Improved centration of the type 1 boston keratoprosthesis in donor carrier tissue

Abstract

The type 1 Boston Keratoprosthesis preparation requires a 3-mm central punch and an 8.5 mm or larger punch in the carrier tissue. These punches are ideally concentric, but we have found difficulty in achieving concentric punches when the larger punch is performed first. We present a modification in the preparation procedure to help minimize centration error. © 2010 Khalifa and Moshirfar.
