Active Pedicle Epithelial Flap Transposition Combined with Amniotic Membrane Transplantation for Treatment of Nonhealing Corneal Ulcers

Figure 2

Slit-lamp photographs showing the treatment course of nonhealing corneal ulcers. (a) Patient 1: the preoperative uncorrected visual acuity was finger counting. The size of the ulcer was approximately 4.0 × 3.0 mm. The surrounding tissue displayed infiltration and edema. (b) At 1 month after surgery, the corneal ulcer was completely cured, with the relief of corneal opacity, and the postoperative uncorrected visual acuity was 0.1 (1.0 log MAR). (c) Patient 2: the preoperative uncorrected visual acuity was hand motion. The ulcer was approximately 5.0 × 2.5 mm. Evident stromal necrosis, edema, and anterior chamber hypopyon were observed. (d) At 1 month after surgery, the corneal ulcer was healed, with the relief of corneal edema, and the postoperative uncorrected visual acuity was 0.1 (1.0 log MAR).
