目的：调查分析海军某部入伍新兵行角膜屈光手术后的视觉相关生活质量。

方法：在2014/2016年海军某部入伍新兵查体眼科复检过程中，采用问卷调查入伍新兵的一般资料及视觉相关生活质量(NEI-VFQ-25量表)，并详细记录每位受检者视力、电脑验光、对比敏感度等眼科检查结果。

结果：本研究纳入入伍新兵2 760人，其中接受过近视角膜屈光手术者340例(12.32%)，手术方式包括角膜基质切削术(89.71%)和角膜表层切削术(10.29%)。根据术前等效球镜度将已行近视角膜屈光手术的受检者分为低度近视组(≤-3.00D，134例)、中度近视组(>-3.00D～<-6.00D，159例)和高度近视组(≥-6.00D，47例)，三组受检者术后屈光度在±1.0D范围内者分别为128例(95.52%)、153例(96.23%)、38例(80.85%)，低、中度近视组明显高于高度近视组(均P<0.0167)。三组受检者自然光线和眩光条件下各空间频率对比敏感度均有差异(P<0.05)，低、中度近视组均高于高度近视组(P<0.05)。三组受检者术后视觉相关生活质量评分具有差异(P<0.05)，低度近视组(6.25±8.61分)、中度近视组(6.87±8.51分)显著低于高度近视组(9.84±9.76分)(均P<0.05)。

结论：新兵角膜屈光手术后视觉相关生活质量与术前屈光度数有关，术前屈光度低的新兵术后视觉相关生活质量好于术前屈光度高的近视新兵。

METHODS:New recruits in a navy unit during 2014-2016 were interviewed druing recheck ophthalmic examination through a questionnaire, including basic data and the Visual Function Questionnaire-25(VFQ), and also checking the visual acuity, contrast sensitivity(CS), optometry.

RESULTS: Among 2 760 new recruits, 340 persons(12.32%)had undergone corneal refractive surgeries, which included corneal stroma surgery(89.71%)and corneal surface surgery(10.29%). According to the preoperative myopia spherical equivalent, the subjects were divided into three groups: mild myopia group(≤-3.00D, 134 cases), moderate myopia group(>-3.00 D to < -6.00D, 159 cases), and high myopia group(≥-6.00D, 47 cases). The postoperation spherical equivalent range ±1.0D is 128 cases(95.52%), 153 cases(96.23%), 38 cases(80.85%)in mild myopia group, moderate myopia group and high myopia group respectively. The contrast sensitivity(CS)were statistically significant among three different diopter groups under natural light and glare conditions(P<0.05), the CS of the low myopia group and moderate myopia group were higher than in high myopia group(P<0.05). The visual-related quality of life scores were statistically significant among three group(P<0.05). The scores of low(6.25±8.61)points and moderate myopia groups(6.87±8.51)points were significantly better than that of high myopia group(9.84±9.76)points(P<0.05).

CONCLUSION:The vision-related quality of life in new recruits after corneal refractive surgery in the unit is related with preoperative diopter of refractive error. The vision-related quality of life in recruit with lower diopter are better than in recruit with higher dioper.
