Abstract

The present disclosure relates to an infusion cannula for use in connection with vitreo-retinal surgical procedures. The infusions cannula comprises a hollow body portion defining a first direction for an infusate flow. The hollow body portion includes a proximal end and a distal end, which distal end includes a tapered distal tip integrally formed therewith. The infusion cannula further includes a pair of diametrically opposed delivery holes formed radially through the body portion near the tapered distal tip, wherein a first of the pair of delivery holes is oriented to direct the infusate flow in a second direction which is orthogonal to the first direction and wherein a second of the pair of delivery holes is oriented to direct the infusate flow in a third direction which is orthogonal to the first direction and parallel to the second direction. The first and second delivery holes dividing the infusate flow such that the infusate flow is equally divided in opposite directions and directed tangentially along the equator of a lens.
