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.
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.
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.
了解orthokeratology alters ocular aberrations helps to understand research and potential mechanisms of myopia control. Here we explain more.
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.
This study showed that multifocal contact lens wear in young adult myopes increases accomodative lag, and utilized auditory biofeedback training to improve it. The results and implications are discussed here.
Welcome to Part 2 of the updates from the American Academy of Optometry 2019 Meeting. These updates all sprung from Mark Bullimore and Noel Brennan’s fantastic session entitled Twelve Evidence Based Things That We Should Know About Myopia.
