Through focus image quality of eyes implanted with monofocal and multifocal intraocular lenses
Intraocular lenses (lOLs) are commonly implanted in cataract surgery. Initially lOLs were mainly monofocal, but at present there are many multifocal lOLs available, which are being implanted. Multifocal lOLs have the potential advantage of reducing the dependence on spectacle correction for near vision after cataract surgery. Because the multifocal lOLs superimpose the near and far images on th...
متن کاملComparative visual performance with monofocal and multifocal intraocular lenses
BACKGROUND To compare near, intermediate, and distance vision, and quality of vision using appropriate subjective questionnaires, when monofocal or apodized diffractive multifocal intraocular lenses (IOLs) are binocularly implanted. METHODS Patients with different binocular IOLs implanted were recruited after surgery and had their visual acuity tested, and quality of vision evaluated, at a si...
متن کاملCorneal optical aberrations and retinal image quality in patients in whom monofocal intraocular lenses were implanted.
OBJECTIVES To compare retinal image quality and optical corneal aberrations in patients in whom monofocal polymethyl methacrylate intraocular lenses (IOLs) were implanted with those in healthy subjects of a similar older age (60-70 years old) and to use the results to suggest improved optical designs of IOLs to maximize retinal image quality. METHODS A double-pass apparatus was used to measur...
متن کاملDisk halo size measured in individuals implanted with monofocal versus diffractive multifocal intraocular lenses
METHOD: Halo radius was measured using a vision monitor (MonCv3) with low-luminance optotypes in 39 eyes that had cataract surgery and the bilateral implant of an Acrysof Restor SN6AD1 multifocal IOL or Acrysof IQ monofocal IOL 6 to 9 months previously. The visual angle subtended by the disk halo radius was calculated in minutes of arc (arcmin). Patient complaints of halo disturbances were reco...
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...
