方法：回顾性分析2010-01/2013-12来我院进行波前像差引导的LASIK手术患者762例1 524眼。所有患者术中均顺利完成虹膜识别并记录眼球旋转的角度。将眼球旋转角度与患者年龄、性别、眼别、屈光度以及是否主视眼进行统计学分析。其中对眼球旋转角度与年龄和屈光度的关系分别进行相关分析，而与性别、眼别和是否主视眼的关系则分别进行t检验。

结果：患者眼球旋转角度为0～9.7度，平均3.08±2.22度。其中男性444例888眼，平均旋转3.05±2.26度，女性318例636眼，平均旋转3.12±2.15度，两者之间比较差异无显著性(t=1.905，P=0.168)； 患者平均年龄22.6±5.4a，年龄与眼球旋转程度之间无明显相关性(r=-0.012，P=0.748)； 平均球镜度数为-4.76±1.77度， 与眼球旋转程度无明显相关性(r=0.017，P=0.633)； 平均柱镜度数为-0.60±0.64度，与眼球旋转无明显相关性(r=-0.004，P=0.910)。所有患者主视眼旋转3.0±2.17，非主视眼为3.11±2.12，两者之间差异无显著性(t=-0.521，P=0.603)。

结论：准分子手术中发生眼球旋转的程度与年龄、性别、眼别、屈光度数及是否主视眼均无明显相关性。

METHODS: A total of 762 wavefront-guided LASIK patients with 1524 eyes were retrospectively analyzed from January 2010 to December 2013 in our hospital. Iris recognition was accomplished successfully and eye cyclotorsion degrees were recorded intraoperatively for all the patients. The correlations between eye cyclotorsion degrees and patient's age, gender, different eye, diopter and the dominant eye or not were statistically analyzed. In which correlation analysis was used to analyze the relationship between eye cyclotorsion degrees and age and diopter, while the correlations with gender, different eye and the dominant eye or not were analyzed using t-test.

RESULTS: The eye cyclotorsion degrees of patients were 0 to 9.7 degrees with an average of 3.08±2.22 degrees. Amongst the average cyclotorsion of 444 men with 888 eyes were 3.05±2.26 degrees, 318 women with 636 eyes were 3.12±2.15 degrees and there were no significant differences(t=1.905, P=0.168). The average age of all the patients was 22.6±5.4y. No significant correlation was found between cyclotorsion degrees and age(r=-0.012, P=0.748). The mean spherical equivalent was -4.76±1.77 degrees, and there was no significant correlation between the eye cyclotorsion degrees and spherical equivalent(r=0.017, P=0.633). The mean cylinder was -0.60±0.64 degrees of no significant correlation with eye cyclotorsion degrees(r=-0.004, P=0.910). The cyclotorsion of dominant eyes of all the patients was 3.0±2.17 degrees, and the non-dominant eyes were 3.11±2.12 degrees. No significant differences were found(t=-0.521,P=0.603).

CONCLUSION: The eye cyclotorsion degrees occurred in LASIK surgery had no correlation with age, gender, different eye, diopter and the dominant eye or not.
