Stromal Transplantation and corneal-sparing techniques in ectatic diseases

open access: yesProgress in Retinal and Eye Research
Corneal ectatic and degenerative disorders have traditionally been managed with tissue-replacement strategies such as penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK). However, an improved understanding of corneal biomechanics, stromal wound healing, and immune privilege has driven a paradigm shift toward tissue-sparing and ...

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

open access: yesAdvanced 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 ...
