Abstract: A device configured to guide creation of an incision in a sclera of an eye including an elongate handle and a footplate having a plurality of struts defining a central opening extending between an upper surface and a lower surface of the footplate. A first strut of the plurality of struts has a proximal-facing blade guide surface that is straight and extends between two lateral struts of the plurality of struts. A second strut of the plurality of struts has a proximal-facing limbal guide surface that is curved. The blade guide surface is separated a distance from the limbal guide surface to identify a target location for creating an incision relative to a limbus of the eye. The blade guide surface has a length between the two lateral struts that limits a length of the incision that can be created using a cutting blade inserted through the central opening.
