PURPOSE It has been shown that the biggest dissatisfier for uncomplicated cataract surgery patients is pseudophakic dysphotopsia (PD). While edge design of an intraocular lens (IOL) impacts this problem, refractive index is still controversial as to its impact. This retrospective cohort study was designed to determine the role of increasing refractive index in PD. PATIENTS AND METHODS This st...

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...

BACKGROUND The purpose of this study was to evaluate the correlation between contrast sensitivity and calculated higher-order aberrations based on individual natural pupil diameter after cataract surgery. METHODS This prospective study included 120 eyes from 92 patients who were randomized to receive one of four lenses, including three aspheric lenses (Acrysof SN60WF, Tecnis ZA9000, and Hoya ...

Purpose To evaluate the outcomes following bilateral ERV intraocular lens implantation with micromonovision. Methods 25 subjects underwent bilateral Tecnis Symfony IOL implantation with micromonovision. The dominant eye was targeted for emmetropia and the nondominant eye for myopia of -0.75 D. Uncorrected and corrected distance (UDVA, CDVA), intermediate (UIVA, CIVA), and near visual acuity (...

PURPOSE To assess the differences in optical performance of 9 multifocal IOLs using the same optical bench and to propose a possible comparison for surgeons. SETTING Rothschild Foundation, Paris, France. DESIGN Experimental study. METHODS Nine IOLs (Acrysof Restor +3.0 diopter [D] SN6AD1, Acrysof Restor +4.0 D SN60D3, Acrysof aspheric monofocal SN60WF, Acri.Lisa 366D, Finevision Micro F, ...

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...
