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

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

Understanding spherical aberration

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.

Understanding Ocular Wavefront aberrations

Understanding ocular wavefront aberrations are important in view of mechanisms of myopia development, progression and control. This blog helps clarify this concept to help you understand research.

Influence of centre near design multifocal CLs on visual acuity in young myopes and presbyopes

By paulgifford | August 4, 2020 | 0 Comments

Centre near design multifocal CL’s do not appear to reduce visual acuity at near in young accommodating myopes, however the results from this study suggest slight reduction in visual acuity at distance.

Predicting future myopia progression from prior myopia progression

How well does prior progression predict progression for the next year? The results provide a simple clinical message while also indicating the complexity of this field.

Using growth charts to track progression of myopia – can they be used to predict success with MiSight?

By paulgifford | July 28, 2020 | 0 Comments

Can centile growth charts for axial length growth be used to predict success with a myopia control intervention? The three-year MiSight data was modelled against population data as a step towards validated normative data.
