An irrigation and aspiration apparatus suited for irrigation and aspiration during an eye surgery procedure includes a hollow aspiration cannula having proximal and distal ends. An outer, aspiration tip is positioned on at least the distal end of the aspiration cannula, and includes a generally spherical body portion defining an aspiration port in fluid communication with an interior passage defined by the aspiration cannula. The aspiration cannula defines an annular retention step at an outer surface thereof spaced from the distal end, with the aspiration tip defining an internal, annular abutment surface for engagement with the annular retention step to maintain the aspiration tip on the cannula in substantially fluid-tight relationship therewith.
