摘要
目的比较波前像差引导的个性化飞秒激光辅助的准分子激光原位角膜磨镶术(FS-LASIK)与角膜地形图引导的个性化FS-LASIK矫正近视术后的视觉质量。设计回顾性比较性病例系列。研究对象北京同仁医院连续接受FS-LASIK的近视眼患者130例(130眼)。方法波前像差引导的FS-LASIK的近视眼患者68例(68眼)作为波前像差引导组,角膜地形图引导的FS-LASIK的近视眼患者62例(62眼)作为角膜地形图引导组。所有患者术后随访6个月。选取右眼资料进行分析。对两组患者术前及术后6个月的随访资料进行比较。主要指标视力、全眼高阶像差、对比敏感度。结果术后6个月裸眼视力达到或超过术前最佳矫正视力者波前像差引导组占94.1%,角膜地形图引导组占95.2%(χ^(2)=0.069,P>0.05)。术后6个月两组总高阶像差的均方根值,彗差、三叶草像差及四阶球差的增加量差异均无统计学意义(P均>0.05);两组间各空间频率的对比敏感度(LogCS值)差异亦无统计学意义(P均>0.05)。结论波前像差引导的个性化FS-LASIK与角膜地形图引导的个性化FS-LASIK术后均可获得良好视力及视觉质量。
Objective To compare the visual quality between wavefront-guided ablation and topography-guided ablation in femtosecond laser-assisted in situ keratomileusis(FS-LASIK)for myopia.Design Retrospective case series.Participants 130 myopia patients(130 eyes)received FS-LASIK in Beijing Tongren Hospital.Methods 68 myopic patients underwent wavefront-guided customized FS-LASIK(wavefront-guided group)and 62 myopic patients underwent topography-guided FS-LASIK(topography-guided group)were reviewed.Only the right eye data from each patient was analyzed.Visual quality outcomes preoperatively and 6 months postoperatively were compared between groups.Main Outcome Measures Visual acuity,higher order aberrations(HOAs)and contrast sensitivity(CS).Results The uncorrected visual acuity(UCVA)levels after surgery reached or superior to the preoperative best corrected visual acuity(BCVA)were in 94.1%patients in the wavefront-guided group and in 95.2%patients in the topography-guided group 6 months after surgery,respectively(χ^(2)=0.069,P>0.05).There is no significant difference in Log contrast sensitivity(LogCS)values between groups(all P>0.05).There are no significant differences in the amount of changes in the higher order aberrations between the two groups(all P>0.05).Conclusion Both wavefront aberration guided FS-LASIK and corneal topography guided FS-LASIK can obtain good visual acuity and visual quality after surgery.
