摘要 目的观察当散光主要来源于角膜前表面或眼内时,波前像差优化准分子激光角膜原位磨镶术(LASIK)对近视散光的治疗效果,评价眼内散光(ocular residual astigmatism,ORA)对波前像差优化LASIK临床疗效的影响。方法收集拟行LASIK手术的近视散光患者65例(65眼),根据术前眼内散光与全眼散光的比值将患眼分为2组,比值<1为低ORA组,比值≥1为高ORA组,所有患者均行波前像差优化的LASIK手术。术后6个月观察2组视力、屈光度、成功指数及全眼高阶像差的差异。结果术后6个月,低ORA组角膜平面的柱镜值为与高ORA组,差异有统计学意义(P=0.028)。低ORA组及高ORA组的成功指数比较,差异有统计学意义(P=0.016)。低ORA组术后慧差的增加值小于高ORA组(P=0.023),2组术后总高阶像差及球差的增加值差异无统计学意义(P>0.05)。结论当散光主要来源于眼内时,波前像差优化LASIK对散光的矫正效果较差;对高ORA患者,手术的设计可综合考虑角膜及全眼散光,或采用晶体手术。
