Abstract： 目的:观察高度近视合并白内障植入非球面与球面人工晶状体术后视觉质量.方法:回顾性分析高度近视合并白内障患者42眼,其中植入非球面IOL(Alcon SN60WF)22眼,植入球面IOL(Alcon SN60AT)20眼,所有病例术后裸眼视力均>0.2,术后6mo对视力、表观调节力、对比敏感度等视功能检查.结果:术后6mo非球面IOL和球面IOL两组的矫正远视力、矫正远视力后的近视力、表观调节力比较差异均无统计学意义(P>0.05),在暗视及暗视眩光状态下,低、中空间频率非球面IOL组CS和GCS优于球面IOL组,差异有统计学意义(P<0.05),在高频区、明视及明视眩光状态下两组间CS和GCS差异无统计学意义(P>0.05).结论:高度近视合并白内障患者非球面IOL植入术后CS和GCS优于球面IOL植入术后,可以改善视觉质量.
