متن کاملComparison of Visual Performance of Multifocal Intraocular Lenses with Same Material Monofocal Intraocular Lenses
PURPOSE To compare the visual performance of multifocal intraocular lenses (IOLs) and monofocal IOLs made of the same material. METHODS The subjects included patients implanted with either Tecnis® monofocal IOLs (ZA9003 or ZCB00) or Tecnis® multifocal IOLs (ZMA00 or ZMB00) bilaterally. We conducted a retrospective study comparing the two types of IOLs. The multifocal group included 46 patient...
