Abstract
We performed a phototherapeutic keratectomy using excimer laser 193-nm ablation in a patient with granular dystrophy of the cornea. The hyperopic shift caused by the 5-mm diameter tissue ablation could effectively be corrected by a high oxygen-transmissible, aspheric, rigid contact lenses 1 week after treatment. Corneal topographic analysis was used to monitor the changes in corneal shape after excimer treatment. The 3.5-D hyperopic shift did not change after 4 months, but corneal shape altered during this period. It was not necessary to adjust lens parameters. The central corneal area was clear, and visual acuity improved from 20/40 to 20/20.
