How we can identify future myopes

The axial length growth trajectories modelled in this study revealed that regardless of a child’s age, a myopic shift of at least -0.85D and/or 0.74mm over three years suggests future myopia development. Read more about specific risk factors for younger children, and other ocular component findings in this large study of European children.

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.

Myopia control and no rebound with Highly Aspherical Lenslet spectacles

This cross-over study investigated children wearing highly aspherical lenslet (HAL) spectacle lenses versus single vision spectacles over three six-month periods. The HAL lenses showed consistent myopia control efficacy and no rebound effect when discontinued over one of the six-month periods.

Dry eye and myopia in teenagers

This abstract reported on the association between myopia and dry eye disease in teenagers. Interestingly, dry eye disease and reduced break up time was associated with higher myopia, but photophobia and pain were not.

Evaluating the impact of pandemic lifestyle changes for Dutch teens

Teenagers in the Netherlands were able to spend time outdoors during the COVID pandemic but still significantly increased near work on digital devices.. This is expected to give an increase in myopia prevalence and progression in European teens but to a lesser extent than in Asia where there was restricted outdoor time with stricter lockdown.

What is the effect of low-dose atropine on binocular vision?

Low-dose atropine (0.05% or less) has a maximum effect on pupil size for both bright and dim light conditions within an hour of instillation, but has little to no effect on binocular vision in myopic children when used for myopia management.

Is axial length growth significantly different in children based on ethnicity?

This is the first meta-analysis to directly compare mean axial growth across studies, looking at how age and ethnicity contribute to differences. Current axial length growth charts differentiate by sex and ethnicity, with age being the key variable. The results indicate that mean annual axial length growth is 28% greater in Asian compared to non-Asian children., reaffirming the need for Asian-specific data.

The importance of myopia control soft contact lens design

Increasing power in a myopia control treatment zone of a multifocal soft contact lens can increase myopia control efficacy but negatively impact vision. This study is the first optical characterization of a novel design to improve this relationship between treatment zone power and vision quality.
