Photorefractive keratectomy (PRK) using the Summit emphasis erodible mask was performed on 229 eyes with myopic astigmatism. To analyze the efficacy and safety of the method, we evaluated the following: spectacle corrected visual acuity and refractive error as parameters of efficacy; corneal clarity, decentration of the ablation zone and complications as parameters of safety. Despite the short follow up (the longest was 12 months) our results show that the emphasis erodible mask appears to be an effective surgical method for correcting myopic astigmatism. However, we found a great number of complications and subjective symptoms that worsened the visual outcome. We conclude that the emphasis erodible mask has satisfactory efficacy but unsatisfactory safety.
对229只患有近视散光的眼睛实施了使用Summit公司的可蚀性掩膜的准分子激光角膜切削术（PRK）。为分析该方法的有效性和安全性，我们评估了以下内容：将矫正视力和屈光不正作为有效性参数；将角膜清晰度、切削区偏心以及并发症作为安全性参数。尽管随访时间较短（最长为12个月），但我们的结果表明，可蚀性掩膜似乎是一种矫正近视散光的有效手术方法。然而，我们发现大量并发症和主观症状使视觉效果变差。我们得出结论，可蚀性掩膜有令人满意的有效性，但安全性不尽人意。
