Doctors use a variety of tools to operate on patients, such as alligator forceps, ophthalmic cannulas and needle holders. Eye scissors are also used in cornea transplant. The cornea transplant is a surgical procedure in which the donor's corneal tissue is used to replace part of the cornea. Your cornea is a transparent, dome shaped surface of the eye that accounts for a large part of your eye's ability to focus.


Cornea transplant can restore vision, reduce pain, and improve the appearance of damaged or diseased corneas. Most cornea transplant procedures are successful. However, cornea transplant carries a small risk of complications, such as rejection of the donor cornea.



The Role of Cornea transplant

Cornea transplant is most commonly used to restore vision in patients with corneal damage. Cornea transplant can also relieve pain or other symptoms and signs associated with corneal diseases. Cornea transplant can treat many conditions, including keratoconus, corneal thinning, corneal scarring, corneal opacity, corneal swelling and complications caused by previous ophthalmic operations.



Risk of Cornea Transplant

Although cornea transplant is a relatively safe procedure, it still poses certain risks, such as eye infection, cataract, glaucoma, problems with the stitches used to secure the donor cornea, and corneal swelling.



Signs and Symptoms of Cornea Rejection

In some cases, your body's immune system may mistakenly attack the donor's cornea. This is called rejection and may require medication or another cornea transplant. If you find that you have any of the following symptoms, you need to contact your doctor immediately. Here are some common rejection reactions, such as vision loss, eye pain, eye redness, and sensitivity to light. About 10% of patients will have rejection after cornea transplant.

How You Prepare

Before cornea transplant surgery, you will undergo a thorough eye exam. Your eye doctor looks for conditions that may cause complications after surgery. Your doctor will also measure your eyes to determine the size of the cornea you need. You also need to tell your doctor if you are taking certain medications recently, and you may need to stop taking them before and after surgery. In addition, the doctor will work to treat other problems before your surgery, such as infection or inflammation, may reduce your chances of a successful cornea transplant. Your eye doctor will work to treat those problems before your surgery.


After all these preparations, you need to find a suitable corneal donor. Most of the corneas used for cornea transplant come from deceased donors. Unlike organs such as liver and kidney, people who need a corneal transplant usually do not have to wait for a long time. Unless a lot of people's cornea transplant is conditional, because they have more conditions for corneal corneal transplant. The cornea should not be used in donors with a variety of diseases, such as certain central nervous system diseases, infections, previous eye surgery or eye diseases, or deaths from unknown causes.
