摘要:

目的  评价虹膜识别定位下波前像差引导的个体化LASIK治疗近视性散光眼术后波前像差的变化。方法  采用随机对照研究,对接受LASIK治疗近视性散光眼的患者97人采用随机表分为两组,Zyoptix组49人(98眼)采用虹膜识别定位下波前像差引导的个体化LASIK治疗,Planoscan组48人(96眼)采用传统LASIK治疗,采集术前和术后6个月患者视力,屈光度和波前像差数据,比较两种手术对术后眼波前像差的影响。结果  术前两组的球镜度、柱镜度、瞳孔直径6mm区的总体波前像差均方根值(RMS)、高阶像差RMS、三阶彗差三叶草像差和四阶球差RMS差异均无统计学意义(P>0.05)。术后6个月各观察值与术前比较差异有统计学意义(P<0.01)。术后6个月两组间比较柱镜度,瞳孔直径6mm的总体波前像差、总体高阶像差、三叶草像差和四阶球差的RM S,Zyoptix组均小于Planoscan组差异有统计学意义(P<0.05),两组球镜度、瞳孔直径6mm去四阶球差总体高阶像差和三阶彗差RMS值差异无统计学意义(P>0.05)。结论  虹膜识别定位下波前像差引导的个体化LASIK治疗近视性散光眼术后降低波前像差效果要优于传统LASIK手术。

Abstract:

Objective  To evaluate the change of wave-front aberration 6 months after iris-recognition combined with wave-front-guided LASIK and Planoscan-LASIK for myopic astigmatism. Methods  In this prospective contrast study,97 patients (194 eyes) with myopic astigmatism were divided into two groups: the Zyoptix group (49 patients, 98eyes) accepted iris-recognition combined with wave-front-guided LASIK and the  Planoscan group (48 patients, 96 eyes) accepted Planoscan-LASIK. By comparing the collected data of diopter and wave-front aberration of the two groups, the influence of the two kinds of operations on wave-front aberration were studied. Results  The preoperative refraction and wave-front aberration of the  Zyoptix  group and  the  Planoscan group were not significantly different  There were significant differences in refraction and wave-front aberration between the two groups 6 months after operation, but no significant differences were found in the 3rd coma aberration and spherical-degree. Conclusions  Iris-recognition combined with wavefront-guided LASIK for myopic astigmatism is superior to PlanoscanLASIK,
