单焦点及多焦点非球面IOL植入术后的高阶像差对比

摘要

AIM:To compare the higher-order aberrations between implantations of AcrySof and AcrySof ReStor multifocal aspherical intraocular lens(IOL) with various pupil diameters.METHODS:Fifty-four patients(62 eyes)with bilateral senile cataracts were retrospectively selected.Patients were operated with phacoemulsification and IOL implantation.They were divided into two groups based on the IOL implantation of AcrySof IQ and AcrySof ReStor.Wave front aberration:spherical aberration(C12)and the root mean square of the total higher-order aberration(RMSh)were observed 3 months after surgery.RESULTS:The larger the pupil was, the higher the C12 and RMSh were in the eyes (P<0.01).There were no statistical differences in C12 or RMSh between two groups at 5, 6 or 7mm pupil diameters (P>0.05). CONCLUSION:There are no differences between AcrySof IQ group and AcrySof ReStor group at 5, 6 or 7mm pupil diameters.%目的:比较不同瞳孔直径下单焦点AcrySof IQ(SN60WF)及多焦点非球面人工晶状体AcrySof ReStor+3(SN6AD1)植入术后的高阶像差.方法:回顾性选取2009-08/2010-04在我院眼科行超声乳化吸出术联合人工晶状体植入术的患者54例62眼,按照植入人工晶状体的不同类型分为两组:AcrySof IQ组及AcrySof ReStor组.主要观察项目为术后球差(C12)及总高阶像差的均方根(RMSh).结果:两组术后3mo应用波前像差仪(Allegro Analyzer)检查,瞳孔直径在5,6,7mm时,A组球差和B组球差和RMSh均方根均随着瞳孔直径增大而增加,差异有统计学意义(P<0.01);瞳孔直径为5,6,7mm时,A组总高阶像差与B组相比,差异均无统计学意义(P>0.05).结论:在瞳孔直径5,6,7mm的时候AcrySof IQ及AcrySof ReStor的高阶像差基本无差别.
