摘　　要：目的评价Zywave波前像差仪在激光原位角膜磨镶术（LASIK）前测量屈光度的作用。方法随机选取2011年6月至2011年8月在我院接受LASIK术前检查近视46例（84眼）。应用电脑验光、检影验光、主觉验光、综合验光及Zywave波前像差仪对其球镜度、柱镜度及等效球镜度测量并行统计分析。结果低度近视组电脑验光与波前像差仪验光球镜度、等效球镜度间差异有统计学意义，柱镜度间差异无统计学意义，综合验光、主觉验光分别与波前像差仪验光比较，3种屈光度之间差异均无统计学意义，检影验光与波前像差仪验光的3种屈光度之间差异均有统计学意义。中度近视组及高度近视组常规验光分别与波前像差仪验光比较，柱镜度间差异有统计学意义，其余差异无统计学意义。结论应用Zywave波前像差仪对LASIK术前屈光度测量有一定准确性。对中高度近视波前像差仪验光与其他验光存在差异，可以此对综合验光与主觉验光进行细微调整。Objective To evaluate the effect of Zywave aberrometer in measuring refraction before laser in situ keratomileusis （LASIK）. Methods Zywave aberrometer and common refraction methods were used respectively to measure the refractive errors in 84 eyes of 46 patients. The sphere, cylinder and spherical e- quivalent refraction results of each method were analyzed by the statistic software. Results In low myopia group, the difference of the sphere and spherical equivalent refractions measured by auto-refraction and Zy- wave aberrometer was statistically significant. The sphere, cylinder and spherical equivalent refractions meas- ured by optometry, manifest refraction and Zywave aberrometer had no statistical difference, there was signif- icant difference in the three refractions measured by retinoscopy and Zywave aberrometer. In moderate and high myopia group, the cylinder refractions measured by these methods were statistically significantly differ- ent,other refractions had no statistical difference. Conclusions Zywave aberrometer is accurate in refrac- tive measurement.
