Corneal collagen cross-linking (CXL) is the only conservative treatment currently available to halt keratoconus progression by improving the biomechanical rigidity of the corneal stroma. The aim of this manuscript is to highlight the methods of three different protocols of CXL: conventional CXL (C-CXL), accelerated CXL (A-CXL), and iontophoresis CXL (I-CXL).

Endothelial corneal transplantation is a surgical technique for treatment of posterior corneal diseases. Mechanical microkeratome dissection to prepare tissue results in thinner, more symmetric grafts with less endothelial cell loss and improved outcomes. Dissections can be performed at the eye bank prior to corneal transplantation surgery.

This video demonstrates a non-invasive laser-assisted procedure to selectively damage the corneal endothelial cells in the porcine eye. The developed ex vivo model of endothelial cell damage can be used to study diseases of the corneal endothelium.
FAQs
The key electrical source is ionic transport across the corneal epithelium. These fluxes create extracellular currents and voltage gradients, while epithelial barrier function influences how those signals appear at the surface. Mapping these linked electrical features helps researchers connect transport behavior with tissue state rather than treating the measured signal as an isolated voltage value.
Spatial resolution shows how electrical activity varies across different corneal locations. A localized measurement could miss regional differences associated with epithelial condition, injury, or healing. By comparing signals across multiple positions, researchers can relate the distribution of currents to tissue behavior and identify changes that would be difficult to interpret from a single measurement.
Injury can change epithelial organization and cellular activity, which may modify the local currents and voltage gradients generated at the surface. Corneal current mapping therefore provides a way to follow wound-related bioelectric signals during healing. The resulting spatial patterns can help connect electrical changes with repair processes without relying only on structural observations.
A measurement begins by positioning sensitive microelectrodes or related probes at the corneal surface. Signals are collected from multiple locations so that local currents and voltage gradients can be compared. The measurements are then organized into a spatial map, allowing researchers to examine regional electrical behavior and relate it to epithelial function or injury-related changes.
The map can reveal the distribution of extracellular currents and voltage gradients across the tissue. Researchers can use these patterns to characterize epithelial barrier function, examine wound-related bioelectric signals, and assess changes in cellular activity during healing. Its value comes from combining electrical measurements with spatial context, making regional differences part of the interpretation.
In physics, the method links ion transport, extracellular electrical fields, and tissue behavior within a living biological surface. In biomedical research, those measurements support studies of ocular disease, repair mechanisms, and therapeutic strategies. Corneal current mapping thus provides a shared framework for examining how electrical states change when the epithelium is intact, injured, or recovering.
