Reasons for ProcedureA corneal transplant can correct vision problems caused by infections, injuries, or medical conditions that effect the cornea. It is often recommended for the following:
- Keratoconus—a thinning and bulging of the cornea that causes blurred vision
- A cornea scarred from infection or injury
- Clouding of the cornea
- Complications of previous eye surgery
Possible ComplicationsThe procedure is usually highly successful. Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Rejection of the new cornea—The body’s defense system attacks the new tissue, damaging it.
- Problems focusing
- Light sensitivity
- Swelling or detachment of the retina
- Corneal scars
