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.
Myopia has multi-factorial causes with both nature and nurture contributing. In this research the authors used a retrospective cohort study to examine any differences in progression rate with different ethnicities and greater understand who may be at increased risk of myopic progression.
In myopia development the sclera is at risk of deformation due to increasing axial length progression. This research investigates whether cross-linking treatment could be used to stiffen the sclera as a way to restrict axial eye elongation.
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.
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.
This research investigated orthokeratology lenses designed for a higher peripheral ‘add’ power, and how these influenced corneal hysteresis (rigidity) and higher order aberrations.
Understanding how orthokeratology alters ocular aberrations helps to understand research and potential mechanisms of myopia control. Here we explain more.
Spherical aberration is employed to create centre distance and centre near multifocal contact lenses. This blog explains how SA relates to myopia and accommodation, and puts this in view of MFCL research for myopia control.
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 are important in view of mechanisms of myopia development, progression and control. This blog helps clarify this concept to help you understand research.
