PURPOSE To analyze the indications for explantation or exchange of intraocular lenses (IOLs), which were originally implanted for the correction of aphakia during cataract extraction. METHODS All cases that involved intraocular lens explantation or exchange in one institution between January 2008 and December 2014 were analyzed retrospectively. RESULTS In total, 93 eyes of 93 patients were ...

purpose: to compare the results of implantation of intraocular lens (iol) haptics in ciliary sulcus versus optic capture through the posterior capsulorrhexis following iol implantation in capsular bag in pediatric cataract surgery. methods: eighteen eyes of nine children with bilateral congenital or developmental cataract were included in this contralateral prospective randomized study. all cas...

PURPOSE To evaluate higher order aberrations and contrast sensitivity after LASIK, implantation of the Verisyse phakic intraocular lens (IOL), and refractive lens exchange with the Array multifocal IOL. METHODS In a prospective, non-randomized case series, LASIK was performed in 20 eyes with the Technolas 217z excimer laser (Bausch & Lomb, Rochester, NY), a Verisyse phakic IOL (AMO Inc, Santa...

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...

PURPOSE To evaluate whether the Tecnis Z9000 intraocular lens (IOL) (Pfizer) with a modified prolate anterior surface provides better quality of vision than a conventional spherical IOL. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS Patients presenting for cataract surgery who were randomly assigned to receive a Tecnis Z9000 IOL (Pfizer) or a Sensar OptiEdge AR40e IOL (AMO) in ...

OBJECTIVE To evaluate the prevalence, indications, and factors associated with successful induction of labor (IOL), and maternal and neonatal outcomes. METHODS All women booked for IOL at King Khalid University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia from April 2010 to March 2011 were included. The characteristics of women who had successful IOL were compared to those ...

PURPOSE To establish a fully human in vitro culture model with which to test the putative effects of intraocular lens (IOL) designs in preventing posterior capsule opacification (PCO) after cataract surgery. METHODS A sham cataract operation was performed to prepare human capsular bags from donor lenses. In one capsular bag of a donor pair, an intraocular lens (PMMA round-edge IOL or acrylic ...

Purpose To compare surgically induced astigmatism (SIA) and refractive outcomes between two operation methods for late in-the-bag IOL dislocation. Methods In this prospective, randomized, parallel-group clinical trial, 104 patients (eyes) were assigned to IOL repositioning by scleral suturing 1.5- to 2-mm posterior to limbus (n = 54) or IOL exchange with a retropupillar iris-claw IOL using a ...

BACKGROUND Intraocular lymphoma (IOL) is a rare malignant lymphoma that most closely resembles a diffuse large B-cell lymphoma, and it is a subtype of primary central nervous system lymphoma (PCNSL). IOL is located inside the eye in the retina, uvea, and/or optic nerve. We retrospectively analyzed IOL patient data to identify treatment patterns and survival rates in Korea. METHODS Cytological...

PURPOSE To evaluate blue-light attenuation in eyes with a tinted intraocular lens (IOL) or an untinted IOL. SETTING Department of Ophthalmology, University Hospital of Crete, Crete, Greece. DESIGN Comparative case series. METHODS Patients had lens extraction and implantation of an Acrysof Natural tinted or Tecnis ZA9003 or Softec III untinted acrylic IOL. The luminance ratio of green (530...
