(a) The stromal ulceration was debrided, and the corneal epithelium was removed up to the limbal area. (b) 360  conjunctival peritomy is performed adjacent to limbus. (c) The ulcer was filled up to a surface level with multiple pieces of AM, and a larger AM was transferred to the recipient eye with the epithelial side down. The membrane was trimmed to cover the cornea and limbal area and secured with continuous 10-0 nylon sutures to the conjunctival edges. (d) After suturing, we do a subconjunctival injection with a mixture of dexamethasone and gentamycin. Finally, we place a bandage contact lens to cover the transplanted membrane and cornea.

Following peribulbar and subconjunctival anaesthesia, we carefully debrided the thinner crater and scraped off the corneal epithelium up to the limbal margin followed by a 360  conjunctival peritomy (Figures 1(a) and 1(b)). We secured the membrane under the conjunctival edges with a continuous 10.0 nylon suture (Figure 1(c)). Finally, we applied a subconjunctival injection of a mixture of dexamethasone and gentamycin and placed a bandage contact lens for 2 to 3 weeks (Figure 1(d)).
(a) 3 mm hypopyon formation 2 days after cryopreserved AMT. (b) Regression of hypopyon one week later. (c, d) Clear anterior chamber with healed ocular surface and no signs of inflammation 5 weeks after surgery.

Despite the tested sterility of the ocular surface, the preoperative antibiotic treatment, and the uneventful perioperative period, he developed a 2 mm hypopyon within 48 hours when we reviewed him after primary AMT (Figure 2(a)). The hypopyon resolved completely with the current treatment a week later with no further complications or anterior chamber reaction (Figure 2(b)).
