Abstract

To evaluate the surgical management of vitreoretinal pathology in patients with a permanent Boston Type 1 keratoprosthesis (hereafter referred to as a KPro) in the era of small-gauge vitrectomy techniques.Retrospective review of 23 small-gauge vitreoretinal surgical procedures during or after Dohlman-Doane KPro placement in 14 eyes.Established and innovative techniques were used, including sutureless small-gauge vitrectomy, temporal positioning of surgeon, long-term tamponades, and exploratory endoscopy. Retro-KPro membranes formed less frequently when vitrectomy was performed during KPro placement. Anatomical goals were achieved, and no serious complications directly resulted from these techniques. Visual acuity, frequently limited by preexisting pathology, improved in most cases.Modern posterior segment surgical techniques, including small-gauge sutureless vitrectomy, can be effectively used for patients with a permanent KPro. Vitrectomy and glaucoma tube revision by a team of subspecialists at the time of KPro placement may reduce subsequent complications.
