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

Ophthalmic 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.

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

Ophthalmic 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 ...

Myopia control and modulation transfer functions for multisegment spectacle lenses

Ophthalmic and Physiological Optics, EarlyView.
Abstract Introduction Multisegment (MS) spectacle lenses, providing a distance correction with a clear central area and by having an array of small, positively powered lenslets in the periphery of the front surface, have proved effective in slowing childhood myopia progression.

Deep learning–empowered low‐cost portable automated refraction system: A solution to the inadequate effective correction rate of refractive errors in resource‐limited areas

Ophthalmic and Physiological Optics, EarlyView.
Abstract Aims To develop and validate a low‐cost, portable automated refraction system (Tongren Digital Sight, TRDS) using deep learning and infrared eccentric photorefraction to improve refractive error correction in resource‐constrained settings. Methods This randomised controlled crossover trial enrolled 282 participants (18–60 years of age) at ...

Impact of contact lens correction on wavefront aberrations and vision quality in keratoconus

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose To review the optical principles of contact lens correction in keratoconus, with a focus on residual ocular wavefront error and its impact on vision performance. Findings Corneal rigid gas permeable (RGP) contact lenses, commonly used in keratoconus management, often fail to improve vision quality to levels observed in non‐diseased ...
