title: [Initial results obtained with the multifocal lens MF4].
abstract: BACKGROUND
  Most patients depend on glasses for near vision after a cataract surgery with implantation of a monofocal IOL. Implantation of a multifocal IOL offers these patients the possibility to become independent of glasses. The aim of this study was to gain clinical experience with the multifocal MF4-Lens (IOLtech, France).
  
  
  METHODS
  The MF4-lens was implanted in 80 eyes of 40 patients. Corrected and uncorrected near and far vision acuity were evaluated 3 months postop. Patients' satisfaction, the appearance of disturbing optical phenomena and the dependence on glasses were ascertained by means of an anonymous questionnaire.
  
  
  RESULTS
  No surgical complications occurred in the course of this study. Three months after surgery, 92 % of all patients had an uncorrected visual acuity of 0.5 (20/40) or better. The binocular, uncorrected visual acuity was 0.63 (20/32) or better. The corrected far-vision acuity was 0.5 (20/40) or better. 86 % of all patients had an uncorrected near-vision acuity of 0.8 (20/25) and 45 % an uncorrected near-vision acuity of 1.0 (20/20). 94 % of the patients were satisfied with the results of the surgery. 38 % reported on glare and 45 % noticed halos. 67 % of all patients were totally independent of glasses, 27 % needed glasses frequently and 6 % generally.
  
  
  CONCLUSIONS
  The implantation of the multifocal MF4-lens is an effective procedure in particular for near-vision acuity and patient satisfaction. The majority of patients were less dependent on glasses.
