目的 评估角膜屈光术后民航飞行员的视觉质量和视功能,探讨角膜屈光手术的安全性和远期稳定性. 方法 对四川大学华西医院眼科就诊的297名飞行员进行视力、屈光度、角膜地形图、对比敏感度、泪膜破裂时间(break-up time,BUT)检查及主观问卷调查.根据等效球镜度(spherical equivalent,SE)分组,屈光正常组:任一眼的SE≤+0.50 D或≥-0.50 D;屈光不正组:任一眼的SE为-0.75～-6.00 D;屈光术后组:有角膜屈光手术史的飞行员.比较3组飞行员视力情况、视觉质量和生活质量结果. 结果 屈光正常组99例(198眼),SE(0.00士0.50)D;屈光不正组90例(180眼),SE(-2.06士1.75)D;屈光术后组108例(216眼),SE(0.00±0.74)D,±0.50 D范围内占68.1％,土1.00 D范围内占90.3％.屈光术后组飞行员裸眼视力≥1.0的眼有185只(85.6％),≥0.5的眼有213只(98.6％).3组飞行员仅BUT、空间频率为12时的眩光对比敏感度、角膜散光、角膜表面非对称性指数(surface asymmetry index,SAI)差异有统计学意义(H=6.910～26.075,P＜0.05);屈光正常组与屈光术后组的BUT、SAI差异有统计学意义(H=2.465、4.449,P＜0.017),其他视觉质量指标差异均无统计学意义(P＞0.017).屈光术后飞行员在症状、社会活动、精神心理3个模块的评分与屈光正常飞行员差异均无统计学意义(P＞0.017). 结论 屈光术后飞行员的远期视觉质量和视功能比较稳定,可以达到屈光正常飞行员的标准.“,”Objective To evaluate the visual quality and functions of the civil pilots after corneal refractive surgery (CRS) and to explore the safety and long-term stability of CRS.Methods Two hundred and ninety-seven pilots,who were treated in Ophthalmology Department of West China Hospital,Sichuan University,were selected as subjects in this study.Their visual acuity,refraction,corneal topography,contrast sensitivity and break-up time (BUT) were detected and the subjective questionnaires were surveyed.The pilots were divided by spherical equivalent (SE) into emmetropia group:the SE of any eye was ≤+0.50 D or ≥-0.50 D,refractive error group:the SE of any eye was-0.75--6.00 D and CRS group:the pilots had the history of CRS.Results ①There were 99 pilots (198 eyes) in emmetropia group [SE (0.00±0.50) D];90 pilots (180 eyes) in refractive error group [SE (-2.06±1.75) D];108 pilots (216 eyes) in CRS group [SE (0.00±0.74) D].The SE of 68.1％ pilots in CRS group was within ±0.50 D,90.3％ pilots was with in ±1.00 D.②The uncorrected visual acuity of 85.6％ pilots (185 eyes) of CRS group was ≥1.0 while 98.6％ pilots (213 eyes) achieved ≥0.5.③There were significant differences on BUT,glare contrast sensitivity function-12,corneal astigmatism,surface asymmetry index (SAI) among 3 groups (H =6.910-26.075,P ＜ 0.05).There were no significant differences in the index of visual quality between emmetropes and CRS group except BUT and SAI (H =2.465,4.449,P＜0.017).There were no significant differences in symptom,social activity,mental and psychology domains between emmetropes and CRS group (P＞0.017).Conclusions The long-term visual quality and functions of the pilots by CRS show stable effects and compatible to the criteria of emmetropic pilots.
