1、非球面人工晶体植入术后全眼球差的可预测性分析赵晓彬贾志旸董素婷（河北省人民医院眼科石家庄050051）【摘要】目的观察超声乳化白内障吸除术后植入不同球差的非球面IOL，术后假晶体眼全眼球差的可预测性，探讨在临床上个性化植入非球面IOL的可行性。方法前瞻性病例系列研究。收集在我院就诊拟行手术治疗的年龄相关性白内障患者58例（58眼），将患者随机分为3组，行超声乳化白内障吸除并分别植入以下几种非球面IOL中的一种：TecnisZ9003，球差为-0.27um；ArcySofIQ，球差为-0.20um；PY-60AD，球差为-0.18um。术后3个月观察患者的裸眼视力、最佳矫

2、正视力、等效球镜值、6.0mm瞳孔直径时的角膜及全眼球差。采用t检验和方差分析对获得的数据进行统计学分析。结果所有患者术后全眼球差预测值为0.051±0.082um，测量值为0.037±0.074um，预测值与测量值之间差异无统计学意义（P=0.206)。平均预测误差为0.015±0.057um，3组之间差异无统计学意义（P=0.978）。所有患者术前术后角膜球差相比，差异无统计学意义。结论超声乳化白内障吸除术后植入不同球差的非球面IOL，术后假晶体眼全眼球差的可预测性较好，为非球面IOL的个性化植入提供了理论依据。【关键词】超声乳化白内障吸除术；白内障；晶体，人工；球
