Compensation for axial elongation during multifocal soft contact lens wear: Results from the BLINK study

Optometry and Vision Science, Volume 103, Issue 3, March 2026.
ABSTRACT Purpose To determine the effect of +2.50 D add multifocal soft contact lenses (MFSCLs) compared to +1.50 D add and single vision contact lenses (SVCLs) on the relationship between axial elongation and myopia progression. Methods Individual estimates of D/mm were derived from the CLEERE Study, then applied to data from 289 participants in the ...

Driving Innovation: The Impact of National Health Policies on Optometry Research in East Asia

The International Journal of Health Planning and Management, Volume 41, Issue 1, Page 37-46, January 2026.
ABSTRACT This study examines the optometric research landscape in three East Asian countries—China, Japan, and Korea—analysing how research trends align with each country's national health strategies. By evaluating published articles and reviews from national journals between 2006 March 2025, we identify key areas of focus, including paediatric ...

Compensated versus uncompensated millimeters during myopia progression: Estimating H′ in children

Optometry and Vision Science, Volume 103, Issue 1, January 2026.
ABSTRACT Purpose The second principal point (H′) of the eye can be used to estimate the diopters of change in refractive error that result from each millimeter of axial elongation. Calculating the location of H′ requires data from phakometry, a technique not included in most myopia control clinical trials.

Clinical evaluation of the service life of orthokeratology lenses

Modern technologies in ophtalmology
A total of 315 people (623 eyes) wearing orthokeratology lenses (OKLs) were examined. The condition of the eyes and OCLs was assessed dynamically. Critical levels of deposits on the OCLs were observed after 12 months in 35.0% of eyes, and scratches in 39.3%.
