Disk 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 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 کاملOptical performance of monofocal versus multifocal intraocular lenses.
In their recent paper, Ortiz et al. studied the optical performance of monofocal and multifocal intraocular lenses (IOLs) in the human eye. Their main conclusion was that of the IOLs studied, the hybrid refractive–diffractive IOLwas the least affected by pupil diameter in terms of intraocular aberrations. This IOL type also showed a smaller increase in optical aberrations during pupil dilation....
متن کاملVisual Outcomes After Cataract Surgery: Multifocal Versus Monofocal Intraocular Lenses.
PURPOSE To evaluate visual outcomes, spectacle independence, and quality of life among nonastigmatic and astigmatic patients who received AcrySof IQ ReSTOR toric or nontoric multifocal intraocular lenses (IOLs) (Alcon Laboratories, Fort Worth, TX) compared with those who received commercially available nontoric monofocal IOLs after bilateral cataract removal. METHODS This randomized, patient-...
متن کاملMultifocal versus monofocal intraocular lenses after cataract extraction.
BACKGROUND Good unaided distance visual acuity is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation. Near vision however still requires additional refractive power usually in the form of reading glasses. Multiple optic (multifocal) IOLs are available which claim to allow good vision at a range of distances. It is unclear whether this benefit outweigh...
