Efeito do epitélio na absorção corneana de raios ultravioleta-A e riboflavina [PDF]

, 2011
PURPOSE: To determine if the corneal epithelium prevents the collagen cross-linking effect. Using immunofluorescence microscopy after CXL, we indirectly analyzed the role of the epithelium as ultraviolet-A (UVA) shield as well as a barrier to riboflavin ...

Clinical Outcomes of Repeated Corneal Crosslinking for Progressive Keratoconus After Failure of Primary Procedure; Safety and Efficacy at 12-Month Follow-Up

Ophthalmology and Therapy
Introduction This study aims to evaluate the efficacy and safety of repeated corneal cross-linking (CXL) in patients with progressive keratoconus who have undergone an unsuccessful primary epithelium-off (epi-off) CXL procedure. Additionally, it compares

Cell Adhesion by Design: Engineering Tissue Culture Scaffolds With Adhesion Cues

Advanced Materials Interfaces, EarlyView.
ABSTRACT In scaffold‐based tissue engineering, the matrix should provide adequate adhesion cues for cell attachment, spreading, and function. Given the multitude of adhesion receptors and the diversity of scaffolds, there are many approaches to render scaffolds adhesive, even though they are not all equivalent.

Structural corneal changes identified with the use of confocal microscopy after accelerated CXL for keratoconus

Journal of Ophthalmology, 2020
Background: Post-crosslinking (CXL) biomicroscopic changes in patients with keratoconus can be detected by confocal microscopy. Few studies reported on morphological changes in the cornea after CXL.
