Corneal melt around Boston type I keratoprosthesis

Contributor: Jesse Vislisel, MD

Boston keratoprosthesis devices require regular monitoring to assess for the presence of complications such as infection and corneal melt. Anterior segment optical coherence tomography (OCT) is a useful study to assess for the presence of corneal thinning or melt. We regularly use OCT to monitor the status of the cornea around the device.
