Candida infection of a Boston Type I Keratoprosthesis (KPro)

Candida infection of a Boston Type I Keratoprosthesis (KPro)

Category(ies): Cornea, External Disease
Contributor: Jesse Vislisel, MD

The Boston Type I Keratoprosthesis is a prosthetic corneal replacement used to restore vision in individuals with severe corneal disease and contraindications to traditional keratoplasty techniques. Like other artificial implants in the body, the KPro may be a nidus for infection. Fungal infections may occur around the device stem and appear milky-white, as seen in these photographs. Also shown is a photograph prior to the infection for comparison (figure 1).
