目的调查某部现役军人角膜屈光手术后视觉质量的情况.方法选择在成都军区总医院眼科体检的现役军人为对象,于201 1年7月2～15日在成都军区总医院眼科中心检查,根据术前屈光度分为低度近视组94只眼,中度近视组345只眼,高度近视组69只眼;抽取100名裸眼视力(UC-VA)≥1.0的军人进行对比敏感度检查,作为正常对照.检查裸眼视力、矫正视力、屈光度和对比敏感度,并进行比较分析.结果被检查的3 107人中,有8.50％ (264/3 107)曾接受不同类型的激光角膜屈光手术.术前高度近视组(≥-6.00D),UCVA≥1.0的占62.32％ (43/69),屈光度在±1.0 D之内的86.96％ (60/69),均显著低于术前低度近视组的91.49％ (86/94)和96.81％ (91/94),(P＜0.05)以及中度近视组的83.77％ (289/345)和94.78％ (327/345) (P ＜0.05);术前高度近视组各频率对比敏感度值都显著低于正常对照组(P＜0.05),也显著低于术前低度和中度近视组(P＜0.05).结论术前屈光度越高,术后视力的稳定性较差,对比敏感度各频率明显降低,对视觉质量要求高的兵种应做严格限制.

Objective To investigate the visual function of active-duty military personnel of the People's Liberation Army (PLA) Ground Force after laser corneal refractive surgery (LCRS).Methods Active-duty military personnel from one regiment of the PLA Ground Force were selected as subjects for this study.This study was undertaken at the Eye Centre of the Chengdu Military General Hospital during July 2 to 15,2011.According to preoperative refraction,the subjects who had received LCRS were divided into mild,moderate and severe myopia groups.Results Of the 3,107 participants tested,8.50％ (264/3107) had received previous LCRS.In the preoperative severe myopia group (≥-6.00 D),62.32％ (43/69) of the subjects had UCVA ≥ 1.0 and 86.96％ (60/69) had refraction values within ± 1.0 D; these values were both significantly lower than those in the preoperative mild myopia group 91.49％ (86/94) and 96.81％ (91/94),respectively (P ＜0.05) and in the moderate myopia group 83.77％ (289/345) and 94.78％ (327/345),respectively (P ＜0.05).The subjects in the preoperative severe myopia group had significantly lower contrast sensitivity at all frequencies relative to those in the control group (P ＜0.05) as well as those in the mild and moderate myopia groups (P ＜0.05).Conclusions The individuals with higher preoperative refraction have relatively less stable postoperative visual acuity and significantly decreased contrast sensitivity at any frequency,making them unable to meet the strict visual requirements in a variety of environments among the various branches of the armed forces.
