PURPOSE To assess the performance and optical limitations of standard, aspheric, and wavefront-customized intraocular lenses (IOLs) using clinically verified pseudophakic eye models. METHODS White light pseudophakic eye models were constructed from physical measurements performed on 46 individual cataract patients and subsequently verified using the clinically measured contrast sensitivity fu...

PURPOSE To determine the amplitude of pseudoaccommodation and higher-order aberrations with three types of implanted monofocal intraocular lenses (IOLs): aspheric yellow (IQ); spheric yellow (NT); and spheric clear (AT). SETTING Department of Ophthalmology, Nara Medical University, Nara, Japan. METHODS We studied 60 patients who underwent small incision phacoemulsification with the implanta...

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 ...

Reading is the most common goal among persons with age-related macular degeneration and other retinal diseases that lead to macular loss, as well as the functional task most affected by the resulting central scotomas. This project determined whether reading ability is different when persons with macular loss read with a new hybrid-diffractive spectacle magnifier versus a refractive-aspheric spe...

PURPOSE To demonstrate differences in human lens epithelial cell adhesion to different intraocular lens biomaterials in vitro and to determine whether these differences can be influenced by coating the intraocular lens surface with commercially available fibronectin. METHODS A prospective laboratory-based study comparing human lens epithelial cell adhesion to silicone (n=18), polymethylmethac...

Purpose To evaluate the influence of Intraocular Lens (IOL) material and design on Posterior Capsule Opacification (PCO) and Neodymium-YAG (Nd-YAG) rates in eyes implanted with different Posterior Chamber Intraocular Lenses (PC IOLs) designs at the end of uncomplicated cataract surgeries. Setting Oculus Eye Clinic, Bucharest, Romania. Design Retrospective, observational study. Methods Thi...
