LASIK术中眼球旋转和瞳孔中心移位的相关因素分析

目的 探讨LASIK手术中发生眼球旋转和瞳孔中心移位的影响因素.设计 回顾性临床病例系列.研究对象近视患者131例262眼.方法 对接受双眼LASIK手术的近视患者,应用CustomVueTM软件测量术中眼球旋转及瞳孔中心移位,并探讨其影响因素;按照年龄、性别、眼别、角膜瓣制作方法、等效球镜、术前瞳孔直径、术中瞳孔直径、瞳孔直径差值等因素进行分组,对不同分组的眼球旋转和瞳孔中心移位的结果进行比较.主要指标 术中眼球旋转度数及瞳孔中心移位距离.结果 LASIK手术中平均眼球旋转度数(3.07°±2.07°)(0°～8.6°).平均瞳孔中心移位为(0.33±0.14)mm(0.04～0.51 mm).旋转度数与术前瞳孔直径、术前术中瞳孔差值、术前等效球镜度数具有相关性(r=0.188,0.156,0.130,P均<0.05).术前瞳孔>7.0 mm组眼球旋转度数为(3.35°±2.17°),明显高于术前瞳孔≤7.0 mm组(2.71°±1.89°,P=0.014).右眼瞳孔中心移位(0.39±0.12)mm,明显高于左眼(0.28±0.13)mm(P=0.000).结论 CustomVueTM系统可以测量LASIK术中发生的眼球旋转和瞳孔中心移位.术前瞳孔直径和手术中瞳孔直径变化值可影响眼球旋转度数.右眼的瞳孔中心移位高于左眼.

Influencing factors for eye cyclotorsion and pupil centroid shift during LASIK

Objective To investigate the influencing factors for eye cyclotorsion and pupil centroid shift during LASIK.Design Non-controlled retrospective case series.Participant 131 patients (262 eyes) with myopia received bilateral LASIK.Methods Eye cy- clotorsion and pupil centroid shift were measured with Custom Vue~(TM) software during operation and compared with age,gender,right or left eye,flap-making method,spherical equivalent (SE),pupil diameter before and during operation.Main Outcome Measures The de- gree ...
