Open-field autorefraction screening

This study aimed to determine the efficacy of the Shin-Nippon NVision-K5001 autorefractometer using the open-field refractometry principle in the elimination of accommodation in children. One hundred and fourteen patients aged three to six years were recruited. After excluding ocular pathology...

Posterior capsular rupture risk factors as reported in the European registry

In this cross-sectional review of the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) including 2,853,376 patients and 31,749 cases with posterior capsular rupture (PCR), the authors observed a trend of reduction in PCR rate from 1.44%...

Complex Biometry Clinics: a new service development

In this article we describe a new local service development, the ‘Complex Biometry Clinic’ at Leicester Royal Infirmary. Retrospective data analysis of patients referred between October 2012 and October 2013 was performed. The aim was to provide a one-stop service...

Surgical options for the treatment of hyperopia

The modern refractive surgeon has a variety of options available to treat patients with hyperopia who wish to be independent of spectacles and contact lenses. Unlike in low myopia where presbyopic patients may have the ability to see well for...

Secondary intraocular lens implantation in children

This is a retrospective study of the medical records of children under the age of 16 who underwent secondary lens implantation for aphakic corrections after previous congenital cataract surgery over a period between January 2000 and December 2010. The study...

Optical quality difference between monofocal and multifocal intraocular lenses

It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...

Clinical evaluation of a new pupil independent diffractive MIOL lens with a ±2.75D near addition

This is a clinical outcome assessment after cataract surgery with implantation of multifocal intraocular lens implant IOL with a lower near addition (+2.75D) of 143 eyes of 85 patients aged between 40 to 83 years of age. The type of...

World Optometry Day 2022

Today, Wednesday 23rd March, is #WorldOptometryDay. A day to celebrate the global community of optometrists and all the eye care professionals that support the ophthalmic health and wellbeing of many millions of patients.

Hyper reflective foci (HRF) on OCT in diabetic retinopathy

This study investigated the presence of hyper reflective foci (HRF) in asymptomatic patients affected by type 1 or type 2 diabetes, separately, without clinically significant diabetic macular oedema and visual impairment. In total 71 eyes with non-proliferative diabetic retinopathy were...

OVD influences

This prospective case series provides data on a previously uninvestigated area. Eyes due to have routine phakoemulsification were divided into six groups according to ophthalmic viscosurgical device (OVD) type. After cataract extraction aphasic refraction using intraoperative aberrometry with the ocular...

Refraction under GA in children using cycloplegic refraction as a reference

The authors aimed to compare the measurements of cycloplegic refraction and refraction (R1-1) under general anaesthesia (GA) with automated refraction (ARF) in paediatric patients and to determine the impact of GA on accommodation. The study included 222 eyes of 222...

Myopia rate of change from 5-20 years

Data was collected from the 2008-12 KNHANES survey and the study included 7695 of 9351 subjects with refractive data. The mean age was 11.8 years (5-20 range) with 48.2% female. Mean spherical equivalent was -1.82 ±2.23D. For five-year-olds, the mean...
