目的探讨角膜波面像差引导的准分子激光个体化屈光手术(ORK)程序指导下的准分子激光原位角膜磨镶术(LASIK)矫正近视合并中高度散光的效果分析.方法回顾性病例研究.应用德国爱丽丝八代准分子激光治疗仪ORK治疗系统对34例(48眼)近视合并中高度散光(≥2.0 D)患者进行LASIK治疗.观察6个月,比较手术前后视力、屈光度、散光及散光轴向的变化.数据采用配对t检验进行分析.结果术后6个月裸眼视力(UCVA)≥0.8者48眼(100％),UCVA≥1.0者47眼(98％),UCVA≥术前最佳矫正视力(BCVA)47眼(98％),术后UCVA与术前BCVA差异无显著统计学意义(t=-0.538,P＞0.05).术后残留散光度在1.00 D以内40眼(83％),在0.50 D以内15眼(31％),平均值为(0.69±0.40)D,散光轴位偏斜度均≤5..结论 ORK程序指导下的LASIK手术治疗近视合并中高度散光安全、有效.

Objective To investigate the clinical efficacy of ORK (optimized refractive keratectomy customized ablation manager) for myopia combined with medium and high astigmatism.Methods It was retrospective study.Thirty-four myopia patients forty-eight eyes combined with medium and high astigmatism (≥2.0 D) were treated with ORK by excimer laster treatment system of Esiris of Germany.Preoperative and postoperative tests included vision,dioptre,astigmatism and the axis of astigmatism.Data were analyzed using paired t test.Results After 6 months' follow up,the results showed that uncorrected visual acurity (UVAC) was over 0.8 in 100％ and 1.0 in 98％ repectively.The postoperative UCVA better than preoperative best-corrected visual acuity (BCVA) was in 98％.There was no significant difference between UVAC and BCVA (t=-0.538,P＞0.05).There were 40 eyes (83％) within 1.00 D of astigmatism.15 eyes (31％) were within 0.5 D of astigmatism.The average residual astigmatism was 0.69±0.40 D.Astigmatic axial change within 5°.Conclusion It proved that the ORK is an effective and safety method to treat myopia combined with medium and high astigmatism.
