Thirty-three eyes with different corneal dystrophies underwent phototherapeutic keratectomy to ablate corneal opacities, surface irregularities and corneal wounds. For most patients the treatment goal was to improve vision but also corneal woundhealing, glare problems and unstable refraction were indications for treatment. In 27 eyes with the treatment goal to improve vision, 23 improved 2 lines or more on the visual chart used. In none of the patients has the treatment led to a worsening of the condition. The mean follow-up time was 9 months. Excimer laser ablation of corneal dystrophies seems to be a good treatment, which can improve visual functions considerably, heal corneal wounds and in this way postpone corneal grafting in many cases.
33只患有不同角膜营养不良的眼睛接受了光治疗性角膜切削术，以消除角膜混浊、表面不规则和角膜伤口。对于大多数患者来说，治疗目标是提高视力，但角膜伤口愈合、眩光问题和屈光不稳定也是治疗的指征。在27只以提高视力为治疗目标的眼睛中，23只在使用的视力表上提高了2行或更多。没有一位患者的病情因治疗而恶化。平均随访时间为9个月。准分子激光消融角膜营养不良似乎是一种很好的治疗方法，它可以显著改善视觉功能，愈合角膜伤口，从而在许多情况下推迟角膜移植。
