摘　　要：目的 探讨中国民航飞行学员行角膜屈光手术后的裸眼远视力水平及其稳定性. 方法 收集164名在中国民航飞行学院体检获得Ⅰ级体检合格证、有角膜屈光手术史的飞行学员术后3年裸眼远视力测量值及其手术年份和方式.采用描述性统计和重复测量资料方差分析的方法分析裸眼远视力的术后3年变化情况. 结果 中国民航飞行学院飞行学员行角膜屈光手术后第3年有93.90％的裸眼远视力≥1.0,不同手术方式的术后3年裸眼远视力较为稳定（平均水平均≥1.0）;术后第3年裸眼远视力＜1.0的眼有20只,其中11只眼术后第1年远视力即＜1.0,9只眼相对第1年远视力下降＞0.1. 结论 角膜屈光手术对飞行学员的远视力矫正水平高,稳定性和安全性较好.后期研究应增加调查视觉质量指标并关注座舱环境对术后视功能的影响.Objective To explore the effect of corneal refractive surgery and the stability of naked distant vision in the treated civil flying cadets.Methods The naked distant vision,time and method of corneal refractive surgery in 164 flying cadets,who had received the surgery for at least 3 years and acquired Class Ⅰ medical certificate in the physical examination of Civil Aviation Flight University of China,were collected and analyzed.Statistical description and repeated measurement data analysis of variance were used to analyze the change of naked distant vision in the 3 years.Results 93.90% civil flying cadets＆#39; naked distant vision values were above 1.0 in the 3rd year after the corneal refractive surgery.The naked distant vision that corrected by different surgical method was stable （average level was higher than 1.0）.There were 20 eyes＆#39; naked distant vision 〈1.0 in the 3rd year after surgery,11 of which were 〈1.0 in the 1st year and 9 eyes＆#39; dropped amplitude 〉0.1 as compared with that in the 1st year.Conclusions The effect of corneal refractive surgery is satisfied and the treated flying cadets obtain stable distant vision.More visual quality indicators are suggested and the influence of flying environment on post-surgery visiual function should be studied in further.
