Figures & data
Figure 1 Case 1 was complicated by a shallow anterior chamber (A) because of bleb leakage with Seidel’s phenomenon (B). After corneal lamellar grafting, the anterior chamber had kept deep (C) and the IOP had also increased.
Figure 2 Using a corneal trephine (5.5 mm diameter), half-layered corneoscleral tissues was dissected away (A). Clean, healthy edges of the dissection were regularized (B). Then a donor’s lamellar, round, preserved corneal piece with 5.5 mm diameter and 0.8 mm thickness was placed (C) and was sutured exactly to the patient’s corneoscleral area with 10-0 nylon (D).
Figure 3 Case 3 had a giant ischemic bleb (A) and hypotony after MMC trabeculectomy. His left fundus showed typical hypotony maculopathy (B). After corneal lamellar grafting, the anterior chamber had remained deep (C) and the IOP had increased because of complete closure of the scleral cleft (D).
