【摘要】目的:探讨智慧型光斑LASIK治疗近视或近视散光可预测性、稳定性、有效性及术后残留屈光度危险因素分析。方法:回顾性分析200810/200910在我中心行LASIK病例,术前最佳矫正视力(BCVA)≥,随访时间>1mo,球镜<,共768例。按激光切削模式及屈光度分组,对术后裸眼视力,术后1,3,6mo;1a残留等效球镜,屈光回退患者术前术后数据行统计学分析。结果:10例BCVA术后未达术前;预测性:%SE<,%SE<;%SE<,%SE<;术后残留屈光度,常规组:1mo:±;3mo:±;6mo:±;1a:±。波前组:1mo:±;3mo:±;6mo:±;1a:±;视力改变,常规组:0±,波前组:±。23例术后残留屈光度危险因素分析,术后残留球镜与年龄,术前球镜有关,术后球镜=+;术后残留柱镜与术前柱镜,术前中央角膜厚度有关,术后柱镜=+。结论:智慧型光斑LASIK预测性,稳定性,有效性均较好,波前像差引导LASIK在预测性及有效性方面更优,两种术式均有较好的稳定性;术后残留球镜危险因素:年龄、术前球镜,术后残留柱镜危险因素:术前柱镜、术前中央角膜厚度。

Abstract AIM: To evaluate the predictability, stability, efficacy of laser in situ keratomileusis (LASIK) using varied size spot laser for the treatment of myopia pound myopic astigmatism. And analyse risk factors in residual refraction after : A total of 768 samples (eyes) were enrolled in this retrospective study in our surgery center from Oct. 2008 to Oct. 2009. The inclusion criteria were spherical equivalent (SE) no more than , followup periods more than one month and BCVA no less than . The samples were divided by surgery mode and power of SE. The uncorrected visual acuity (UCVA), residual refraction of one month, three months, six months, one a after surgery and the preoperative and postoperative data of regression samples were used for : Ten samples lost the BCVA; % samples were within of emmetropia and % of the samples were within of conventional LASIK(conventional group), % and % of wavefrontguided LASIK(wavefrontguided group) respectively; the residual refraction was ± at one month, ± at three months, ± at six months, ± at one year postoperatively in conventional group and the re
