title: Visual outcomes with a single-optic accommodating intraocular lens and a low-addition-power rotational asymmetric multifocal intraocular lens.
abstract: OBJECTIVE
  To compare the visual outcomes and intraocular optical quality in patients with a low-addition (add) power multifocal refractive intraocular lens (IOL) with rotational asymmetry and a single-optic accommodating IOL.
  
  
  METHODS
  Vissum Instituto Oftalmológico de Alicante, Miguel Hérnandez University, Alicante, Spain.
  
  
  METHODS
  Prospective comparative nonrandomized consecutive case series.
  
  
  METHODS
  Consecutive cataract patients had implantation of a low-add-power refractive multifocal IOL with rotational asymmetry (Lentis-Mplus LS-312 MF15) (multifocal group) or a single-optic accommodating IOL (Crystalens HD) (accommodating group). Distance and near visual acuities were evaluated. Ocular optical quality, intraocular aberrations, defocus curve, and contrast sensitivity were evaluated postoperatively.
  
  
  RESULTS
  Of the 66 eyes (40 patients; age 61 to 81 years), 31 were in the multifocal group and 35 were in the accommodating group. Postoperatively, both groups had a significant improvement in the uncorrected and corrected distance visual acuities and uncorrected (UNVA) and corrected near (CNVA) near visual acuities (P <.01). Distance-corrected near visual acuity was significantly better in the multifocal group postoperatively (P ≤.04). No significant differences in UNVA and CNVA were detected postoperatively (P ≥.09). In the defocus curve, the multifocal group had significantly better visual acuities at several defocus levels. The accommodating group had better contrast sensitivity under photopic conditions at all spatial frequencies (P ≤.04). The multifocal group had significantly higher postoperative intraocular tilt (P <.01).
  
  
  CONCLUSIONS
  Both IOLs restored distance vision. The refractive multifocal IOL provided better near visual rehabilitation.
