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 ...

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

Advanced Science, Volume 13, Issue 10, 18 February 2026.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

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

Journal 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 ...
