摘要
目的:探讨准分子激光原位角膜磨镶术(laser in situkera-tomileusis,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≥2.00D)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1moORK和LASIK术后裸眼视力较术前均明显提高,ORK术后裸眼视力为0.92±0.18,LASIK术后裸眼视力为0.85±0.18,两术式间相比较差异无统计学意义(t=1.82,P=0.07)。ORK术后球镜度为0.12±0.98,LASIK术后为0.16±1.24(t=1.87,P=0.07),两术式间差异无统计学意义。ORK术后散光度为-0.61±1.12,LASIK术后为-1.10±1.00(t=2.12,P=0.04),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。
AIM： To compare 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 astigmatism. METHODS： 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 to compare the clinical effects on high astigmatism . RESULTS： One month after surgury, UCVA was 0.92±0.18 of ORK and 0.85±0.18 of LASIK,there was no significant difference of UCVA between ORK and LASIK （t=1.82,P=0.07）.Remnant myopia of ORK was 0.12±0.98,and 0.16±1.24 of LASIK, there was no significant difference of remnant myopia between ORK and LASIK （t=1.87,P=0.07）. Remnant astigmatism of ORK was -0.61±1.12,and -1.10±1.00 of LASIK, there was significant difference of remnant astigmatism between ORK and LASIK（t=2.12,P=0.04）. CONCLUSION： For high astigmatism,ORK is more effective and more predictive than LASIK.
