Objective To investigate the wavefront aberration and contrast sensitivity after implantation of Tecnis MF and Array intraocular lens(IOL)in patients’eyes with cataract.

Method: IOL implantations were performed in 96(108 eyes)cataract patients.Among which 40 patients(52 eyes)randomly selected ZM900 group，and 56 patients(56 eyes)selected as SA40N group.Aberration and contrast sensitivity were examined at 1 month and 3 month postoperatively，with Allegretto Wave Analyzer and ZM-800 Contrast Sensitivity.

Results:The SA40N group showed significantly higher spherical aberration(p<0.05)，C7/C8 aberration(p<0.05)and RMSh(p<0.05)than the ZM900 group at 1 month and 3 month postoperatively.Compare to SA40N，ZM900 group better in contrast sensitivity after 1 month and better in 1.8c/d、3c/d only after 3 month(p<0.05).

Conclusion:ZM900 intraocular lens manifested preferably better capability to decline aberration and raise contrast sensitivity.Therefore，the ZM900 is becoming the tendency of future in choice of intraocular lens.
