The value of corneal topography guided LASEK operation in the treatment of patients with high myopia

目的探讨角膜地形图引导的LASEK术在高度近视患者治疗中的价值。方法选择该院2011-01～2012-07收治的高度近视患者60例为研究对象,随机分为观察组与对照组,观察组患者使用角膜地形图引导的LASEK术进行校正,观察组使用普通LASEK手术,比较两组患者术后裸眼视力、剩余屈光度及不良事件报告率之间的差异。结果使用角膜地形图引导的LASEK术的观察组患者在术后裸眼视力方面与对照组比较差异无统计学意义(P>0.05),剩余屈光度小于对照组(P<0.01),不良事件报告率低于对照组(P<0.05)。结论角膜地形图引导的LASEK术在治疗高度近视患者中效果更好、更安全,具有重要的临床应用价值。

Objective To study the value of corneal topography guided LASEK operation in the treatment of patients with high myopia.Methods Sixty patients with high myopia treated in our hospital from 2011 January to 2012 July were used as the object of investigation.These patients were randomly separated into two groups： control group and observation group.The patients in the observation group were corrected vision by using corneal topography guided LASEK operation,and the control group received ordinary LASEK operation,and the differences in postoperative uncorrected visual acuity,residual diopter and adverse event reporting rate were compared between two groups.Results There was no statistically signicant differences in vision acuity after operation between two groups（P＆gt;0.05）.But there was a statistically difference in residual diopter and adverse event reporting rate between two groups（P＆lt;0.05 or P＆lt;0.01）.Conclusion Corneal topography guided LASEK operation in the treatment of patients with high myopia shows good efficacy and safety,and it has an important value in clinical applitation.
