Objective To study the clinical effect of the combination of cataract ultrasonic emulsification and multifocal aspherical intraocular lens in cataract patients through evaluating different intraocular lenses elimi-nating spherical aberration. Methods 180 patients(180 eyes)with senile cataract were included between,2001 and 2005.The patients were divided into three group (n = 60 each),based on the admition time. Implantion of ReSTOR-SN60D3 is multifocal aspherical intraocular lens(SN60D3),implantion of SN60AT lens is single spheri-cal intraocular lens (SN60AT),and implantion of SN60WF lens is single aspherical intraocular lens (SN60WF group). Three months after operation,the refractive state,focus depth,modulation transfer function(MTF),and higher-order aberrations were measured ,and the visual quality were investigated. Results There was no signifi-cant difference in vision in three groups before operation(P > 0.05). After operation,the UCNVA of SN60D3 group was significantly better than the SN60AT group and SN60WF group(P < 0.05). Under 3 mm pupil diame-ter,spherical aberration of SN60D3 group and SN60WF Z(4,0)were less than SN60AT group(P < 0.05), SN60D3 group and SN60WF only under 5 CPD spatial frequency MTF(HOA)value was superior to the SN60AT group(P<0.05);The score of near vision,reliance on vision correction and limitation of operation of patients in SN60D3 group were higher than other two groups(P<0.05). Visual clarity and day vision fluctuations of patients in SN60D3 group is better than single focal sphere group(P<0.05). Conclusion In multifocal aspherical intra-ocular lens,general spherical aberrations and higher-order aberrations is smaller,effect of naked near vision is bet-ter and the rest of the vision is stable ,which can bring good visual quality for cataract patients after operation.
