PURPOSE: To evaluate the efficacy of excimer laser phototherapeutic keratectomy (PTK) in treating the Schnyder cristalline corneal dystrophy. METHODS: We examined the members of three generations of a family affected by Schnyder crystalline dystrophy. Two patients with disabling visual acuity were treated with PTK. RESULTS: The best corrected visual acuity (BCVA) of the patient with the cristalline form of the dystrophy progressed from 20/70 to 20/25. The BCVA of the other patient affected by the sine crystals form of the Schnyder dystrophy progressed from 20/70 to 20/30. CONCLUSIONS: Excimer laser photokeratectomy is a valuable tool in treating the Schnyder cristalline form of corneal dystrophy.
