frequently used to restore vision to a person with a damaged cornea. A cornea transplant could also relieve pain or other signs and symptoms related to cornea diseases. • A number of conditions could be treated with a cornea transplant, including: • A cornea that bulges outward (keratoconus) • Fuchs' dystrophy, a hereditary condition • Thinning or tearing of the cornea • Cornea scarring, caused by infection or injury • Swelling of the cornea • Corneal ulcers not responding to medical treatment • Complications caused by previous eye surgery

  4. Risk • The cornea transplant is relatively safe. Still, it does carry a small risk of severe complications, such as: • Eye infection • Pressure increases within the eyeball (glaucoma) • Issues with the stitches used to secure the donor cornea • Rejection of the donor cornea • Bleeding • Retinal problems, like retinal detachment or swelling

  5. How you prepare • Before cornea transplant surgery, you will undergo: • A thorough eye examination - Your eye doctor looks for conditions that may cause complications after surgery. • Measurements of your eye - Your eye doctor determines what size donor cornea you require. • A review of all medications and supplements you are taking - You might need to stop taking specific medications or supplements before or after your cornea transplant. • Treatment for other eye problems - Unrelated eye problems, like infection or inflammation, could reduce your chances of a successful cornea transplant. Your eye doctor will treat those problems prior to your surgery.

  6. What you can expect During the procedure • On the day of your cornea transplant, you will either be given a sedative to help you relax and a local anesthetic to numb your eye, or you will be put to sleep. No matter what, you should not feel pain. • The surgery is done on one eye at a time. The amount of time spent in surgery is different and depends upon your situation.

  7. What you can expect After the procedure • Once your cornea transplant is completed, you could expect to: • Receive medications -Eyedrops and, at times, oral medications immediately after cornea transplant and during recovery will help control infection, swelling, and pain. Eyedrops to suppress the immune system help in preventing cornea rejections. • Wear eye protection -Eyeshields or glasses protect your eye as it recovers. • Lie on your back - Depending on the type of transplant, you may have to do this for a while after surgery to help the new tissue stay in place. • Avoid injury - Plan to take it easy after your cornea transplant, and gradually work your way up to your normal activities, including exercise. Do not rub or squeeze your eye. For the rest of your life, you will need to take extra precautions to avoid harming your eye!

  8. Results • Most people who receive a cornea transplant will have their vision at least partly restored. What you could expect after your cornea transplant depends on the reason for your surgery and your health. • Your risk of complications and cornea rejection persists for years after your cornea transplant. For this reason, consult your eye doctor annually. Cornea rejection could often be managed with medications. • Vision correction after surgery • Your vision may initially be worse than prior to your surgery as your eye adjusts to the new cornea. It could take several months for your vision to improve.

  9. Results • Once the outer layer of your cornea has healed — several weeks to several months after surgery — your eye doctor will work to make adjustments that could improve your vision, such as: • Correcting unevenness in your cornea (astigmatism) - The stitches that keep the donor cornea in place on your eye may cause dips and bumps in your cornea, making your vision blurry in spots. Your doctor may correct some of this by releasing some stitches and tightening others. • Correcting vision problems - Refractive errors, like near-sightedness and farsightedness, could be corrected with glasses, contact lenses, or, in some cases, laser eye surgery.
