Corneal transplant
Definition:
A corneal transplant is surgery to replace the clear surface on the front of the eye (the cornea). Alternative Names:
Keratoplasty; Penetrating keratoplasty Text Continues Below
Description:
Most corneal transplant operations are done under local anesthesia on an outpatient basis. This means that the patient is awake but an injection is given to make the eye completely numb. There is no pain. The corneal tissue for transplantation is taken from a donor shortly after death with the permission of the next of kin. Though most transplant procedures carry the risk of rejection of the transplant tissue or organ, the cornea has very limited blood supply, which greatly reduces this risk. Most corneal transplants function extremely well for many years. Indications:
Corneal transplantation is recommended for: - inherited corneal thinning (keratoconus) with visual distortion
- scarring of the cornea from severe infections or injuries
- inherited or acquired corneal clouding (Fuch's dystrophy) with visual loss
