OBJECTIVE: To emphasize the effectiveness of phototherapeutic keratectomy (PTK) in a patient with Schnyder crystalline corneal dystrophy (SCCD). METHODS: Case report. RESULTS: Two eyes of a patient with SCCD underwent PTK. Best corrected visual acuity (BCVA) increased from 2/10 to 8/10 (plano/-1.50 x 10) in the right eye in a lit room. BCVA of the left eye was 4/10 (-8.00/-1.50 x 170) and did not change after treatment because of anisometropic amblyopia. No recurrence was detected after 68 months of follow-up. CONCLUSION: PTK may be effective in the treatment of SCCD, especially if the crystals are the cause of visual disturbance.
