title: Visual Performance After Contralateral Implantation of Multifocal Intraocular Lenses With +3.0 and +4.0 Diopter Additions.
abstract: OBJECTIVE
  To evaluate visual performance after contralateral implantation of AcrySof ReSTOR aspheric intraocular lenses (IOLs) with +3.0 and +4.0 diopter near additions.
  
  
  METHODS
  This was a retrospective case study conducted at Tokyo Dental College Suidobashi Hospital in Tokyo, Japan.
  
  
  METHODS
  Eleven patients who were implanted with the SN6AD1 IOL and the SN6AD3 IOL contralaterally were included in this study. The distance, intermediate (1 m, 50 cm), and near (40 and 30 cm) uncorrected and corrected binocular visual acuity (VA), contrast sensitivity, depth of focus, and patient satisfaction were assessed more than 1 month postoperatively.
  
  
  RESULTS
  Postoperatively, the mean uncorrected (corrected) binocular logarithm of the minimum angle of resolution VA levels were as follows: distance, -0.120 (-0.163); intermediate, 1 m, 0.226 (0.012) and 50 cm, 0.037 (0.006); and near, 40 cm, 0.067 (-0.040) and 30 cm, 0.091 (-0.053). The depth of focus had a smooth curve with double peaks. The mean contrast sensitivity was normal at all spatial frequencies. All patients were spectacle independent and expressed high satisfaction.
  
  
  CONCLUSIONS
  Contralateral implantation of multifocal IOLs with +3.0 and +4.0 D additions takes advantage of the good uncorrected near VA provided by both IOLs and may be an option for patients who require a broader range of good uncorrected near VA.
