[Possibilities of therapeutic photokeratotomy with the excimer laser in treatment of Schnyder crystalline corneal dystrophy].
OBJECTIVE
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.
