Single vs combined y-split surgery for Duane’s type III

The authors present the results of two surgical approaches to treat exotropia Duane’s retraction syndrome (DRS) with significant overshoot and retraction. This study compared single Y-split recession of the lateral rectus muscle vs combined Y-split lateral rectus recession plus medial...

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)....

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...

Moorfields International refractive symposium

The Moorfields International refractive symposium covers contemporary vision correction surgery to surgeons in the UK and around the world. Taking place on Thursday 24 April at the Royal College of Physicians in London (08:30 - 17:45), the symposium aims to...

Childhood headaches

The goal of this study was to compare headache resolution in children receiving or not receiving refractive correction. The authors conducted a retrospective review of 158 patients: 78 male and 80 female aged three to twelve years (mean eight). Twenty-seven...

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;...

Refractive changes after surgery

A long-term follow-up study was conducted to report power vector analysis of refractive astigmatic changes in a large group of 137 patients (250 eyes) undergoing horizontal strabismus surgery. Fifty-four percent were male. The average age was 9.22±8.21 years. Fifty-five percent...

Bilateral LR recession for DRS

This study reports the use of bilateral lateral rectus (LR) recessions instead of unilateral LR recession for unilateral exotropic Duane’s retraction syndrome (DRS) with abnormal head posture. This was a retrospective study of seven patients; five female and two male....

BT outcomes for accommodative esotropia

The purpose of this study was to study the effect of Botulinum Toxin (BT) in refractive and non-refractive accommodative esotropia unresponsive to glasses and poor compliance with glasses. This was a retrospective study of 114 patients who had BT for...

Refractive surprise after cataract surgery caused by posterior capsular striae

Cataract removal with intraocular lens (IOL) implantation is one of the most frequently performed surgeries in current clinical practice [1,2]. New microsurgical techniques and refined IOL power calculations allow excellent refractive outcomes. Refractive surprise following cataract surgery is uncommon [1-3]...

Introduction to Visual Optics: A Light Approach

In Introduction to Visual Optics: A Light Approach, Samantha Strong brings fresh life to a traditionally dense topic, making optics accessible, engaging, and even enjoyable. With a conversational tone and clear organisation, Strong guides readers through complex concepts in a...

Intermittent exotropia

Four cases of intermittent exotropia are discussed. Case 1 was a nine-month-old with cycloplegic refraction of +1.0DS and a 30PD intermittent exotropia at near and distance. Discussions considered observation, part-time occlusion, refractive correction and later possibility of surgery. Case 2...
