1. An apparatus for guiding a cannula through an incision in an eye, wherein the cannula has a generally rectangular or elliptical cross-section, the apparatus comprising:
(a) a body, the body having a top surface, an upper inner surface, and a pair of flat bottom surfaces; and
(b) a pair of rigid legs, wherein each rigid leg of the pair of rigid legs extends downwardly from a respective bottom surface of the pair of flat bottom surfaces such that each bottom surface faces toward a respective leg of the pair of rigid legs, wherein the rigid legs are parallel with each other, wherein each rigid leg has a sharp tip dimensioned for insertion through a surface of the eye, wherein the rigid legs both extend along a first plane;
wherein the body has a plurality of additional surfaces at least partially defining a guide opening with the upper inner surface, wherein a portion of the guide opening is positioned between the pair of flat bottom surfaces of the body and the upper inner surface of the body, wherein the guide opening is oriented transversely relative to the first plane, wherein the guide opening is sized to receive the cannula having the generally rectangular or elliptical cross-section such that the guide opening is configured to maintain the cannula in a substantially tangential orientation relative to the incision when the pair of rigid legs are inserted through the surface of the eye, wherein the guide opening is open along an entire bottom of the guide opening, adjacent to the pair of flat bottom surfaces of the body.
