摘　　要：目的:探讨近视患者飞秒制瓣准分子激光术后视力改善情况及其影响因素。方法:收集2010年1月至2013年12月期间,我院收治的近视患者72例(129眼),采用飞秒制瓣准分子激光术治疗,观察术后视力改善情况,并分析其影响因素。结果:患者的术后远视力(VA)、近视力(NVA)及最佳矫正视力(BCVA)均较术前显著提高(P<0.05);Logistic回归分析显示,术前BCVA、NVA、眼轴长度、切削比、眼轴长度以及术后视近时间均是术后视力的影响因素(P<0.05)。结论:飞秒制瓣准分子激光术治疗近视具有显著疗效,术后视力受术前BCVA、NVA、切削比、眼轴长度以及术后视近时间等的影响。Objective To investigate the visual acuity improvement and related factors for myopia after femtosecond flap excimer laser surgery. Methods 72 myopic patients （129 eyes） in our hospital between January 2010 and December 2013 were chosen. The patients all received femtosecond flap excimer laser surgery. The visual acuity improvement after surgery was observed, and the influencing factors were analyzed. Results The distance vision （VA）, near vision （NVA） and best corrected visual acuity （BCVA） significantly increased before surgery （P〈0.05）. Logistic regression analysis showed that preoperative BCVA, NVA, axial length, cutting ratio, axial length and time of near vision were the affecting factors of visual acuity （P〈0.05）. Conclusion Femtosecond flap excimer laser surgery for myopia has significant effect , but the preoperative visual acuity was affected by BCVA , NVA, cutting ratio, axial length and time of near vision.
