Halo and Through-Focus Performance of Four Diffractive Multifocal Intraocular Lenses.
PURPOSE To compare, as a function of pupil size, the through-focus performance and halo features of four diffractive intraocular lenses (IOLs). METHODS Three diffractive bifocal IOLs (ReSTOR +2.5 D SV25T0, Tecnis +2.75 D ZKB00, and AT LISA +3.75 D 809M) and a diffractive trifocal IOL (AT LISA tri +3.33 D, +1.66 D 839MP) were tested in vitro in a modified International Organization for Standar...
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 کاملBilateral implantation of asymmetrical diffractive multifocal intraocular lenses.
OBJECTIVE To evaluate visual results after bilateral implantation of multifocal intraocular lenses (IOLs) with asymmetrical light distribution for the far and near focus. METHODS Twenty-nine patients underwent bilateral implantation of silicone-optic, foldable, diffractive IOLs in a prospective, 2-center, noncontrolled interventional study. Each patient had a distant-dominant multifocal IOL i...
متن کاملEnergy balance in apodized diffractive multifocal intraocular lenses
The energy distribution between the distance and near images formed in a model eye by three different apodized diffractive multifocal intraocular lenses (IOLs) is experimentally determined in an optical bench. The model eye has an artificial cornea with positive spherical aberration (SA) similar to human cornea. The level of SA upon the IOL, which is pupil size dependent, is controlled using a ...
متن کاملStraylight Measurements in Two Different Apodized Diffractive Multifocal Intraocular Lenses.
PURPOSE To evaluate differences in straylight between eyes implanted with a hydrophilic multifocal IOL (Seelens MF; Hanita Lenses, Hanita, Israel) and a hydrophobic multifocal IOL (SN6AD1; Alcon Laboratories, Inc., Fort Worth, TX). METHODS In a prospective cohort study, routinely obtained straylight measurements (C-Quant; Oculus Optikgeräte, Wetzlar, Germany) 3 months after standard phacoemul...
