Dual focus contact lenses and near viewing

This study examines the effect that dual focus contact lenses have on accommodation and defocus during near viewing, and the results provide clues towards understanding the myopia control mechanism of these contact lenses.

Atropine 0.01% combined with orthokeratology over two years

Atropine 0.01% combined with orthokeratology slows axial elongation to less than 0.1mm/year over two years in Chinese children aged 6-11 years. This is the equal-longest study on this topic and first to measure potential mechanisms of pupil size and choroidal thickness. The largest effect of the combination occurred in the first 6 months.

How do lighting levels and contrast affect vision with multifocal contact lenses?

In young adult myopes, Biofinity centre-distance +2.50 Add and NaturalVue multifocal contact lenses both showed reduced visual acuity in lower lighting and low contrast conditions, and especially with a glare source, compared to single vision. Reading rate under normal lighting was also reduced by 4-8%. The multifocal designs performed similarly, although Biofinity required more over-refraction for best distance acuity.

Managing a child with very high myopia

In this complex case of an 8-year-old child with very high myopia, management is discussed in view of specific recommendations from the International Myopia Institute Pathologic Myopia, Clinical Management Guidelines and Prevention of Myopia and its Progression Reports.

IMI Report on Prevention of myopia and its progression

In myopic children, interventions to slow progression are warranted to prevent the development of high myopia and subsequent pathology and also to reduce the economic burden caused by uncorrected and pathologic myopia. This IMI Report describes the latest advice on preventing the development and progression of myopia – read the summary here.

Clinical Leader Case Study: Managing myopia with the family

This case is highlights that myopia management decision making includes much more than a child’s refraction. Learn how Keyur Patel involved the parent in the conversation and decision making, to determine the starting myopia management option for now, as well as considering the future.

Clinical Leader Case Study: First myopia correction

Parents can be conservative about childhood contact lens wear, especially if they have no experience of myopia themselves. Read how Bhavin Shah successfully guided parents into embracing MiSight 1 day for their eight-year-old daughter, as her first myopia management strategy.

How do myopia control contact lenses impact binocular vision?

This study showed that aspheric multifocal soft contact lenses (Biofinity +2.50D and NaturalVue) reduce accommodative response and increase exophoria, while MiSight concentric dual-focus minimally impacts binocular vision function compared to single vision contact lenses. All myopia control contact lenses increased divergence range slightly but did not impact convergence.
