Objective To evaluate monochromatic aberrations （MA） with intraocular lenses （IOLs） using a model eye and Hartmann-Shack aberrometry for measurement． Methods This was a prospective study. Part I： There were 5 different IOL refractive powers （Alcon， SA60AT， +10 D， +15 D， +20 D， +25 D and +30 D）． Part II： There were three different +20 D IOLs （SA60AT； Akreos Adapt， Bausch & Lomb； AR40e， AMO）． IOLs were tested in a fluid-filled model constructed to replicate the optical conditions of a pseudophakic human eye at different wavelengths of 436， 486， 525， 546， 589， 660 and 710 nm． Those images were caught by CCD and analyzed in MATLAB． A single-factor analysis of variance and Pearson correlation analysis were used for statistical evaluation. Results Part I： Positive correlations were found between IOL refractive power and aberrations for spherical aberrations （SA， Z12， r=0.599， P<0.05）， vertical coma （VC， Z7， r=0.817， P<0.05） and horizontal coma （HC， Z8， r=0.488， P<0.05）． There was no correlation between IOL refractive power and root mean square of total higher-order aberration （RMSh， r=0.007， P>0.05）． No correlation was found between wavelength and aberrations for SA （r=-0.213， P>0.05）， VC （r=-0.074， P>0.05）， HC （r=0.021， P>0.05） and RMSh （r=-0.322， P>0.05）． Part II： There was a significant difference among the 3 IOLs in aberrations， SA （F=74.637， P<0.05）， HC （F=6.719， P<0.05） and RMSh （F=11.768， P<0.05）． There was no difference in VC （F=1.295， P>0.05）． AR40e had the least SA， HC and RMSh of the three IOLs． There was no correlation between wavelength and aberrations for SA （r=0.007， P>0.05）， VC （r=-0.312， P>0.05）， HC （r=-0.238， P>0.05） and RMSh （r=0.246， P>0.05）． Conclusion The MA of IOLs can be evaluated in this model eye. This is useful for an improvement in the optical quality of IOLs and also could be a better choice for patients．
