目的 探讨人工虹膜识别定位技术在准分子激光原位角膜磨镶术(LASIK)中的应用价值.方法 2008年3月至2010年1月在我院行LASIK术治疗的复合性近视散光患者314例(410眼),分为两组:Ⅰ组162例(205眼),年龄为18～35岁,散光度为-1.0～-3.0 D,球镜屈光度为-1.25～-4.75 D,LASIK术中采用人工虹膜识别定位技术;Ⅱ组152例(205眼),年龄为18～40岁,散光度为-1.0～-2.5 D,球镜屈光度为-1.00～-5.50 D,同期行常规LASIK手术.人工虹膜识别定位方法:术前应用数码照相裂隙灯,照取水平细裂隙光带投照在虹膜瞳孔中央的清晰虹膜像,术中以该图像为依据来确定、标记术眼水平轴,激光治疗中始终保持该轴在视野中央并与手术显微镜中水平基准轴平行.术前、术后6个月,分别在电脑验光基础上应用综合验光方法测定散光度和轴向.采用SPSS 17.0统计软件,对两组术后残余散光度及轴向进行配对t检验.结果 两组手术均顺利完成,无LASIK相关并发症发生;术后恢复顺利,术后6个月内裸眼视力与预期相符,无明显不适主诉.Ⅰ组术后散光度为(-0.73±0.34)D,Ⅱ组术后散光度为(-0.68±0.53)D,两组差异无统计学意义(t=-1.200,P=0.231);Ⅰ组术后散光轴向为(13.25±13.09).,Ⅱ组为(17.48±17.93).,两组差异有统计学意义(t=-2.755,P=0.006).结论 人工虹膜识别定位技术在LASIK术中矫正散光及调整眼位有较好的应用价值,可在多种屈光手术中推广使用.

Objectivt To study the value of the application of artificial iris recognition for laser in situ keratomileusis (LASIK). Methods A total of 314 patients with myopic astigmatism were recruited for the study. The patients was divided into 2 groups by whether or not artificial iris recognition was taken during the operation. The patients with artificial iris recognition were group Ⅰ,and the others were group Ⅱ. There were 162 patients (205 eyes) in group Ⅰ, astigmatism range -1.0- -3.0(-1.56±0.79)D, 110 males (141 eyes), 52 females (64 eyes), and mean age (22.6±5.2)years. There were 152 patients (205 eyes) in group Ⅱ, astigmatism range -1.0--3.0(-1.48±0.65)D, 101 males (135 eyes), 51 females (70 eyes), mean age (23.4±5.8)years. Astigmatism and axial direction were measured 6 months postoperatively. The differences between the two techniques were compared based on astigmatism and its axis. Results Postoperative astigmatism in group Ⅰwas (-0.73±0.34)D, and in group Ⅱ was (-0.68±0.53)D. There were no significant differences between the two groups (t=-1.200, P=0.231). Postoperative axial direction in group Ⅰ was (13.25±13.09)° and in group Ⅱ was (17.48±17.93)°. There were significant differences between the two groups (t=2.755, P=0.006). Conclusion Artificial iris recognition can help to correct astigmatism and axial direction in LASIK, and it can be applied to refractive surgery in general.
