The QuickSee autorefractor reliably measures the accommodative response in children compared with the Shin‐Nippon autorefractor

open access: yesOphthalmic and Physiological Optics, EarlyView.
Abstract Introduction This study evaluated the QuickSee autorefractor for measurement of the accommodative response in a cohort of children without significant ametropia, and compared the findings to those determined using the gold‐standard Shin‐Nippon device. Methods Children aged 5–7 years were recruited.

Ocular surface characteristics and its association with soft contact lens fitting

open access: yesOphthalmic and Physiological Optics, EarlyView.
Abstract Purpose To analyse the associations between ocular surface shape parameters and soft contact lens fitting. Methods A total of 106 eyes of 53 participants (53 right and 53 left eyes) fitted with standard silicone hydrogel soft lenses were analysed retrospectively.

Myopia control with a novel peripheral gradient soft lens and orthokeratology: a 2-year clinical trial [PDF]

open access: yes, 2015
Objective. To evaluate the degree of axial elongation with soft radial refractive gradient (SRRG) contact lenses, orthokeratology (OK), and single vision (SV) spectacle lenses (control) during a period of 1 year before treatment and 2 years after ...

Accuracy and precision of a sphero‐cylindrical over‐refraction app for smartphones

open access: yesOphthalmic and Physiological Optics, EarlyView.
Abstract Purpose To evaluate the accuracy and precision of a web‐based smartphone app designed to measure sphero‐cylindrical over‐refraction. Methods A total of 307 healthy young subjects (22.5 ± 3.4 years) underwent clinical subjective refraction. In addition to each subject's refractive correction, spherical and cylindrical errors from −1.50 to 0.00 ...

Factors predicting myopia incidence in China and Europe

open access: yesOphthalmic and Physiological Optics, EarlyView.
Abstract Aims To develop a predictive model for myopia incidence using population‐based data from Chinese and European children. Methods Analysis of four longitudinal studies from the UK, Sweden and China was conducted. Data from 4405 non‐myopic children aged 6 to 16.8 years with spherical equivalent (SE) refraction from −0.49 D to +10.00 D were ...

Receding and disparity cues aid relaxation of accommodation [PDF]

open access: yes, 2009
Purpose. Accommodation can mask hyperopia and reduce the accuracy of non-cycloplegic refraction. It is, therefore, important to minimize accommodation to obtain a measure of hyperopia as accurate as possible.
