Purpose. To report visual outcomes and patient satisfaction after unilateral or bilateral refractive lens exchange (RLE) with a single-piece bifocal diffractive multifocal intraocular lens (MIOL). Methods. All patients underwent RLE with the ZMB00 MIOL (Abbott Medical Optics). Patient charts were reviewed to evaluate the distance, intermediate, and near visual acuity (VA), contrast sensitivity,...

PURPOSE To evaluate refractive and visual parameters related to distance, intermediate, and near vision after cataract surgery and the optical quality of a new diffractive trifocal intraocular lens (IOL). SETTING Vissum Instituto Oftalmologico de Alicante, Alicante, Spain. DESIGN Case series. METHODS Patients had bilateral refractive lens exchange and multifocal diffractive IOL (AT Lisa t...

BACKGROUND To evaluate binocular visual outcome for near, intermediate and distance compared to monocular visual outcome at the same distances in patients implanted with a diffractive trifocal intraocular lens (IOL). METHODS The study comprised of 100 eyes of 50 patients that underwent bilateral refractive lens exchange or cataract surgery with implantation of a multifocal diffractive IOL (AT...

The cornea is the main refractive surface of the eye. The prolate shape of the cornea plays a role in maintaining the optimum total spherical aberration (SA) of the eye by neutralizing the negative SA of the lens. As we age the lenticular SA shifts in the positive direction while the corneal SA remains the same, making the total ocular SA more positive. SA of the eye is directly proportional to...

PURPOSE The aim of this study was to assess visual and refractive outcomes of laser vision correction (LVC) to correct residual refraction after multifocal intraocular lens (IOL) implantation. PATIENTS AND METHODS In this retrospective study, 782 eyes that underwent LVC to correct unintended ametropia after multifocal IOL implantation were evaluated. Of all multifocal lenses implanted during ...

Objectives To assess the visual outcomes in patients who underwent cataract surgery with multifocal intraocular lens (IOL) implantation using a "mix and match" approach. Materials and Methods Twenty patients (40 eyes) were involved in this prospective, nonrandomized study. Refractive multifocal IOLs (ReZoom NXG1) were implanted in patients' dominant eyes and diffractive multifocal IOLs (Tecni...

PURPOSE To evaluate and compare the visual acuity outcomes and optical performances of eyes implanted with two diffractive multifocal intraocular lens (IOL) models with either a plate haptic design or a modified-C design. METHODS This retrospective study comprised cataract patients who were implanted with either a plate haptic multifocal IOL model (Acriva(UD) Reviol BB MFM 611 [VSY Biotechnol...

PURPOSE To compare the clinical outcome of different multifocal intraocular lenses (IOLs) based on information reported in the international literature. METHODS All comparative clinical trials that involved implanting at least one multifocal IOL in patients with cataract or presbyopia were extracted from the literature. Clinical outcomes included uncorrected near visual acuity, uncorrected di...

PURPOSE The study evaluated-theoretically and experimentally-the longitudinal chromatic aberration (LCA) and through-focus energy efficiency (TF-EE) of diffractive-refractive bifocal intraocular lenses (2f-IOLs). METHODS Four aspheric 2f-IOLs (Tecnis +4.00 diopter [D] ZMA00, +2.75 D ZKB00, and AcrySof +4.0 D SN6AD3, +2.5 D SV25T0) of same base power 30 D, but different design, additional (add...

The new generation multifocal lenses provide the surgeon with several options to meet the specific visual needs and desires of patients. A revolution in presbyopia surgery is being driven by two multifocal intraocular lenses, ReStor and ReZoom. Combined implantation of the ReZoom multifocal lens in nondominant eye and ReStor multifocal lens in dominant eye has been demonstrated to produce stati...
