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.

Neovascularization (NV) of the cornea can complicate multiple visual pathologies. Utilizing a controlled, alkali-burn injury model, a quantifiable level of corneal NV can be produced for mechanistic study of corneal NV and evaluation of potential therapies for neovascular disorders.

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
Loose, damaged, or infected epithelial tissue can interfere with restoration of the ocular surface. Its careful removal leaves a cleaner corneal surface, allowing healthy epithelial cells to migrate across the defect and re-cover it. This process can improve surface integrity, although healing depends on appropriate technique and follow-up care.
The procedure addresses both compromised epithelial tissue and material adhering to the cornea. By separating tissue that is no longer functioning normally, it creates a more suitable surface for epithelial coverage. The intended outcome is not simply cleanliness, but progressive restoration of the corneal epithelium and improved ocular surface integrity.
Material removed during corneal debridement may be collected for diagnostic evaluation. This can help clinicians examine tissue or debris associated with a compromised corneal surface, particularly when infection or another cause of epithelial damage is being considered. Thus, the procedure can serve both a therapeutic purpose and a source of information about the ocular condition.
A clinician uses a sterile instrument or applicator to address the affected corneal surface. The nonviable, loose, damaged, or infected epithelium and associated debris are gently separated and removed. The resulting surface is then available for healthy epithelial cells to migrate across, with technique and subsequent care influencing the healing process.
Potential uses include recurrent corneal erosions, selected infectious or traumatic injuries, and other disorders in which the corneal epithelium has become compromised. The procedure is therefore condition-dependent rather than appropriate for every ocular-surface problem. Its role may include supporting epithelial recovery, improving surface integrity, or obtaining material for diagnostic assessment.
Careful technique and appropriate aftercare help limit problems associated with exposing a corneal epithelial defect. The overview identifies discomfort, infection, and delayed re-epithelialization as concerns that require attention. Managing these factors supports the intended outcome: healthy epithelial coverage and recovery of a more stable ocular surface.
