目的：目的：评价上级或鼻铰链位置对激光原位角膜磨镶术（LASIK）后角膜感觉和干眼的影响。设置：马吉尔视力矫正研究中心，风暴眼研究所，南卡罗来纳州，查尔斯顿，南卡罗来纳州，美国。方法：这项前瞻性随机盲法研究包括47例双侧近视LASIK手术患者。第一只眼被随机分配到鼻或上级铰链瓣;对侧眼有替代位置。在术前和术后1周、1个月、3个月和6个月评价视力、对比敏感度、角膜感觉、基础分泌物测试、泪膜破裂时间、结膜和角膜染色以及主观问卷。结果：两组干眼症发生率相同，干眼症发生率与对照组比较差异有统计学意义（P <0.05）。但鼻铰链型眼的鼻感觉明显好于上级铰链型眼（P
Purpose: To evaluate the effects of a superior or nasal hinge location on corneal sensation and dry eye after laser in situ keratomileusis (LASIK).Setting: Magill Research Center for Vision Correction, Storm Eye Institute, Medical University of South Carolina, Charleston, South Carolina, USA.Methods: This prospective randomized masked study included 47 patients having bilateral myopic LASIK surgery. The first eye was randomly assigned to have a nasal or superior hinge flap; the fellow eye had the alternate location. Visual acuity, contrast sensitivity, corneal sensation, basic secretion test, tear film breakup time, conjunctival and corneal staining, and a subjective questionnaire were evaluated preoperatively and postoperatively at 1 week and 1, 3, and 6 months. The Wilcoxon signed rank test and paired t test were used for comparison.Results: Dry eye occurred with the same frequency in both groups. However, eyes with the nasal hinge had significantly better nasal sensation than those with the superior hinge (P
