Abstract. Purpose:We evaluated the treatment outcome of phototherapeutic keratectomy(PTK)for corneal dystrophy. Cases:This study included 31 eyes of 16 patients who was thought clinically granular corneal dystrophy and underwent PTK for corneal dystrophy presenting with diffuse opacity in the superficial corneal stroma with a minimum follow-up of 6 months. The mean age at surgery was 67.3±10.6 years. The mean follow-up period was 26.0±25.0 months. Findings:Best corrected visual acuity improved by 2 lines or more in 23 eyes of 31 eyes(74%)of cases. A hyperopic shift of +0.72D was observed 6 months after surgery. Contrast sensitivity in average improved postoperatively. Conclusion:These results suggest that PTK is an effective treatment for diseases in the superficial corneal stroma.
