Journal of Ophthalmology, Volume 2026, Issue 1, 2026.Purpose To compare the accuracy of different formulas for calculating toric intraocular lens (IOL) power. Methods PubMed, EBSCO, Web of Science, and the Cochrane Library were systematically searched for studies published from 2015 to 2025. Numbers of eyes with a prediction error (PE) within ±0.50 and ±1.00 diopters (D) were synthesized for the meta ...

The effects of a HEV‐filtering contact lens on the brightness of natural images
Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1801-1810, November 2025.Abstract Purpose Yellow filters, including high‐energy‐visible (HEV) filtering lenses, have been thought to increase the subjective brightness of real‐world scenes, but laboratory results are mixed. This study used a brightness matching technique modified to present natural images using a broad spectrum of wavelengths: a visibly clear control contact ...

Deciphering the performance of different surface models for corneal topography
Ophthalmic and Physiological Optics, Volume 45, Issue 6, Page 1270-1281, September 2025.Abstract Purpose To study the performance of different corneal surface models to be used for ray tracing. Models based on geometric surfaces and polynomial fits were compared and the differences discussed. Methods For this simulation study, five characteristic generic surface configurations were generated: (A) perfect biconic, (B) decentred biconic ...

Presbyopia Correction in Lens Replacement Surgery: A Review
Clinical &Experimental Ophthalmology, Volume 53, Issue 6, Page 668-681, August 2025.ABSTRACT Presbyopia affects approximately 1.8 billion individuals globally, posing significant challenges as life expectancy and near‐vision demands, particularly with mobile phone use, grow. Addressing presbyopia during lens replacement surgery has become a key focus for cataract surgeons, aiming to reduce dependence on corrective eyewear. This review

Optometry and Vision Science, Volume 102, Issue 6, Page 387-393, June 2025.SIGNIFICANCE: Toric orthokeratology lenses show potential in slowing myopia progression in adolescents with moderate to high astigmatic myopia. These findings support the broader application of toric orthokeratology in managing challenging refractive conditions and mitigating myopia‐related complications. PURPOSE: This study seeks to probe the efficacy
