To assess the depth of focus four latest non-diffractive extended range vision IOLs on optical bench. Such comparison had not been done before.We assessed and compared through modulation transfer function (MTF) following novel with a nominal power 22 D: Acrysof Vivity, LuxSmart Crystal, RayOne EMV Tecnis Eyhance. An ISO-2 model eye was applied apertures 3 4.5 mm monochromatic light 546 nm. Measurements were OptiSpheric IOL PRO 2 bench.For aperture mm, Eyhance showed most pronounced peak in...
Retropupillary fixation of an iris-claw intraocular lens (IOL) (Verisyse, Abbott Medical Optics) was performed for aphakic eyes without sufficient capsular support, and safety recovery the procedure were compared with transscleral suturing fixation.This interventional case series comprised 11 10 patients support undergoing retropupillary Verisyse, 21 20 foldable acrylic IOLs (15 14 patients, SuperFlex620H [Rayner Intraocular Lenses Ltd]) polymethylmethacrylate (6 6 CP60NS [CORNEAL...
<b><i>Introduction:</i></b> The human eye is not optically symmetrical, and very few intraocular lens (IOLs) are perfectly centered in the eye. That why contrast sensitivity can degrade some conditions, especially low light. In an optical bench analysis, we compare spherical (A), aberration correcting (B), specific aspherical lenses (C) terms of impact decentration tilt on modulation transfer function as well simulated overall quality with USAF test targets....
To compare the accuracy of thin-lens and ray-tracing methods in intraocular lens (IOL) power calculations normal eyes after corneal refractive surgery.International Vision Correction Research Centre, University Heidelberg, Germany.Pseudophakic eye models were constructed using Zemax optical software, importing radii (normal ray tracing) surface elevation data (individual measured by Pentacam Scheimpflug photography. Algorithms to predict IOL position (effective [ELP]) or postoperative...
Characteristics of the haptics and optic-haptic junction (OHJ) an intraocular lens (IOL) affect IOL position in capsular bag, positional stability, development posterior capsule opacification. Therefore, OHJ have a role determining initial long-term visual outcomes after cataract surgery. Understanding differences available IOLs relationships between each bag across range sizes might inform selection model for individuals.To evaluate geometry five currently marketed, commonly used one-piece...
The aim of the study was to analyze objective optical properties 2 enhanced depth focus (EDoF) intraocular lenses (IOLs) using bench analysis.This experimental investigates new EDoF IOLs, Alcon AcrySof IQ Vivity and Bausch & Lomb LuxSmart Crystal, on bench, OptiSpheric IOL PRO2 (Trioptics, Germany) in order assess quality according ISO 11979 with ISO-2 Cornea. IOLs (power 22.0 D) were evaluated regarding modulation transfer function (MTF) at 50 lp/mm Strehl ratio (SR) a 3.0-mm 4.5-mm...
Purpose To analyze the effect of decentration and tilt on four novel non diffractive extended range vision intraocular lenses (IOLs). Methods Acrysof Vivity, LuxSmart Crystal, RayOne EMV Tecnis Eyhance were compared optical bench (power 22 D each). Modulation transfer functions obtained Strehl ratio was calculated in an ISO-2 model. Apertures 3 mm 4.5 applied. For qualitative assessment, United States Airforce (USAF) chart images evaluated. Additional to centered IOLs, 5 degrees 1 Results...
Any new intraocular lens (IOL) on the market claims to outperform competitors. We aimed estimate modulation transfer function (MTF) for different defocus of a novel refractive enhanced depth focus (EDoF) IOL and simulated visual acuity over this range vision. Further, we analyzed wavefront pattern produced by reveal IOL's optics.
PURPOSE: To evaluate an algorithm for corneal power estimation in intraocular lens (IOL) calculation after myopic laser refractive surgery using direct measurements. SETTING: International Vision Correction Research Centre, University of Heidelberg, Germany. METHODS: Corneal parameters normal eyes and cases were evaluated by rotating Scheimpflug imaging. optical (Koptical) calculated a Gaussian optics formula was simplified as Koptical = Kanterior + K2 (Kanterior anterior power; Kposterior...
Long-term clinical results and scanning electron microscopic analysis of the aspheric, hydrophobic, acrylic intraocular lens CT LUCIA 611P(Y) Andreas F Borkenstein, Eva-Maria Borkenstein & Privatklinik der Kreuzschwestern, Graz, Austria Purpose: The aim this study was to evaluate outcomes a novel designed acrylic, monofocal, fully preloaded (IOL; 611P) 1 year after implantation. Scanning regarding optic–haptic junction sharp edges IOL performed. Patients methods: This is...
The modulation transfer functions (MTFs) of two novel enhanced depth-of-focus (EDoF) intraocular lenses (IOLs) were compared with an established diffractive EDoF IOL. Such assessment, which was not described before in the literature, is high clinical impact lens surgery.A new kind nondiffractive, wavefront-shaped IOLs has been introduced very recently to cope halos and glare known from optics. We aimed assess performance these IOL.TECNIS Symfony, AcrySof IQ Vivity, LuxSmart Crystal (22 D...
The purpose of this study was to describe our surgical experience and evaluate safety postoperative outcomes a fully preloaded, monofocal, hydrophobic acrylic intraocular lens (IOL) (CT LUCIA 611P) with newly designed optic-haptic junction in severe cases pseudoexfoliation (PXF) syndrome, phacodonesis, small pupils.This conducted Borkenstein & Borkenstein, private practice, Privatklinik der Kreuzschwestern Graz, Austria.This presents 15 eyes patients implanted CT 611P IOL improved optical...
<b><i>Purpose:</i></b> To assess differences in neodymium:yttrium aluminum garnet (Nd:YAG)-induced defects hydrophilic and hydrophobic intraocular lenses (IOLs) describe optical surface properties of YAG shots/pitting. Describing measuring the iatrogenic produced should achieve higher awareness on this topic change mindset such a trivial procedure to be proceeded with more caution calmness future. <b><i>Materials:</i></b> Twelve IOLs from...
To investigate the early and late stages of posterior vitreous detachment (PVD) in foveal area correlation with age gender.Three hundred thirty-five emmetropic eyes 271 Caucasian patients (216 women/119 men) were examined by optical coherence tomography (OCT) ultrasound (US). Eyes classified into groups according to (up 69.9; 70-74.9; 75-79.9; over 80 years) clinical findings [Vitreous state: Detached US; OCT; Foveal adhesion (FA); Attached vitreous].The mean was 76 ± 8 ranging from 44 89...
The objective of this study was to assess the rate posterior capsule opacification (PCO), under "real-life" conditions, as measured by rates Nd:YAG laser intervention, rather than from a controlled which patients with conditions predisposing PCO have been excluded.This retrospective, multicenter in an unselected consecutive cohort undergoing surgery for senile cataract. Patients aged 18 years and older, previously implanted CT LUCIA 611P IOL, were contacted at 12, 24 months ascertain if they...
