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,

Electric Field Conjugation with the Project 1640 coronagraph

, 2013
The Project 1640 instrument on the 200-inch Hale telescope at Palomar Observatory is a coronagraphic instrument with an integral field spectrograph at the back end, designed to find young, self-luminous planets around nearby stars. To reach the necessary

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

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.
