title: Visual function after bilateral implantation of apodized diffractive aspheric multifocal intraocular lenses with a +3.0 D addition.
abstract: OBJECTIVE
  To evaluate visual function after bilateral implantation of apodized diffractive aspheric multifocal intraocular lenses (IOLs) with a +3.0 diopter addition (add) power.
  
  
  METHODS
  Multicenter study at 5 European sites.
  
  
  METHODS
  Five surgeons prospectively enrolled patients to receive bilateral implantation of AcrySof IQ ReSTOR SN6AD1 IOLs. Assessments included defocus testing, uncorrected and corrected distance visual acuities at various distances, and patient questionnaires.
  
  
  RESULTS
  Ninety-three patients were enrolled. The mean distance-corrected visual acuities at far, intermediate, and near distances were significantly better postoperatively. At 6 months, uncorrected visual acuity (logMAR) was -0.03 +/- 0.13 (SD) at 4 m, 0.20 +/- 0.14 at 70 cm, 0.13 +/- 0.15 at 60 cm, 0.05 +/- 0.18 at 50 cm, and 0.04 +/- 0.11 at 40 cm. The mean patient-preferred near distance was 41 +/- 4 cm, at which distance the mean visual acuity was -0.01 +/- 0.11 logMAR. The defocus curve had a plateau of optimum near vision from 40 to 50 cm. Postoperatively, patients reported having minimal to no difficulty with 22 of 27 visual disturbances or visual activities; the other 5 items were ranked minimally to moderately difficult. The mean patient satisfaction with vision was 8.3 +/- 1.6 (out of 10); 88% of patients were spectacle independent.
  
  
  CONCLUSIONS
  Bilateral apodized diffractive aspheric multifocal IOLs with a +3.0 D add provided a broad range of optimum near vision, good intermediate visual acuity, and low rates of visual disturbances. Patients were highly satisfied with their vision, and 88% were spectacle independent.
