摘要:
目的　观察ＬＡＳＩＫ术后远期的角膜高阶像差变化及对日常生活中视觉功能的影响。方法　对６７例（１３４眼）接受非球面切削程序引导的ＬＡＳＩＫ的患者随访４ａ。收集术前及术后６个月、４ａ患者的视力、角膜地形图、球差和彗差资料，并由同一名医师完成患者术后视觉功能的评价。结果　术后４ａ随访中无一例患者最佳矫正视力较术前视力下降；术后６个月和４ａ的有效性指数、安全性指数分别达１．０８±０．１６、１．１１±０．１７和１．１２±０．１６、１．１３±０．１４。不管是术后６个月还是４ａ的角膜球差和彗差均较术前显著增加，但术后两个时间点间角膜像差的差异均无统计学意义（均为Ｐ＞０．０５）。大部分患者对日常生活中的各项视觉功能感到满意或很满意（９４．３％、９２．４％）。术后４ａ随访中有７．４％患者诉夜间开车困难。进一步分析视觉功能评分与角膜像差的关系，发现夜间开车困难与角膜球差呈负相关（术后６个月：ｒ＝－０．６６，Ｐ＝０．０４０；术后４ａ：ｒ＝－０．６９，Ｐ＝０．０３９），而且并没有随时间延长而显著改善。结论　近视患者ＬＡＳＩＫ术后有远期稳定的角膜像差和日常生活中的视觉功能感受。
Abstract:
Objective To report the changes of corneal higher-order aberrations and daily visual functions of myopic patients after laser in situ keratomileusis ( LASIK) . Methods A total of 67 patients ( 134 eyes) who underwent LASIK guided by aspherical ablation were included in the study , all cases were followed up for 4 years. The vision . corneal spherical aberration ( SphA) and coma were recorded before LASIK and at 6 months and 4 years after LASIK. The evaluation of the questionnaire about visual functions was performed by the same physician after LASIK. Results The best corrected visual acuity in no eye decreased in 4 years follow-up. The effect index and safety index at 6 months and 4 years after LASIK were l. 08 + 0. 16, 1. 11 +0. 17 and l. 12 +0. 16. 1. 13 +0. 14 , respectively. After LASIK, the corneal SphA and coma were significantly increased,however the difference between 6 months and 4 years after LASIK was not statistically sigruficant ( all P > 0. 05 ) . Most patients felt satisfaction ( 94. 3% ) or very satisfaction (92. 4% ) about the ability to perform each visual function after LASIK. Meanwhile , there was still about 7. 4% patients complained that they could not drive at rught. Further study found that the score of driving at night was negative correlation with corneal SphA ( At 6 months :r = - 0. 66 .P = 0. 040 ;At 4 years :r = - 0. 69 .P = 0. 039) . Conclusion The myopic patients have the long-term stable corneal aberration and satisfaction of daily visual functions after LASIK.
