Abstract
A transparent illuminated infusion cannula is provided for illuminating an area during eye surgery. An optical fiber may be spaced a certain distance away from the cannula such that fluid flow around the distal end of the fiber and into the transparent cannula may occur with a much higher flow rate than what had previously been possible. The fiber cannula airspace may be optimized so that the cross-sectional area of the fluid conduit remains substantially constant in order to achieve a best compromise between high light transmittance and high fluid flow rate.
