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 ...

Immediate Postoperative Decentration of a Biologic Corneal Inlay Managed With Tomography‐Guided Repositioning: A Case Report

Clinical Case Reports, Volume 14, Issue 3, March 2026.
Immediate postoperative Pentacam corneal tomography revealing inferior‐temporal decentration of the biologic corneal inlay on the axial curvature map. ABSTRACT Biologic corneal inlays can rarely present with immediate postoperative decentration, which can be subtle and difficult to detect clinically. Real‐time tomography allows precise early diagnosis,

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

Acta 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 ...
