Figure 2

The procedure of modified small tectonic keratoplasty and conjunctival flap covering. (A and A’) Corneal ulcer after clearing of necrotic tissues and restoring of synechia. (B and B’) A selected trephine was used to mark around the perforation. (C and C’) The recipient bed with the posterior stroma and Descemet’s membrane reserved. (D and D’) The corneal button was placed in the bed and sutured with interrupted 10–0 nylon sutures. (E and E’) A bridge-like conjunctival flap, 0.5 mm larger than the ulcer, was obtained. (F and F’) conjunctival flap was secured tightly using 10–0 monofilament nylon sutures.
