E-Dobson card for visual acuity

The authors assessed the utility of an electronic Dobson acuity card which can be altered for spatial frequency. Thirty-six infants and toddlers aged 5-36.7 months were recruited – equal females and males. Fourteen had high refractive error. The card is...

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...

Comparison of vision screeners

The primary purpose of this study was to calibrate the various paediatric photoscreeners over a range of contact lens induced hyperopic and astigmatic anisometropia using the American Association of Paediatric Ophthalmology and Strabismus (AAPOS) criteria for anisometropic or axial astigmatism....

Amblyopia risk factors in premature children

The purpose of this study was to determine the incidence and timing of presentation of amblyopia risk factors in premature children during the first three years of life. This was a retrospective study including 145 of 292 premature children. Retinopathy...

Visual and refractive outcomes and complications in FLACS versus CPS cataract surgery

This is a randomised, controlled study of 110 paired eyes from 55 patients that were randomised into either femtosecond laser-assisted cataract surgery (FLACS) or conventional phacoemulsification cataract surgery (CPS) groups. Visual, refractive outcomes, intraocular pressure (IOP) and complications were compared...

Lenstec welcomes the new appointment of Natalie Kempson as UK Refractive IOL Specialist to the Lenstec UK team.

DMEK vs. UT-DSAEK: has the debate been finally concluded?

In recent years the surgical treatment of corneal endothelial dystrophy has progressed tremendously. Descemet’s membrane endothelial keratoplasty (DMEK) is the newest iteration in the line of rapid surgical advances that has taken place. However, the previously accepted gold standard prior...

Optical coherence tomography – reinventing the eye examination

It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

Risk factors for further surgery in consecutive ET

The preoperative and postoperative factors around first surgery for exotropia were investigated for predicting second surgery for consecutive esotropia. Fifty-two patients with consecutive esotropia after exotropia surgery were reviewed: 17 required surgery for the esotropia and 35 did not. There...

Treatment of infantile cataract with secondary IOLs

The authors examined whether secondary IOL insertion is helpful in the successful treatment of monocular infantile cataracts. Eleven children were reviewed: eight with cataract extraction at one to four months of age and three at five to seven months of...

Changes in corneal endothelial layer after strabismus surgery

The purpose of this study was to investigate the changes in the corneal endothelial layer by specular microscopy after surgery in patients with horizontal and oblique strabismus. Eighty-three eyes of 56 patients were evaluated prospectively. There were three subgroups: one...

Life’s rich tapestry

Have you ever watched someone cross-stitch, or do needle-point? I recently had the joy of observing my teenage daughter create such an artwork. She separated all the threads into the various colours, and then started to follow the instructions carefully....
