Corneal Transplant
Understanding Corneal Transplants
The cornea is the clear, dome-shaped surface that covers the front of the eye. It plays a crucial role in focusing vision and protecting the eye from harmful particles and bacteria. A corneal transplant, also known as keratoplasty, involves replacing a damaged or diseased cornea with healthy tissue from a donor.
When Does Surgery Become Necessary
Corneal transplants become necessary when the cornea becomes cloudy or distorted due to conditions such as keratoconus, corneal scarring from infections or injuries, or complications from previous eye surgeries. These conditions can significantly affect vision and, in severe cases, can lead to blindness. A corneal transplant is often recommended when less invasive treatments, such as eyeglasses or contact lenses, are no longer effective.
Overview of the Surgical Procedure
During a corneal transplant, the surgeon removes a portion of the patient's cornea and replaces it with a donor cornea. The new cornea is then stitched into place. The primary objective of the procedure is to restore vision and improve the quality of life for the patient.

Pre-surgery Procedures and Checks
On the day of the surgery, the patient's eye will be numbed with local anesthesia, and the area around the eye will be cleaned to prevent infection.

- The patient's eye is numbed with local anesthesia.
- The surgeon removes a portion of the patient's cornea.
- The donor cornea is placed in the eye.
- The new cornea is stitched into place. ### Postoperative Care After the surgery, the patient's eye will be covered with a protective shield. The patient will need to use medicated eye drops to prevent infection and inflammation and will need to attend regular follow-up appointments to monitor healing. ### Recovery and Rehabilitation Recovery from a corneal transplant can take several months. During this time, patients may need to wear eyeglasses or a protective shield and avoid strenuous activities. Vision should gradually improve as the eye heals. ## References
