Oral buccal mucous membrane allograft with a corneal lamellar graft for the repair of Boston type 1 keratoprosthesis stromal melts.
OBJECTIVE
To describe a surgical technique to repair Boston type 1 keratoprosthesis (KPro)-related corneal melts.


METHODS
Technique description and review of 3 representative cases.


RESULTS
After harvesting the buccal mucosa from the patient's inner lower lip, the exposed area of the KPro back plate is prepared for repair by adequate exposure and removal of necrotic tissue. The area is then covered with a lamellar patch of cornea secured in place with interrupted 10-0 nylon sutures, followed by a thin layer of buccal mucosa secured in place with interrupted 8-0 vicryl sutures.


CONCLUSIONS
This technique provides surgeons with a method to repair KPro-related corneal melts when there is a conjunctival deficiency.
