Accommodation is unrelated to myopia progression in Chinese myopic children

By paulgifford | September 22, 2020 | 0 Comments

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.

The effect of orthokeratology on ocular aberrations

By paulgifford | August 11, 2020 | 0 Comments

Understanding how orthokeratology alters ocular aberrations helps to understand research and potential mechanisms of myopia control. Here we explain more.

Understanding spherical aberration

By paulgifford | August 11, 2020 | 0 Comments

Understanding spherical aberration is important in view of mechanisms of myopia development, progression and control. This blog explains positive and negative spherical aberration, how they relate to contact lens corrections and more.
