OBJECTIVES To examine interhospital variation in rates of induction of labour (IOL) to identify potential targets to reduce high rates of practice variation. DESIGN Population-based record linkage cohort study. SETTING New South Wales, Australia, 2010-2011. PARTICIPANTS All women with live births of ≥24 weeks gestation in 72 hospitals. PRIMARY OUTCOME MEASURE Variation in hospital IOL r...

PURPOSE To compare the optical performance of 6 presbyopia-correcting intraocular lenses (IOLs) of different designs (accommodating or multifocal and aspheric or spheric). SETTING Alcon Laboratories, Inc., Fort Worth, Texas, USA. METHODS The optical performance of 6 IOLs were compared using modulation transfer function (MTF) and the United States Air Force 1951 Resolution Target (AFT) testi...

BACKGROUND To report two cases of Descemet Membrane Endothelial Keratoplasty (DMEK) in patients with existing scleral-fixated and iris-fixated intraocular lenses (sf-IOL and if-IOL, respectively). CASE PRESENTATION DMEK procedures were performed on a 49-year-old woman with a pre-existing sf-IOL (case 1) and a 69-year-old woman with a pre-existing if-IOL (case 2) in order to treat secondary co...

PURPOSE The purpose of this study was to provide clinical outcomes data related to secondary intraocular lens (IOL) implantation for the correction of residual refractive error after cataract surgery. PATIENTS AND METHODS A chart review was conducted to identify all eyes implanted with the monofocal spherical or toric AddOn® secondary IOL. Data were collated from charts where uncomplicated in...

OBJECTIVE We retrospectively analyzed the visual results and postoperative complications associated with severely traumatized eyes in which aphakia was corrected with epikeratophakia or a sutured iris prosthesis/intraocular lens (IOL). METHODS Fourteen eyes (14 patients) with traumatic aphakia and severe anterior segment complications were corrected either with epikeratophakia or a sutured ir...

PURPOSE To compare the rotational stability and posterior capsule opacification (PCO) rate in eyes with a 1-piece or 3-piece acrylic intraocular lens (IOL). SETTING Department of Ophthalmology, Medical University of Vienna, Vienna, Austria. DESIGN Prospective randomized masked clinical trial. METHODS Patients with age-related cataract received a plate-haptic acrylic IOL (Acri.Smart 46S) i...

AIMS To compare optotype acuities and re-operation rates in children corrected with a contact lens (CL) compared with an intraocular lens (IOL) following unilateral cataract extraction during infancy in a non-randomised, retrospective case series. METHODS 25 infants with a unilateral congenital cataract underwent cataract surgery with (IOL group, n = 12) or without (CL group, n = 13) IOL impl...

PURPOSE To compare the accuracy of intraocular lens (IOL) power calculation methods for post-myopic excimer laser surgery patients without previous refractive surgery data using the Holladay IOL Consultant Program and the American Society of Cataract and Refractive Surgery (ASCRS) IOL Power Calculator. SETTING Wang Vision Cataract and LASIK Center, Nashville, Tennessee, USA. DESIGN Case ser...

Purpose: To investigate the interocular difference of axial length (AL), mean keratometry (K), corneal astigmatism and anterior chamber depth (ACD) according to AL without history ocular surgery.Methods: This study was performed on 16,411 patients (32,825 eyes) who were measured AL, K, ACD by IOL Master® from April 2007 September 2016, excluding with missing values extreme in AL. After, divided...
