Optical bench performance of a novel trifocal intraocular lens compared with a multifocal intraocular lens
PURPOSE The purpose of this study is to compare the optical characteristics of the novel PanOptix presbyopia-correcting trifocal intraocular lens (IOL) and the multifocal ReSTOR +3.0 D IOL, through in vitro bench investigations. METHODS The optical characteristics of AcrySof(®) IQ PanOptix™ (PanOptix) and AcrySof(®) IQ ReSTOR +3.0 D (ReSTOR +3.0 D) IOLs were evaluated by through-focus Badal i...
متن کاملOptical quality of toric intraocular lens implantation in cataract surgery.
AIM To analyze the optical quality after implantation of toric intraocular lens with optical quality analysis system. METHODS Fifty-two eyes of forty-four patients with regular corneal astigmatism of at least 1.00 D underwent implantation of AcrySof toric intraocular lens, including T3 group 19 eyes, T4 group 18 eyes, T5 group 10 eyes, T6 group 5 eyes. Main outcomes evaluated at 3mo of follow...
متن کاملEvaluation of Optical Quality Parameters and Ocular Aberrations in Multifocal Intraocular Lens Implanted Eyes
PURPOSE We investigated the correlations between optical quality parameters obtained from the double-pass system and ocular aberrations obtained from the ray-tracing aberrometer in multifocal intraocular lens (IOL) implanted eyes. MATERIALS AND METHODS Twenty eyes from 20 patients were enrolled in this study. Modulation transfer function cutoff frequency, The Strehl ratio, objective scatter i...
متن کاملevaluation of the impact of intraocular lens tecnis z9000 misalignment on the visual quality using the optical eye modeling
purpose : the aim of this study was to investigate the effect of misalignment (tilt & decentration) of iols in cataract surgery using liu-brennan optical eye model in a simulation. methods : a phantom with the real eye parameters –liu-brennan model– and tecnis z9000 iol were used for simulation. results : results showed that with 0.4 mm decentration and more the modulation transfer function (mt...
متن کاملInfluence of glistenings on the optical quality of acrylic foldable intraocular lens.
AIMS To assess the influence of glistenings on the optical quality of acrylic foldable intraocular lens. METHODS Several degrees of glistenings in the optic were experimentally created by immersing the lens in water at 37 degrees C for 48 hours and then at 25 degrees C for 24 hours. Optical bench tests were carried out in water including measurements of spectral transmittance with the spectro...
