Purpose: To compare high–order aberrations (HOA) in patients who had cataract surgery and implantation of 2 types of acrylic intraocular lens ( hydrophobic MA 60 AC or hydrophilic XLSTABI). Methods: Forty eyes were included in this study. Eyes of group I ( n = 20 ) received an acrylic hydrophobic ( MA 60 AC) and eyes of group II (n = 20 ) received an acrylic hydrophilic ( XLSTABI) intraocular lens. Optical aberrations were measured with NIDEK OPD–SCAN at least one month after cataract surgery for a 6 mm pupil diameter using a sixth order Zernike polynomials decomposition. Results: In a group I, the root mean square (RMS) coefficient for the total higher aberration was 2.059 µm. The RMS of the tilt, coma, trefoil, tetrafoil, spherical aberration and secondary astigmatism were 0.848, 0.368, 0.524, 0.077, 0.319 et 0.153 µm, respectively. In a group II, the RMS coefficient for the total higher aberration was 2.464 µm. The RMS of the tilt, coma, trefoil, tetrafoil, spherical aberration and secondary astigmatism were 0.520, 0.220, 0.520, 0.017, 0.290 et 0.136 µm, respectively. There was statistical difference in HOA between the two groups for the tilt and the coma aberration (P<0.05). There was more aberrations in MA60AC. Conclusions: There was statistical difference between the two groups regarding the magnitude of HOA.
