How increasing school leaving age influences myopia in adulthood

By paulgifford | October 16, 2020 | 0 Comments

Education and myopia have had a long association, both anecdotally and from research findings with studies in general finding strong correlations with education and prolonged close work rather than a definite causative link. This study investigated the impact of education on refractive error by examining the relationship between increasing the school leaving age and myopia.

Axial length growth and the risk of developing myopia in European children

By paulgifford | September 22, 2020 | 0 Comments

This population-based study set out to produce a percentile growth chart for axial length based on the data collected from European children and adults, and in doing so they found a stronger correlation between the refractive error and axial length in myopes compared to the same measurements in emmetropes.

Accommodation is unrelated to myopia progression in Chinese myopic children

By implementing analysis across a continuous range of accommodation between 0 and 6.00D, and including distance accommodation facility, the authors investigated the relationship between accommodation and myopic progression in Chinese myopic children.

Prevalence of myopia among disadvantaged Australian schoolchildren

This retrospective analysis of refraction in low socioeconomic children from rural New South Wales and Australian Central Territory, Australia, reveals lower prevalence of myopia compared to reports from urban areas.

Race as a predictor of myopia progression in paediatric patients; Scleral cross-linking using Rose Bengal green light; Blink study results; Vision with multifocal CL in myopes and presbyopes; Influence of CN multifocal CL on VA in young myopes and presbyopes; Effect of high add OK lens designs on corneal hysteresis and ocular aberrations.

Evaluating on-eye wavefront aberrations of a soft contact lens with an optical design simulating orthokeratology

By paulgifford | August 25, 2020 | 0 Comments

Prototype soft CLs designed to replicate the optical profile induced by OK were found to provide similar whole eye wavefront aberration measurements at distance and near fixation to existing OK lens wearers.

Evaluation of simulated orthokeratology in a soft contact lens for myopia control

By paulgifford | August 25, 2020 | 0 Comments

Soft contact lenses designed to simulate the change in refraction optical pro-file from orthokeratology (OK) fail to slow axial eye elongation or change to refrac-tion over 1-year of wear in children, leading to suggestion that OK’s propensity to slow myopia progression may not be due to changes OK makes to optical profile.

BLINK study results: comparing +1.50 vs +2.50 add multifocal contact lenses for myopia control

By paulgifford | August 12, 2020 | 0 Comments

The much anticipated BLINK study has just been published! Hot off the press, we examine the results comparing +1.50 and +2.50 centre distance MFCLs, explain the study and describe how these results compare to other myopia controlling contact lenses.

Vision with multifocal contact lenses in myopes and presbyopes

By paulgifford | August 11, 2020 | 0 Comments

This research showed that centre near design multifocal CL’s do not appear to reduce visual acuity at near in young accommodating myopes, but result in a slight reduction in visual acuity at distance.

Effect of high add orthokeratology lens designs on corneal hysteresis and ocular aberrations

By paulgifford | August 11, 2020 | 0 Comments

This research investigated orthokeratology lenses designed for a higher peripheral ‘add’ power, and how these influenced corneal hysteresis (rigidity) and higher order aberrations.
