Postoperative corneal perforation in patient 2. (A) The corneal perforation healed yielding a visual acuity of 20/200 at 6 months after surgery. But a clean, paranasal corneal ulcer, 2 mm in diameter, occurred just beside the conjunctival flap. (B) Both the corneal ulcer and the perforation healed with good survival of the corneal graft and conjunctival flap at 32 months after the second surgery.
