In this review we explore the 6-year results for MiSight 1 day recently presented at the 2020 American Academy of Optometry meeting. Based on the abstract, children who were older at initial fitting (11-15 years) progressed similarly over 3 years to matched children who were treated for 6 years, indicating that older children could still gain a treatment effect from MiSight 1 day.
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.
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.
This research investigated orthokeratology lenses designed for a higher peripheral ‘add’ power, and how these influenced corneal hysteresis (rigidity) and higher order aberrations.
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.
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.
This study showed that adult high myopes with myopic macular degeneration (MMD) show reduced macular sensitivity as measured by microperimetry. That’s not unexpected; but the microperimetry changes occurred before BCVA changes in mild MMD – read more here.
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.
