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.
我们对一名患有颗粒状角膜营养不良的患者使用准分子激光193纳米消融术进行了光治疗性角膜切除术。治疗1周后，由直径5毫米的组织消融引起的远视偏移可通过高透氧性、非球面、硬性隐形眼镜有效矫正。角膜地形图分析用于监测准分子激光治疗后角膜形状的变化。4个月后3.5屈光度的远视偏移没有改变，但在此期间角膜形状发生了变化。无需调整镜片参数。角膜中央区域清晰，视力从20/40提高到了20/20。
