Patient 7 (Mooren’s ulcer, visual acuity: CF, right eye). a Green dotted circle indicates two perforations (1 × 1 mm in diameter) with prolapsed iris; yellow dotted circle indicates a large crescent ulcer at the peripheral region; a pterygium was at the nasal side. b The pterygium was excised, and individualized PK was performed with two thin, penetrating corneal grafts to cover the perforations. A crescent LK graft covered the PK grafts and the ulcerated areas around the perforations, including the region where pterygium was excised. c Green dotted circle indicates a micro-perforation (1.5 months after the surgery), which was cured by the transplantation of a conjunctival flap. d After a follow-up period of 13 months, the graft showed improved transparency
