Abstract： 目的:比较高度散光患者虹膜定位波前引导的LASIK(IR-LASIK)手术与常规LASIK手术的临床效果.方法:≥2.0DC的高度散光患者分别使用VISX S4-IR准分子激光机进行IR-LASIK手术(204例338眼)和常规LASIK手术(180例335眼),对术后裸眼视力和残留散光度数进行比较,IR手术组检查了眼球旋转的角度.结果:IR-LASIK手术组术后2d裸眼视力(≥1.0者89.1%)明显优于常规LASIK手术组(≥1.0者83.6%,P<0.05),术后残留散光度数也明显小于常规LASIK手术组(0.56DC vs1.15DC,P<0.01).IR-LASIK手术组波前像差检查的散光度数和轴位均与显然验光结果有一定的差别,所有患眼手术时均发生了眼球旋转.这可能是IR手术后疗效较好的重要原因.结论:IR-LASIK手术能够明显改善高度散光患者术后裸眼视力,减轻术后的散光残留.
