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 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
- Swelling or detachment of the retina
- Corneal scars
