title: Clinical outcomes and postoperative intraocular optical quality with a microincision aberration-free aspheric intraocular lens.
abstract: OBJECTIVE
  To evaluate the visual outcomes and optical quality with an aspheric intraocular lens (IOL) with no aberration in microincision cataract surgery.
  
  
  METHODS
  Vissum-Instituto de Oftalmológico de Alicante, Alicante, Spain.
  
  
  METHODS
  This prospective cohort study included eyes that had cataract surgery with implantation of an Akreos Adapt Advanced Optics MI60 IOL. Surgery was performed using the Millennium phacoemulsification platform. The IOL was implanted through a sub-1.8 mm incision using the 1.8 Viscoglide cartridge. Visual and refractive outcomes were analyzed during a 12-month follow-up. In addition, postoperative ocular optical quality was evaluated using the Optical Quality Analysis System. Postoperative intraocular optical aberrations were calculated by subtracting corneal aberrations from total aberrations.
  
  
  RESULTS
  The cohort comprised 25 eyes of 25 patients ranging in age from 52 to 83 years. The mean spherical equivalent was -0.47 diopters +/- 0.62 (SD) 3 months postoperatively (P = .72). The mean corrected distance visual acuity improved from 0.54 +/- 0.23 logMAR preoperatively to 0.08 +/- 0.16 logMAR 3 months postoperatively (P<.01). Optical quality analysis showed a mean spatial frequency at 50% of the modulation transfer function (MTF) of 2.85 +/- 0.55 cycles per degree (cpd) and a mean cutoff MTF frequency of 21.50 +/- 7.02 cpd. Postoperatively, the mean intraocular spherical aberration was 0.16 +/- 0.11 microm and the mean primary coma root mean square, 0.23 +/- 0.15 microm.
  
  
  CONCLUSIONS
  Implantation of the aberration-free aspheric IOL was safe and effective and provided excellent visual and refractive outcomes with good optical performance.
