title: Ocular aberrations after cataract surgery with hydrophobic and hydrophilic acrylic intraocular lenses: comparative study.
abstract: OBJECTIVE
  To compare tilt and some higher-order aberrations (HOAs) in patients who had cataract surgery and implantation of 2 types of acrylic intraocular lens (IOL), the hydrophobic MA60AC (Alcon) or the hydrophilic XLSTABI (Ioltech).
  
  
  METHODS
  Fondation Ophtalmologique Adolphe de Rothschild, Department of Pr Hoang-Xuan, Paris, France.
  
  
  METHODS
  Sixty eyes were included in this study. Eyes in group 1 (n = 30) received the acrylic hydrophobic MA60AC IOL, and eyes in group 2 (n = 30) received the acrylic hydrophilic XLSTABI IOL. Optical aberrations were measured with Nidek OPD-Scan at least 1 month after cataract surgery for a 6.0 mm pupil diameter using a 6th-order Zernike polynomials decomposition.
  
  
  RESULTS
  In group 1, the mean root-mean-square (RMS) coefficient for the total higher aberration was 0.86 microm +/- 0.38 (SD). The mean RMS of the tilt, coma, trefoil, tetrafoil, spherical aberration, and secondary astigmatism was 0.81 +/- 0.45 microm, 0.38 +/- 0.30 microm, 0.55 +/- 0.18 microm, 0.13 +/- 0.23 microm, 0.30 +/- 0.13 microm, and 0.17 +/- 0.21 microm, respectively. In group 2, the mean RMS coefficient for the total higher aberration was 0.72 +/- 0.31 microm. The mean RMS of the tilt, coma, trefoil, tetrafoil, spherical aberration, and secondary astigmatism was 0.55 +/- 0.30 microm, 0.24 +/- 0.19 microm, 0.50 +/- 0.23 microm, 0.07 +/- 0.22 microm, 0.32 +/- 0.13 microm, and 0.14 +/- 0.14 microm, respectively. There was a statistical difference in aberrations between the 2 groups for the tilt and the coma aberrations (P<.05). There were more aberrations in the MA60AC IOL group.
  
  
  CONCLUSIONS
  The design of the IOL influenced ocular aberrations after cataract surgery. There were more tilt and coma aberrations in the MA60AC IOL group.
