Retrocorneal ridges after anterior posterior radial keratotomy (Sato's operation) in a patient with retinitis pigmentosa.

A 51-year-old man with bilateral cataracts and retinitis pigmentosa had decreased visual acuity. He also had retrocorneal ridges OU. The patient had undergone anterior posterior radial keratotomy (Sato's operation) OU at age 14 years. We believe that the retrocorneal ridges in our patient, which were found after Sato's operation, may be rare.
