Theoretical effect of changes in entrance pupil magnification on wavefront-guided laser refractive corneal surgery

open access: yes, 2005
Purpose: To explore theoretically the effect on the correction of higher order aberrations of changes in the magnification between the aperture stop (iris) and entrance pupil of the eye, following myopic excimer laser ablation.\ud Methods: Using a ...

A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

open access: yesActa Ophthalmologica, Volume 104, Issue 2, Page e122-e138, March 2026.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

Assessing Effects of Riboflavin/UV‐A Cross‐Linking on Aqueous Outflow Facility, Corneal Biomechanics and Their Association With Intraocular Pressure

open access: yesJournal of Biophotonics, Volume 19, Issue 2, February 2026.
Our study demonstrates that UV cross‐linking (CXL) reduces outflow facility while increasing corneal elasticity across IOP levels of 20–40 mmHg, measured using direct manometry and non‐contact optical coherence elastography. These results highlight both parameters as potential indicators for evaluating CXL effectiveness and monitoring keratoconus ...

Driving Innovation: The Impact of National Health Policies on Optometry Research in East Asia

open access: yesThe International Journal of Health Planning and Management, Volume 41, Issue 1, Page 37-46, January 2026.
ABSTRACT This study examines the optometric research landscape in three East Asian countries—China, Japan, and Korea—analysing how research trends align with each country's national health strategies. By evaluating published articles and reviews from national journals between 2006 March 2025, we identify key areas of focus, including paediatric ...

Retinal Peripheral Defocus and Peripheral Refractive Measurement Techniques: A Review

open access: yesJournal of Ophthalmology, Volume 2026, Issue 1, 2026.
The theory of retinal peripheral defocus currently represents the prevailing paradigm for myopia prevention and control. Research studies on peripheral refraction indicate that peripheral defocus is significantly associated with the management and progression of myopia.
