Optical characterisation and vision quality assessment of two myopia control contact lenses

Ophthalmic and Physiological Optics, Volume 45, Issue 5, Page 1142-1150, July 2025.
Abstract Purpose This investigation examined the image and vision quality of two commercially available daily disposable myopia control soft contact lenses. Methods Wavefront errors were measured with an SHS Ophthalmic aberrometer for two myopia control soft contact lenses: a coaxially designed dual‐focus lens (omafilcon A, CooperVision MiSight® 1 day,

Effect of 0.025% atropine on ocular biometry changes during accommodation

Ophthalmic and Physiological Optics, Volume 45, Issue 3, Page 865-876, May 2025.
Abstract Purpose Low concentration atropine is an effective treatment to slow myopia progression and axial elongation and also reduces accommodation. On‐axis ocular dimensions of the eye change during accommodation; hence, this study aimed to quantify the effect of 0.025% atropine eye drops on accommodation‐induced changes in ocular biometry.

A metric‐based image‐formation model explains the improvement in subjective refraction using temporal defocus waves

Optometry and Vision Science, Volume 102, Issue 4, Page 196-203, April 2025.
SIGNIFICANCE Direct subjective refraction (DSR) is a novel method for refractive error measurements that uses temporal changes in defocus and a flicker minimization task. The computational models developed here are a framework for improving this clinical method.

Holographic Shack–Hartmann wavefront sensor based on the correlation peak displacement detection method for wavefront sensing with large dynamic range

, 2015
A method to expand the dynamic range for a Shack–Hartmann wavefront sensor (SHWFS) is proposed. An SHWFS consists of a microlens array and an image sensor, and it has been widely used to measure the wavefront aberration of a lightwave in various fields ...

Correction of wavefront rotation between interferometer and shack-hartmann sensor using bending modes

Journal of the European Optical Society-Rapid Publications, 2020
In some active optics system, the influence function, which is the surface deformation ability of an actuator, is measured by directly detecting the mirror surface using an interferometer and the surface correction of the primary mirror is done using the
