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,

Deconvolution Techniques in Optical Coherence Tomography: Advancements, Challenges, and Future Prospects

Laser &Photonics Reviews, Volume 19, Issue 12, June 18, 2025.
This review explores deconvolution techniques in optical coherence tomography (OCT), addressing resolution degradation from point‐spread functions (PSF). It reviews foundational principles (e.g., Richardson‐Lucy deconvolution) to advanced AI‐driven methods, emphasizing clinical translation and interdisciplinary collaboration. Real‐world implementations

Accurate measurement of Cn2 profile with Shack-Hartmann data

, 2012
The precise reconstruction of the turbulent volume is a key point in the development of new-generation Adaptive Optics systems. We propose a new Cn2 profilometry method named CO-SLIDAR (COupled Slope and scIntillation Detection And Ranging), that uses ...

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.
