目的 对驻京某部准分子激光角膜屈光手术后的新兵进行干眼症调查。方法 在2012年度新兵入伍体检时，选择283例准分子激光角膜屈光手术的新兵（手术组）并随机抽取其他273例新兵（非手术组）纳入研究，首先排除结角膜炎等其他疾患，然后两组分别进行问卷调查及干眼症的特异性检查，之后进行统计分析。结果 有干眼症状的（包括：干涩、异物感、疲劳感、不适感等），手术组：79例，占28%，非手术组：17例，占6%；诊断为干眼症的，手术组：53例，占18.72%，非手术组：12例，占6.23%。两组患病率差异有统计学意义（χ²=27.65,P＜0.01）。结论 准分子激光角膜屈光手术后的新兵干眼症的发病率明显高于非手术者。

Objective To investigate the dry-eye disease in recruits who have received excimer laser keratomileusis. Methods During the physical examination of recruits for 2012, 283 recruits who had undergone excimer laser keratomileusis were randomly selected (surgery group) while other 273 non-surgery recruits (non-surgical group) served as control. After keratoconjunctivitis and other disorders were excluded, a survey and a dry eye specificity examination were conducted in the two groups for statistical analysis. Result Seventy-nine recruits (28%) suffered from dry eyes（including dry eyes、foreign body sensation、feeling of fatigue and discomfort）in surgical group while in non-surgical group there were only seventeen cases (6%). Fifty-three cases (18.72%) were diagnosed with dry eyes in surgical group compared to twelve cases (6.23%) in the other group. The difference was statistically significant. Conclusion Dry eyes are much more prevalent among recruits who underwent excimer laser keratomileusis.
