Abstract
A cannula support serves in supporting a cannula relative to a non-contact lens assembly and a positioning mechanism for positioning the non-contact lens assembly. The cannula support includes a cannula holder and a gripper disposed relative to the cannula holder. The cannula holder is provided for receiving at least a portion of the cannula. The gripper is adapted to cooperatively engage a portion of one of the non-contact lens assembly and the positioning mechanism.

A method of irrigating an eye during eye surgery, comprising:
- providing a cannula support and a cannula having a tip, the cannula support including a cannula holder adapted to receive at least a portion of the cannula, and a gripper disposed relative to the cannula holder, the gripper having at least one arm depending from the cannula holder;
- fixing the position of a portion of the cannula relative to the cannula support with the cannula holder;
- attaching the cannula support relative to a non-contact lens assembly and a positioning mechanism for positioning the non-contact lens assembly by holding a portion of one of the non-contact lens assembly and the positioning mechanism with the at least one arm;
- positioning the non-contact lens assembly and the cannula support relative to the eye with the positioning mechanism;
- positioning the tip of the cannula adjacent the eye;
- and
- actuating the cannula to provide a supply of fluid to the eye.
