【摘要】：目的：观察波前像差引导的准分子激光原位角膜磨镶术(laser in situ keratomileusis, LASIK)术后客观指标及主观视觉质量问卷评估,并与常规LASIK做对比,分析波前像差引导的LASIK治疗近视的疗效。 方法：连续选取2009年7月至2010年2月在我院接受波前像差引导的LASIK的近视患者21例(40眼)作为波前组,以及同期接受常规LASIK的近视患者16例(31眼)作为对照组,术后随访1年,术前及术后随访时检查视力、屈光度、高阶像差,并于术后随访时填写主观视觉质量问卷,对两组结果分别进行比较分析。 结果： 1.术后1月两组裸眼视力(uncorrected visual acuity, UCVA)均≥1.0。术后1年所有患者UCVA均≥0.8,其中UCVA≥1.0者波前组97.5%,对照组96.8%,UCVA≥1.5者波前组35.0%,对照组16.1%；较术前最佳矫正视力(best corrected visual acuity, BCVA)提高者,波前组37.5%,对照组19.4%,波前组优于对照组,但差异均无统计学意义(P0.05)； 2.术后两组等效球镜度差异无统计学意义(P0.05),随时间变化两组屈光度仅轻度回退；术后1年时波前组等效球镜度在(+1.0D～-1.0D)和(+0.5D～-0.5D)范围内者所占比分别为75.0%和95.0%,与对照组(分别为77.4%和93.5%)比较差异无统计学意义(P0.05)； 3.术后两组总高阶像差、彗差、球差值均高于术前(P0.05),随时间推移轻度下降。术前两组的总高阶像差、彗差、球差值差异无统计学意义(p0.05)：术后波前组总高阶像差、彗差、球差低于对照组(P0.05)；波前组术后总高阶像差、彗差、球差增加幅度小于对照组(P0.05)； 4.术后主观视觉质量问卷在视力评估方面,白天和傍晚视力两组间差异无统计学意义(P0.05),夜晚和夜晚驾驶视力波前组优于对照组(P0.05),随时间延长各条件下视力评估变化不显著(P0.05)；视觉症状方面,波前组眩光的出现少于对照组(P0.05),光晕、重影、夜晚驾驶困难各项两组间差异无统计学意义(P0.05)；两组光晕随时间延长均明显减轻(P0.05)。 结论：波前像差引导的LASIK与常规LASIK术后均获得良好的裸眼视力；屈光度均基本稳定,可预测性良好；总高阶像差、彗差、球差均较术前增加,随时间推移仅轻度下降；与常规LASIK相比,波前像差引导的LASIK可以减少术后高阶像差的增幅,减少术后眩光的发生,从而改善夜间视觉质量。
[Abstract]:Aim: to observe the objective index and subjective visual quality of wave front aberration guided excimer laser in situ keratomileusis (laser in situ keratomileusis, LASIK) and compare it with conventional LASIK to analyze the efficacy of wavefront aberration guided LASIK in the treatment of myopia. Methods: from July 2009 to February 2010, 21 myopia patients (40 eyes) with LASIK guided by wavefront aberration were selected as wave front group, and 16 myopia patients (31 eyes) who received routine LASIK were selected as control group. The visual acuity, diopter and high-order aberration were examined before and after the follow-up. The subjective visual quality questionnaire was filled out in the follow-up. The results of the two groups were compared and analyzed. Results: 1. One month after operation, the naked visual acuity (uncorrected visual acuity, UCVA) of both groups was 鈮，
