EXCIMER-LASER PHOTOTHERAPEUTIC KERATECTOM Y IN TREATING SCHNYDER CRISTALLINE CORNEAL-DYSTROPHY

Purpose To evaluate the efficacy of excimer laser phototherapeutic ker atectomy (PTK) in treating the Schnyder cristalline corneal dystrophy. Methods We examined the members of three generations of a family affe cted by Schnyder crystalline dystrophy. Two patients with disabling vi sual acuity were treated with PTK. Results The best corrected visual a cuity (BCVA) of the patient with the cristalline form of the dystrophy progressed from 20/70 to 20/25. The BCVA of the other patient affecte d by the sine crystals form of the Schnyder dystrophy progressed from 20/70 to 20/30. Conclusions Excimer laser photokeratectomy is a valuab le tool in treating the Schnyder cristalline form of corneal dystrophy .
