title: Correction of presbyopia with refractive multifocal phakic intraocular lenses.
abstract: OBJECTIVE
  To evaluate the efficacy of and specify the conditions required for implantation of an anterior chamber multifocal phakic intraocular lens (IOL) to correct presbyopia.
  
  
  METHODS
  Monticelli Clinic, Marseilles, France.
  
  
  METHODS
  Fifty-five eyes of 33 patients (21 women, 12 men) had implantation of a foldable anterior chamber multifocal phakic IOL. The initial refraction was between -5.00 diopters (D) and +5.00 D. The IOL had an addition of +2.50 D. An uncorrected distance acuity of 0.6 or better (decimal scale) and an uncorrected near acuity (Parinaud scale) of 3 or better (Parinaud 2 approximately equal to Jaeger 1) was considered a successful postoperative result.
  
  
  RESULTS
  The mean follow-up was 42.6 weeks +/- 18 (SD). Postoperatively, the mean refraction was -0.12 +/- 0.51 D, the mean decimal uncorrected distance acuity was 0.78 +/- 0.20, and the mean Parinaud uncorrected near acuity was 2.3 +/- 0.6. Eighty-four percent of eyes achieved an uncorrected distance acuity of 0.60 or better and an uncorrected near acuity of Parinaud 3 or better. The IOL was explanted in 4 eyes for different, but essentially optical, reasons. No significant anatomic complications were observed.
  
  
  CONCLUSIONS
  Implantation of an anterior chamber multifocal phakic IOL to correct presbyopia was effective and gave good predictability. The procedure is reversible in cases of patient intolerance to the IOL, unwanted optical phenomena, or complications. Strict inclusion criteria should be used for patient selection.
