Information for the public
Although there is evidence that implantation of a corneal graft–keratoprosthesis works well, a high number of serious complications were reported. NICE has decided that the procedure can be offered on the NHS to people with severe corneal opacity in wet blinking eyes because there are few options for people with this condition if a standard corneal transplant has failed or isn't appropriate.
Your health professional should fully explain what is involved in having this procedure, and discuss the possible benefits and risks with you. There are risks of serious complications and your sight may get worse. You will also need to have regular checks in the long term, and some people find this to be a problem. You should be provided with information in an appropriate format, and told how to find more information about the procedure. All of this should happen before you decide whether you want to have this procedure or not.
NICE said that the procedure should only be done in people who have inadequate sight in both eyes. It also said that the procedure is usually only offered after a standard corneal transplant has failed.
NICE noted that there have been a lot of complications reported with the procedure, including loss of remaining sight. But, NICE felt that there are few alternatives for people with this condition, and the possible benefits may outweigh the risks.
