title: Clinical outcomes and optical performance of four differentmultifocal intraocular lenses.
abstract: OBJECTIVE
  The purpose of the present study was to evaluate clinical outcomes and optical performance of 4 different multifocal intraocular lenses (IOLs).
  
  
  METHODS
  Ninety eyes of 51 patients who received Reviol MFM 611, Reviol MFM 625, Acri.LISA, and ReSTOR SN6AD3 multifocal IOLs after cataract surgery were retrospectively evaluated. The patients were similar in terms of age, sex, cataract hardness and axial length. The mean outcome measures were uncorrected and corrected distance visual acuity (UDVA, CDVA), distance-corrected intermediate and near visual acuity (DCIVA, DCNVA), intra or postoperative complications, and contrast sensitivity (CS) results under mesopic conditions. The mean follow up period was 10.5 months (range: 6-12 months).
  
  
  RESULTS
  All cases were within ± 0.75 D of emmetropia. Postoperative increase in UDVA and DCNVA was statistically significant in all groups. The Acri.LISA group showed slightly lower DCIVA compared with the other IOLs. CS was clinically similar between the groups. None of the patients developed any early or late postoperative complication or neuroadaptation problem, which necessitated explantation of the lens.
  
  
  CONCLUSIONS
  All four multifocal lens designs provided satisfactory visual functions and CS results in patients who fulfilled the criteria for multifocal lens implantation.
