title: Visual and optical performances of multifocal intraocular lenses with three different near additions: 6-month follow-up.
abstract: OBJECTIVE
  To compare the visual and optical outcomes of four multifocal intraocular lenses (IOLs) with three different near additions of +3.00 diopters (D), +3.75 D and +4.00 D.
  
  
  METHODS
  In this prospective study, 133 eyes of 88 patients were implanted with one of the following IOLs: AcrySof(®) ReSTOR(®) SN6AD1 (+3.00 D) for Group A, Acriva(UD) Reviol BB MF 613 or BB MFM 611 (+3.75 D) for Group B, and AcrySof(®) ReSTOR(®) SN6AD3 (+4.00 D) for Group C. The visual acuity, refraction, intraocular pressure, tomography and corneal endothelial cell density (ECD) were compared between the three groups preoperatively and at 6 month postoperatively. Defocus curve, contrast sensitivity and higher order aberrations (HOAs) at 6 month postoperative visit were measured and compared.
  
  
  RESULTS
  There were no statistically significant differences in distance visual acuity, refraction, intraocular pressure or ECD among the three groups after 6 months (P > 0.05). The photopic contrast sensitivity in Group C was statistically better than in Group A (P < 0.05). The scotopic ocular aberration in Group B was statistically greater compared to that in Group A (P < 0.05). The highest near-visual peaks were -0.06 logMAR at a -2.50 D (40 cm) in Group A, -0.07 logMAR at -3.00D (33 cm) in Group B, and -0.06 logMAR at -3.50 D (29 cm) in Group C. Statistically significant differences in near and intermediate visual acuities were observed among the three groups at -2.00 D (50 cm), -2.50 D (40 cm), -3.50 D (29 cm) and -4.00 D (25 cm) (P < 0.01).
  
  
  CONCLUSIONS
  AcrySof(®) ReSTOR(®) SN6AD1 IOLs (+3.00 D) and SN6AD3 (+4.00 D) IOLs provided the best intermediate and near vision, respectively. Both intermediate and near vision were comparatively better in the eyes with Acriva(UD) Reviol BB MFM 611 IOLs or BB MF 613 IOLs (+3.75 D).
