Improving vision screening access

The purpose of this study was to determine whether providing access to instrument-based screening equipment would increase the total number of high quality age-appropriate vision screenings provided to pre-school aged children. SPOT vision screening was placed in paediatric offices at...

IOL power in short eyes

Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...

Attitudes to strabismus in an Ethiopian population

The authors conducted a community-based cross-sectional study in Gondar town (NW Ethiopia) in April 2019 of all eligible adults with a two-stage random sampling procedure for recruitment. Six hundred and two participants were included with a response rate of 94.9%...

Depth and width of corneal wounds post corneal foreign body removal

This was a prospective study of 63 eyes of 63 patients undergoing corneal foreign body (FB) removal with a 27G needle at the slit-lamp; 96.8% of the patients were men with mean age 35.8 ±11.0 years. Regarding location of FBs,...

ESCRS releases the 2022-2023 EUREQUO Annual Report

The European Society of Cataract & Refractive Surgeons is marking the 15th anniversary of the establishment of the EUREQUO Registry with the announcement that this cataract and refractive database has now grown to more than 4 million surgical procedures.

Treatment for post stroke visual impairment – clinical practice versus literature evidence

The aim of this paper is to compare the treatments reported in a large scale stroke study (Vision in stroke (VIS) Study) against the treatments identified in a full systematic literature review. The purpose was to identify which treatment /...

Laissez-faire approach for medial canthus tumours

This is a retrospective comparative case series of patients who underwent reconstruction of a medial canthal defect using laissez-faire approach (LFS), or a full-thickness skin graft (FTSG). The surgical options were discussed with the patient and the treatment decision was...

Conjunctivochalasis and aqueous tear deficiency – which one causes symptoms?

This review sought to determine whether conjunctivochalasis (CCh) obliterates the fornix tear reservoir and thus mimics aqueous tear deficiency (ATD). Patients were divided into two groups, with aqueous tear deficiency (CCh +ATD) or without (CCh –ATD), based on results of...

Who will benefit from cataract surgery?

The need for cataract surgery is expected to rise dramatically in the future due to the increasing proportion of elderly citizens and increasing demands for optimum visual function. The aim of this study was to provide an evidence-based recommendation for...

Diabetic polyneuropathy and risk of developing diabetic retinopathy

Diabetic polyneuropathy (DPN), diabetic retinopathy (DR) and diabetic nephropathy are widely classified as microvascular complications of diabetes. DPN, which may cause complete sensation loss, is another common complication of DM. The DPN-related diminished sensation presents a significant risk factor for...

VEGF and axial length (RVU)

The authors of this paper set out to examine whether the concentrations of VEGF in the vitreous were associated with refractive error and axial length in eyes without retinal disease, except of macular holes or epiretinal membranes. A vitreous sample...

Practical phacodynamics – making the most of your phacoemulsification machine

Understanding phacodynamics is appreciating the subtleties in the dynamic changes of the fluidics and the ultrasonic power delivered. Kristina Southcott explains. Increase my vacuum! Increase my bottle height! Increase my phaco power! I frequently observe the above commands being directed...
