BACKGROUND Extracapsular cataract extraction (ECCE) with a posterior chamber intraocular lens (PC IOL) is the preferred method of cataract surgery in developed countries. However, intracapsular cataract extraction (ICCE) with an anterior chamber lens (AC IOL) may be appropriate in rural Africa. A randomised controlled trial was carried out to compare these surgical strategies. METHODS Partici...

AIM An analysis of late in-the-bag dislocation of intraocular lenses (IOL), in uveitic eyes. SETTING Referral uveitis clinic. DESIGN Retrospective case series. MATERIALS AND METHODS All case records of eyes with chronic uveitis that had phacoemulsification with IOL implantation, at a referral uveitis clinic between February 1997 and January 2015 were retrieved and analyzed. Only those eye...

PURPOSE To investigate the protective effect of a blue-light filtering intraocular lens (yellow IOL) (YA60BB, Hoya) and an ultraviolet (UV)-absorbing IOL (VA60BB, Hoya) on light-induced phototoxicity to retinal pigment epithelial (RPE) cells laden with the lipofuscin fluorophore A2E and on the production of vascular endothelial growth factor (VEGF) after light exposure. SETTING University of ...

hroughout the latter half of the twentieth century, a series of disruptive innovations and hotly debated issues resulted in general consensus for standard cataract surgery and agreement on the ideal anatomic location for intraocular lenses (IOL); namely, within the capsular bag. Sir Harold Ridley envisioned this outcome from the inception of the IOL, stating “...the site for the prosthesis shou...

PURPOSE To compare the anterior capsule contraction and intraocular lens (IOL) decentration among three types of IOL to determine the influence of haptic design on anterior capsule stability. METHODS One hundred fifty patients were enrolled in this prospective, randomized study and 260 eyes underwent implantation of one of the following IOLs: modified L-haptic IOL (n = 74), modified C-haptic ...

To improve biocompatibility of hydrophobic polymethyl methacrylate intraocular lens (PMMA IOL), 2-hydroxyethyl methacrylate (HEMA) was immobilized by UV-induced graft copolymerization method. The hydrophilicity and chemical composition of the PMMA IOL surface after each step of surfaces modification were analyzed by contact angle (CA) and X-ray photoelectron spectroscopy (XPS). The morphology o...

PURPOSE In this study, we examined the stability of the lens-angle supporter (LAS) for accommodation restoration by comparing intraocular lens (IOL) location, after-cataract and ciliary body damage after cataract surgery in rabbits. METHODS Eight rabbits were divided into experimental and control groups of four rabbits each. Phacoemulsification and irrigation and aspiration were performed in ...

PURPOSE To assess the refractive change and prediction error after temporary intraocular lens (IOL) removal in temporary polypseudophakic eyes using IOL power calculation formulas and Gills' formula. METHODS Four consecutive patients (7 eyes) who underwent temporary IOL explantation were enrolled. Postoperative refractions calculated using IOL power calculation formulas (SRK-II, SRK-T, Hoffer...

Objective: The objectives of this review were to identify the predictive factors of induction of labor (IOL) failure or success as well as to highlight the current heterogeneity regarding the definition and diagnosis of failed IOL. Materials and Methods: Only studies in which the main or secondary outcome was failed IOL, defined as not entering the active phase of labor after 24 h of prostaglan...
