Artificial corneas or keratoprostheses such as the Boston keratoprosthesis (KPro) are being used more frequently to provide a clear corneal window in patients with severe corneal disease. A significant percentage of patients who undergo Boston KPro implantation require subsequent eyelid surgery. However, few articles in peer-reviewed literature evaluate the indication and outcome of eyelid procedures after Boston KPro implantation. This study examines the frequency, nature, and outcomes of oculoplastic procedures in patients with Boston KPro implantation.


A retrospective chart review was conducted of all KPro-1 procedures performed at the University of Illinois at Chicago between December 2006 and September 2010 and all KPro-1 and KPro-2 procedures performed at the University of Iowa between December 2008 and October 2010.


One hundred and twenty eyes underwent Boston KPro-1 procedures, and 2 eyes underwent Boston KPro-2 procedures. Twenty-one (17.2%) of the 122 eyes required subsequent eyelid alterations. Chemical burn was the most common preoperative corneal diagnosis (8 of 21; 38.1%). A variety of oculoplastic procedures were performed; the most common procedure was a permanent lateral tarsorrhaphy. Seventeen (81.0%) of 21 KPro eyes that underwent oculoplastic procedures maintained the KPro at an average of 12.4 months of follow up.


A significant number of patients with Boston KPros require subsequent eyelid surgery. With limited existing literature and increasing popularity for using Boston KPros to treat severe corneal disease, it is essential for oculoplastic and corneal surgeons to understand the need for eyelid alterations in these patients and the surgical intricacies surrounding these cases.
