【摘要】目的:探讨准分子激光原位角膜磨镶术(laser in situ keratomileusis,LASIK)与角膜波面像差引导的准分子激光个体化屈光手术(optimized refractive keratectomy customized ablation manager, ORK)治疗近视性高度散光的临床效果和优点。方法:2005/2009年近视性高度散光(散光度≥)行LASIK和ORK治疗各44眼,观察2种手术方法术后1mo散光度的矫正效果。观察指标包括术后裸眼视力、散光度、眼压、裂隙灯检查及角膜地形图。结果:术后1mo ORK和LASIK术后裸眼视力较术前均明显提高,± ,±,两术式间相比较差异无统计学意义(t=,P=)。±,±(t=,P=),两术式间差异无统计学意义。ORK术后散光度为±,LASIK术后为±(t=,P=),两术式间差异有统计学意义,即ORK的矫正效果更好。结论:ORK手术治疗近视性高度散光效果良好。

Abstract AIM: pare and analyze the therapeutic effects of laser in situ
keratomileusis(LASIK)and optimized refractive keratectomy customized ablation manager(ORK)for the treatment of high : LASIK was performed in 44 eyes of 30 patients with high astigmatism and 44 eyes of 31 patients with high astigmatism received ORK. Uncorrected visual acuity (UCVA),astigmatism,slitlamp examination,intraocular pressure(IOP),corneal topography were observed in these patients in 1month followup pare the clinical effects on high astigmatism . RESULTS: One month after surgury, UCVA was ± of ORK and ± of LASIK,there was no significant difference of UCVA between ORK and LASIK (t=,P=).Remnant
