Corneal transplantation (keratoplasty) is a surgical procedure to replace part of your cornea with corneal tissue by the donor. The cornea of the eye is the transparent surface of your eye. This is where the light enters your eyes.
Most corneal transplants are successful. But corneal transplantation carries a small risk of complications such as corneal rejection.
Anatomy of the eye
Corneal transplantation is often used to restore vision to a person with a damaged cornea.
Corneal transplant requirements:
- Protruding cornea (keratoconus)
- Fox dystrophy, an inherited disease
- Thinning or rupture of the cornea
- Corneal scarring, caused by infection or injury
- Corneal swelling
- Corneal ulcers do not respond to medical treatment
- Complications of previous eye surgery
Most people who have a corneal transplant have at least some improvement in their vision.
Postoperative vision correction
By adjusting your eyes to the new cornea, your vision may initially be worse than it was before surgery. It may take several months for your vision to improve.
Correction of corneal roughness (astigmatism). Sutures that hold the cornea in place over your eyes may cause your cornea to sag or bulge, resulting in blurred vision. Your doctor may correct some of these by loosening some stitches and tightening them.
Correction of vision problems. Refractive errors such as myopia and farsightedness can be corrected with glasses, contact lenses or in some cases with laser eye surgery.
