Influence of overall intraocular lens diameter on rotational stability

It has been shown that approximately one in three patients undergoing cataract surgery have >1.0D corneal astigmatism and managing this during surgery is important to achieve good refractive outcomes. One of the widely used ways of reducing preoperative astigmatism during...

Intraocular surgical training – is there any inter-procedural transfer of skills?

Cataract surgery is the most commonly performed surgery during ophthalmology training. This study aims to investigate how experience in simulated cataract surgery impacts and transfers to the learning curves for novices in vitreoretinal surgery. Twelve ophthalmology residents without previous experience...

IOL cataract surgery 7-24 months

The purpose of this study was to present the long-term outcome of IOLs in paediatric patients who received cataract surgery aged seven to <24 months. This was retrospective study with minimum follow-up of 12 months for 27 patients (28 eyes)....

Effects of topical anaesthetic on intraocular pressure

This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

High myopes with POAG and IOP fluctuations

The authors describe a prospective study of 80 eyes of Chinese patients with primary open-angle glaucoma (POAG) on prostaglandin analogues to investigate if those who also have high myopia exhibit greater short-term intraocular pressure (IOP) fluctuations at resting conditions over...

Randomised trial of multifocal intraocular lens versus monovision

The authors report on a randomised, multicentre clinical trial comparing the outcomes of Tecnis ZM900 diffractive multifocal intraocular lenses (IOL) versus monovision with Akreos AO monofocal IOL (dominant eye targeted for emmetropia and non-dominant eye targeted for -1 to -1.50...

Two bifocals and a trifocal

The authors compare the optical outcomes of two bifocal intraocular lenses (AcrySof ReSTOR +2.50 Diopter [D] add +3.0D add) with a trifocal lens (AT LISA tri 839MP). The optical qualities of the lenses were quantified by measuring the modulation transfer...

Rotational stability of angle supported phakic IOL

The authors evaluate 50 eyes of 28 patients that underwent an angle fixated phakic intraocular lens (IOL) implantation (Acrysof Cachet). All eyes had moderate to high myopia (-5.25 to-19.63 dioptres) and IOL sizing was performed as per the manufacturer’s recommendation....

Under pressure: intraocular pressure and bariatric surgery

Obesity in the general patient population is increasing. The National Institute for Health and Care Excellence recommends bariatric surgery with body-mass index (BMI) of over 40, or between 35-40 and other significant disease that could be improved with weight loss....

Effect of phacoemulsification on facility of outflow

This is a prospective study to examine the change in electronic Schotz tonographic outflow (TOF) and IOP measurements after phacoemulsification. Intraocular pressure was measured using Goldman‘s applanation tonography (GAT). Data were collected at baseline, three, six and 12 months postoperatively....

Delayed angle closure in pseudophakia and repeated intravitreal therapy

The authors report two cases of acute angle closure many years after uneventful cataract surgery and posterior chamber intraocular lens (IOL) implantation. Both patients had neovascular age-related macular degeneration (AMD) and received regular intravitreal injections (24 and 25 injections in...
