LASIK治疗近视散光临床分析

A preliminary study of laser in situ keratomileusis for correction of myopic astigmatism

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。

Objective,To evaluate the therapectic effects of laser in siut keratomileusis(LASIK)for correction of myopic astigmatism.Methods:According to the preoperative astigmatism,72 eyes were divided into groupA(no astigmatism),B(astigmatism lower than 2D)and C(astigmatism greater than 2D).The preoperative spherical equivalent refraction is not statistical(P>0 05),the refraction ranged from-2 25 to -10 0D,and treated lasik.Follow-up periods after lasik were 8 13±1 70months.Comparative analysis was used to calculate the surgical effects.Results:The mean preoperative astigmatism was 1 37±0 39D and 2 99±0 82D,the post-operative astigmatism was 0 19±0 57D and 0 34±0 46D,the preoperative and post-operative astigmatic axes was 4 9°±2 2° and 3 7°±2 5° in group B and C.Conclusion:The correction of astigmatism with lasik is accurate,effective and safe.
