<b>AIM:</b> To compare higher order aberrations in two aspherical intraocular lenses (IOLs):Akreos advanced optics (AO) and Dr. Schmidt Microcrystalline 6125 aspheric anterior surface (MC6125AS) with each other.<b>METHODS:</b> Forty eyes of 39 patients underwent phacoemulsification and Akreos AO and MC6125AS were implanted in their eyes in a random manner. Three months post-operatively, higher order aberrations including spherical aberration, coma aberration, and total aberrations were measured and compared.<b>RESULTS:</b> The total aberration was 0.24±0.17 in eyes with Dr. Schmidt and 0.20±0.01 in eyes with Akreos AO (<i>P</i>=0.361). The mean of coma aberration was 0.17±0.21 and 0.09±0.86 in Dr. Schmidt and Akreos lenses, respectively (<i>P</i>=0.825). Total spherical aberration was almost the same in both groups (Mean:0.05, <i>P</i>=0.933). Best corrected visual acuity in Akreos AO (0.10±0.68) and Dr. Schmidt (0.09±0.67) did not differ significantly (<i>P</i>=0.700).<b>CONCLUSION:</b> There is no statistically significant difference in the higher order aberrations between these two aspherical lenses.
