Interventional procedure overview of nerve graft for corneal denervation
Closed for comments This consultation ended on at Request commenting lead permission
Description:
Blinking helps prevent infection and keeps the eye healthy by spreading a film of tears across the clear layer at the front of the eye (cornea). When nerves to the cornea are damaged (denervation), feeling is lost, and blinking happens less often. This makes the cornea vulnerable to infection and ulcers, which can result in poor vision. In this procedure, under general anaesthesia, one end of a piece of another nerve (the nerve graft) is attached to a healthy nerve, usually above the eye. The other end is passed under the skin and inserted around the damaged cornea. Over several months, new nerve endings grow into the cornea from the graft. The aim is to protect the cornea by improving healing, to reduce infections and the need for eye drops.
