Diffuse lamellar keratitis after epi-off corneal crosslinking: An under-recognized complication?

American Journal of Ophthalmology Case Reports, 2019
Purpose: To report diffuse lamellar keratitis (DLK) occurring in an eye that underwent epithelium-off (epi-off) corneal cross-linking (CXL) as a treatment for post-surgical ectasia and the successful treatment of progressive ectasia with a novel epi-on ...

“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 ...

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,
