Surface epithelialization of the type i Boston keratoprosthesis front plate: Immunohistochemical and high-definition optical coherence tomography characterization
Prostheses and Implants
Tomography, Optical Coherence
The transparent tissue layer covering the anterior surface of the type I Boston keratoprosthesis front plate was found to represent non-keratinized squamous epithelium, most likely of corneal epithelial origin. This potentially represents a further step in bio-integration of the keratoprosthesis device. In particular, epithelial coverage of the critical junction between the device and the carrier corneal tissue might serve an important barrier function and further reduce the incidence of infection and extrusion of the type I Boston permanent keratoprosthesis.
