CONTACT LENS MODIFICATIONS FOR BOSTON KERATOPROSTHESIS

Abstract

Boston Keratoprosthesis Type 1 (KPro), an artificial cornea, is a therapeutic option for patients in need of corneal transplantation when the prognosis of traditional keratoplasty is guarded. Bandage contact lens wear is essential in the post-operative management of KPro eyes in order to maintain adequate corneal graft hydration, and minimize the risk of adverse complications. Suitable bandage contact lens selection is imperative to preserve keratoprosthesis function, and customized modifications of contact lens parameters may be necessary to ensure adequate fitting. The available contact lens options, modifications, and protocols for the continued care of Boston Keratoprosthesis are discussed. A simple, yet unreported modification for contact lenses fit over KPro eyes in the setting of ocular surface irregularities is proposed, which may hold clinical utility when fitting keratoprosthesis patients with scleral elevations and glaucoma filtrationdevices.
