为评价准分子激光原位角膜磨镶术（ＬＡＳＩＫ）治疗近视散光的疗效，对３６例（７２只眼）近视患者按术前散光度数分为３组，Ａ组（无散光），Ｂ组（散光＜２．０Ｄ），Ｃ组（散光＞２．０Ｄ），三组术前等量球镜差异无显著性（Ｐ＞０．０５），范围２．２５～１０．０Ｄ，并用ｌａｓｉｋ对其近视及散光治疗，平均随访时间８．１±１．７个月，对手术前后散光的变化比较分析。结果Ｂ、Ｃ两组术前散光分别为１．３７±０．３９Ｄ和２．９９±０．８２Ｄ，术后７个月残留散光分别为０．１９±０．５７Ｄ和０．３４±０．４６Ｄ，术前、术后散光轴夹角分别为４．９°±２．２°和３．７°±２．５°。结论：ｌａｓｉｋ治疗散光疗效确切，轴向准确，显示出较好的预测性、安全性、稳定性
To evaluate the efficacy of laser in situ keratomileusis (LASIK) for the treatment of myopic astigmatism, 36 cases (72 eyes) of myopia patients were divided into 3 groups according to preoperative astigmatism degree: group A without astigmatism, group B with Astigmatism <2.0D), group C (astigmatism> 2.0D), there was no significant difference between the three groups (P> 0.05), ranging from 2.25 to 10.0D, and lasik Myopia and astigmatism treatment, with an average follow-up time of 8.1 ± 1.7 months, before and after surgery compared changes in astigmatism. Results The preoperative astigmatism of group B and C were 1.37 ± 0.39D and 2.99 ± 0.82D respectively. The residual astigmatism at 7 months after operation was 0.19 ± 0.57D and 0.34 ± 0 respectively. 46D, preoperative and postoperative astigmatism axis angle of 4.9 ° ± 2.2 ° and 3.7 ° ± 2.5 °. Conclusion: lasik astigmatism treatment effect is accurate, axial accuracy, showing good predictability, safety, stability
