Changes in axial length and refraction in young Chinese school children

The authors aimed to assess refractive error and axial length in children aged seven to eight years (grades 1-2) starting education in South China. The study reviewed 301 students and obtained data for analysis from 291 (50.2% female). Average axial...

Spot screener versus Grand Seiko measurements

The authors aimed to determine repeatability and reproducibility of refractive values and pupil size measured using the Spot Vision Screener and to compare its measurement values with the Grand Seiko autorefractor. This was a cross-sectional study of 22 healthy adults;...

Biomechanical stabilisation of ocular measurements post cataract surgery

This prospective study looks into the time duration of biomechanical stabilisation post uneventful cataract surgery in a case series of 62 consecutive eyes in patients with no ocular or systemic comorbidity. The patients were followed-up at fixed intervals of one...

Photoscreener use in pseudophakia

The purpose of this study was to compare refractive data obtained by the Plusoptix and SPOT to data obtained during masked paediatric ophthalmic examinations with retinoscopy in 44 pseudophakic eyes of 44 children. The average age at measurement was 7.4...

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...

Change in hyperopia with strabismus

This study aimed to evaluate hyperopic evolution patterns in children with early diagnosis (before three years) and treatment. This was a retrospective study of 78 eyes of 39 children. Forty-nine percent were males and mean follow-up was 130 months (72-193)....

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...

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...

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...

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...

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...
