Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, Volume 104, Issue 5, Page 498-509, August 2026.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

N, S Co‐Doped Carbon Quantum Dots‐Riboflavin Composite Photosensitizers for Enhanced Iontophoresis‐Assisted Corneal Cross‐Linking

Advanced Science, Volume 13, Issue 42, 28 July 2026.
This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.

“Reactions in Leprosy: Updated Insights Into Pathophysiology, Clinical Spectrum, and Therapeutic Approaches—A Narrative Review”

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Reaction in leprosy is an immune‐mediated acute inflammatory episodes that occur in the natural course of Hansen's disease. Reaction can occur before, during, or after starting multidrug therapy and is a major cause of nerve damage, morbidity, and disability in affected individuals.

Awareness About Keratoconus and Its Relation With Eye Rubbing: A Cross‐Sectional Study in Riyadh

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background Keratoconus is a progressive eye disease affecting the cornea, the clear dome‐ shaped structure at the front of the eye. In keratoconus, the cornea thins and bulges outward into a cone shape, leading to loss of visual acuity. The aetiology of keratoconus remains unclear, but it involves both genetic and environmental factors.

Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

Advanced Functional Materials, Volume 36, Issue 22, 16 March 2026.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...
