Cornea Transplant

What is a Cornea Transplant?

A cornea transplant, also known as keratoplasty, is a surgical procedure to replace a damaged or diseased cornea with a healthy donor cornea. The cornea is the clear, dome-shaped surface at the front of the eye that plays a crucial role in focusing light for vision. Conditions like keratoconus, corneal scarring, or infections may necessitate this procedure to restore vision or alleviate pain.

How is a Cornea Transplant Performed?

Cornea transplants are typically performed as outpatient procedures and include the following steps:

1. Preparation: The eye is numbed with local anesthesia, and the patient may receive medication to relax.
2. Removal: The damaged cornea is carefully removed using specialized surgical instruments.
3. Replacement: The donor cornea is precisely shaped and sutured into place.
4. Closure: The surgeon uses fine sutures to secure the transplant.

The procedure usually takes 1-2 hours. Different techniques, such as full-thickness (penetrating keratoplasty) or partial-thickness (lamellar keratoplasty), may be used based on the patient’s condition.

What to Expect During the Procedure

The surgery is painless due to anesthesia. After the procedure, the eye is covered with a protective shield, and patients are monitored for a short period before being discharged. Vision improvement is gradual and may take several months as the eye heals.

The Importance of Cornea Transplants in Healthcare

Cornea transplants are vital for restoring vision in patients with severe corneal damage. They provide a life-changing opportunity to regain functional eyesight, alleviate pain, and improve the overall quality of life. With advancements in surgical techniques, the success rate of cornea transplants is over 90%.
