title: [Quality of vision in eyes that underwent implantation of ReSTOR apodized diffractive multifocal intraocular lens on bilateral eyes in cataract surgery].
abstract: OBJECTIVE
  To compare the visual outcomes and subjective parameters in patients who underwent implantation of ReSTOR apodized diffractive multifocal intraocular lens on bilateral eyes with those in patients who had monofocal intraocular lens in cataract surgery.
  
  
  METHODS
  Retrospective observational case series. 50 eyes of 25 patients received ReSTOR multifocal intraocular lens (multifocal group) and 56 eyes of 28 patients taken implantation of Natural monofocal intraocular lens (monofocal group) participated in the study. The distance and near visual acuity were compared, as well as contrast and glare sensitivity. Visual symptom and spectacle dependence were assessed using a standardized questionnaire. The minimal follow-up was 3 months.
  
  
  RESULTS
  An uncorrected distance visual acuity of 0.6 or better was achieved in 94% of eyes in multifocal group and 96% in the monofocal group, respectively (chi(2) = 0.347, P > 0.05). Uncorrected near visual acuity was J(3) or better in 88% of eyes in the multifocal group and 13% in the monofocal group (chi(2) = 60.315, P < 0.01). Best distant corrected near visual acuity was Jr3 or better in 90% of eyes in the multifocal group and 11% in the monofocal group (chi(2) = 66.515, P < 0.01). No significant difference in contrast and glare sensitivity was found between the groups (P > 0.05). Glare was reported as severe in 12% of the multifocal group and 7% of the monofocal group, respectively (chi(2) = 0.365, P > 0.05). Halo was reported as severe in 8% of the multifocal group and 4% of the monofocal group, respectively (chi(2) = 0.485, P > 0.05). 96% of patients in both groups never had to wear glasses for the distant purpose (chi(2) = 0.007, P > 0.05), and 80% in multifocal group and 11% in monofocal group never had to wear glasses for the near purpose (chi(2) = 25.811, P < 0.01).
  
  
  CONCLUSIONS
  The ReSTOR apodized diffractive intraocular lens provided predictably excellent uncorrected distance and near visual acuities, and obtained satisfactory quality of vision. Spectacle independence was significantly higher with this multifocal intraocular lens.
