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.

Abstract: A gemstone arrangement is described including a primary gem and at least one complementary gem. The primary gem includes a crown and a pavilion. The pavilion has an external wall defining an outer surface. The complementary gem has a crown defining a table. The table is in juxtaposition to and aligned with the pavilion wall for the maximum passage of ambient light from the complementary gem into the primary gem to enhance its visual appearance. In addition, the complementary gem has the same, but more intense color as the primary gem to intensify the color of the primary gem so a weak colored primary gem can appear intensely colored.

In addition, the complementary gem can be positioned and aligned to receive light losses from the primary gem and return those light losses through the crown of the complementary gem to the primary gem.
