The prevalence of myopia in children is increasing worldwide and is viewed as a major
public health concern. This increase has driven interest in research into myopia prevention …

Overnight orthokeratology lenses are approved in countries all over the world for the
temporary reduction in myopia, and recently, one lens design has received regulatory …

Purpose To describe peripheral defocus when myopic eyes are corrected with spherical and
center-distance multifocal soft contact lenses while looking at distance and near. Methods …

Background To characterize the axial and off-axis refraction across four meridians of the
retina in myopic eyes before and after Orthokeratology (OK) and LASIK surgery. Methods …

Purpose: The purpose of this study was to evaluate the effect of orthokeratology for different
degrees of myopia correction in the relative location of tangential (FT) and sagittal (FS) …

Purpose: Higher myopic refractive errors are associated with serious ocular complications
that can put visual function at risk. There is respective interest in slowing and if possible …

PURPOSE The aim of this study was to examine the accommodation behavior of young
adult eyes wearing MFCLs and the effectiveness of these MFCLs at removing foveal …

Purpose To compare the peripheral refraction and spherical aberration profiles along three
visual field meridians of 16 commercial single vision (SV), bifocal (BF) and multifocal (MF) …

Objectives To assess the visual performance of multifocal contact lenses (MFCLs) with high
addition powers designed for myopia control. Methods Twenty-four non-presbyopic adults …

Purpose: To evaluate changes in the peripheral refraction (PR), visual quality, and
accommodative lag with a novel soft radial refractive gradient (SRRG) experimental contact …
