Fig. 5. Examples of complications. A. Significant necrosis and melt of corneal tissue between the plates. If not repaired, this can rapidly lead to aqueous leak and subsequent endophthalmitis. B. Skin overgrowth around a type II keratoprosthesis. The excess skin can be trimmed away quite easily. C. Tear fistula in a patient with a type II keratoprosthesis. (Courtesy of Dr. Claes H.
