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 ...

Comparison of Rebound and Applanation Tonometry in Eyes With Focal Corneal Edema
Veterinary Ophthalmology, Volume 29, Issue 2, March 2026.ABSTRACT Objective To determine the effect of corneal edema on intraocular pressure (IOP) readings and their accuracy and precision when obtained with handheld rebound and applanation tonometers. Animals and Procedures IOP readings from areas of focal corneal edema were compared to those from clear cornea in 10 eyes of 7 glaucomatous cats in vivo using
