PURPOSE To investigate the effect of yellow tinted intraocular lenses (IOLs), implanted in the bag after phacoemulsification, on the result of frequency doubling technique (FDT) perimetry. METHODS For 68 eyes of 52 patients, an IOL was implanted in the bag after phacoemulsification. The patients were categorized into three groups according to the type of implanted IOLs used. IOLs were selecte...

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 ...

PURPOSE To assess the accuracy of intraocular lens (IOL) power prediction for cataract surgery with open angle glaucoma (OAG) and to identify preoperative angle parameters correlated with postoperative unpredicted refractive errors. MATERIALS AND METHODS This study comprised 45 eyes from 45 OAG subjects and 63 eyes from 63 non-glaucomatous cataract subjects (controls). We investigated differe...

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 To study a paired-match comparison between refractive lens exchange with pseudophakic IOL implant (RLE) and Artisan phakic IOL for high hyperopia. METHODS Nineteen eyes (12 patients, 20 to 41 years old) with an Artisan phakic IOL (Model 203: 1.00-D increment) for hyperopia from +2.75 to +9.25 D were matched to 19 eyes (15 patients, 26 to 46 yr) with hyperopia from +2.75 to +7.50 D, wh...
