A simple technique for managing eyelid retraction in a patient with an exposed Boston type 2 keratoprosthesis (Kpro)
Reviewed by Konal Saha

The article describes a patient with mucous membrane pemphigoid and a Boston type 2 Kpro. In the early postoperative period (one week) inferior skin retraction was noted with exposure of the Kpro and carrier cornea. The exposure was managed by fashioning a disc of porous polyethylene to surround the Kpro optic. This disc was positioned under the surrounding eyelid tissue which was advanced around the optic using a purse string suture. The intervention was successful with no further treatment of the exposure required at two years follow-up. The technique is appealing due to the immediate visual recovery and lack of any donor site morbidity.
