Excimer Laser Phototherapeutic Keratectomy for the Treatment of Silicone Oil-Induced Band-Shaped Keratopathy

Abstract

PURPOSE: To study the efficacy of excimer laser phototherapeutic keratectomy (PTK) for the treatment of band-shaped keratopathy (BSK). METHODS: A retrospective analysis of case records of 20 eyes of 20 patients with silicone oil-induced BSK and significant media haze that underwent PTK was conducted. Improvement in corneal clarity and best-corrected visual acuity (BCVA) was assessed at 6 weeks postoperatively. RESULTS: The mean ablation depth was 62.63±23.82 μm (range 25 to 100 μm). Postoperative course was uneventful, and the mean time for healing of the epithelial defect was 4.25±2.43 days. All the eyes showed significant improvement in corneal clarity at 6 weeks postoperatively. The mean ..
