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).

Porcine Ex vivo Cornea Model of Bacterial Keratitis: A Technique to Establish Bacterial Infection in Corneal Epithelial Cells
0 Views •
2025
This video describes a protocol to set up an ex vivo model for bacterial keratitis using a corneoscleral button dissected from the porcine eye. Inoculated bacteria traverse the corneal epithelial incisions to invade the underlying stroma and establish an infection within the corneal tissues that mimic the in vivo infection.
FAQs
Healing begins when remaining epithelial cells migrate across the defect, followed by cell proliferation that replenishes the lost layer. The speed and quality of this response influence restoration of the corneal surface and contribute to visual recovery. Because regeneration is central to the outcome, epithelial healing must be considered alongside the intended treatment or diagnostic purpose.
The epithelium can be removed to expose the stroma while limiting disruption to deeper structures. This balance is important because the exposed tissue provides access for reshaping or treatment, whereas avoidable deeper injury could complicate recovery. Controlled removal therefore supports the procedure’s objective while preserving the conditions needed for orderly epithelial repair.
The epithelial defect affects several clinically relevant outcomes, including pain, infection risk, wound healing, and visual recovery. These concerns arise because the protective surface has been interrupted before regeneration restores coverage. Monitoring the healing response is therefore important when evaluating the result of a procedure or managing a patient after treatment.
The procedure may use mechanical separation or gentle mechanical debridement to lift or remove the epithelial layer. The approach is intended to expose the underlying corneal tissue while minimizing injury to deeper structures. The selected technique must therefore provide adequate access for the planned purpose and leave a wound capable of subsequent migration and proliferation.
Clinicians use this step in procedures such as photorefractive surgery and in selected corneal therapies. Removing the surface layer can provide access needed for tissue reshaping or treatment delivery. Its value depends on matching controlled exposure with the clinical goal, followed by attention to epithelial regeneration and the factors that affect recovery.
By exposing the tissue beneath the epithelial layer, removal can support diagnostic work and research involving the cornea. It also provides a setting for studying how epithelial cells migrate and proliferate during repair. These uses connect the procedure with broader questions about tissue access, wound healing, and the recovery of the transparent corneal surface.
