摘　　要：目的比较非球面调整的LASIK手术(Fine Adjustded customized Alation Treatment,F-CAT)与标准LASIK手术(Standard Excimer Laserin Keratomileusis Lasik,S-LASIK)后对比敏感度、眩光敏感度及波前像差的变化,评价非球面调整后的近视手术对视觉质量的影响。方法回顾性分析同期接受F-CAT手术近视患者12例(24只眼)和接受S-LASIK手术患者12例(24只眼),分别观察术前和术后视力、屈光度、对比敏感度、球差,对数据进行统计学分析。结果术后两组裸眼视力均达到术前最佳矫正视力,无显著性差异(P>0.05),术后3月F-CAT组对比敏感度和眩光敏感度与术前相比无下降,术后F-CAT组对比敏感度和眩光好于S-LASIK组,在6c/d,12c/d,18c/d有显著性差异(Wilcoxon,P<0.05);两组术后3月球面像差、高阶像差的均方根值RMS均有所增加,和术前比较均有显著性差异(Wilcoxon,P<0.05),但术后F-CAT组的球面像差、高阶像差的均方根值RMS均低于S-LASIK组,两组之间有显著性差异(Wilcoxon,P<0.05)。结论非球面调整的LASIK手术可以降低术后的球差,改善近视患者对比敏感度及眩光,术后可以获得更好的视觉质量。Objectives to compare the change of sensitivity,glare sensitivity and wavefront aberration after Fine Adjusted Customized Alation Treatment(F-CAT) surgery and Standard Excimer Laser in Keratomileusis Lasik(S-LASIK) surgery;to analyze the influence on vision quality after asphericity adjustment myopia surgery.Methods to analyze retrospectively 12 myopia patients(24 eyes) taking F-CAT surgery and 12 patients(24 eyes) taking S-LASIK at the same period;to statistically analyze the data after observing respectiv...
