To evaluate the outcomes, recurrances and clinical changes in the treatment of epithelial basement membrane dystrophy (EBMD) and Salzmann's nodular corneal dystrophy (SNCD) patients with phototherapeutic keratectomy (PTK)
A cross-sectional, clinic-based study was performed.125 eyes of 101 patients diagnosed with EBMD or SNCD who underwent PTK between 2000 and 2012 at our institution. Preoperative and Postoperative records were reviewed. Symptoms, clinical findings, uncorrected and corrected visual acuity were collected.
Mean follow-up time was 13 months. Among patients treated for EBMD 71% had improved visual acuity, 9% had the same acuity, 20% had poorer acuity and 89% had resolution of clinical findings and symptoms at the time of follow up. Among the SNCD group 42% had improved visual acuity, 24% had the same acuity, 14% had poorer acuity and 83% had resolution of clinical findings and symptoms at the time of follow up. 17% in the SNCD and 31% in the EBMD group required repeat PTK
PTK is an effective for both EBMD and Salzmann's nodular corneal dystrophy. The relationship between the postoperative clinical improvement, corneal morphologic features and PTK method requires further investigation.
