Patients with a keratoprosthesis often develop complications including glaucoma, requiring glaucoma drainage devices. In most of these patients, glaucoma drainage devices have been shown to be safe and effective. However, occasionally, a glaucoma drainage device in the setting of a keratoprosthesis can lead to conjunctival erosion with mechanical trauma. While repeat surgical intervention may appear necessary, we report a case of a patient who had improved conjunctival erosion and glaucoma drainage device exposure after refitting of a therapeutic contact lens. Therapeutic contact lenses can be used to maintain hydration and decrease exposure while improving cosmesis and refractive error. Complications following keratoprosthesis surgery are an understudied area, particularly regarding glaucoma drainage devices, and we seek to show that careful fitting of therapeutic contact lenses may avoid the risks of repeat surgical intervention.
