title: Visual Outcome and Patient Satisfaction of Low-Power-Added Multifocal Intraocular Lens.
abstract: OBJECTIVE
  To evaluate visual outcome and patient satisfaction following implantation of multifocal intraocular lenses (IOLs) with a +1.5 diopters (D) addition compared with monofocal IOLs.
  
  
  METHODS
  This prospective, nonrandomized, comparative case series involved 48 eyes (24 patients) who underwent cataract surgery with implantation of low-power-added multifocal IOLs (LS313-MF15; multifocal group) and 48 eyes (24 patients) with conventional monofocal IOLs (CTS204; monofocal group). Visual acuity (VA), defocus curves, refraction, contrast sensitivity, glare, ocular optical quality, and scores in questionnaire were assessed 6 months postoperatively.
  
  
  RESULTS
  Uncorrected VA at intermediate and near distance tended to be better in the multifocal group, with significant differences at 50 cm (P=0.03). The defocus curve showed significantly different VA at vergences of -1.5 and -2.0 D (P=0.02 and P=0.03, respectively). Results of postoperative refraction, contrast sensitivity, glare, and optical quality were similar (P>0.05), although coma-like aberration was higher in the multifocal group (P=0.04). Despite of similar levels of visual disturbances (P>0.05), disturbances in activities and spectacle use at intermediate working distance were significantly less frequent in the multifocal group (P=0.03 and P=0.04, respectively). Multifocal group showed significantly greater overall satisfaction (P=0.02).
  
  
  CONCLUSIONS
  Low-power-added multifocal IOLs yielded better intermediate and near vision without increasing optical phenomena compared with monofocal IOLs.
