In various embodiments, a cannula device includes an irrigation handpiece portion (with a first aspiration tip for aspiration and an irrigation fluid outlet for irrigation) and an aspiration handpiece portion (configured to aspirate fluid into a second aspiration tip that extends from a distal end of the aspiration handpiece portion). The cannula device is transformable between: (a) a coaxial mode in which the aspiration handpiece portion is coupled to the irrigation handpiece portion such that fluid is aspirated through the first aspiration tip and then the second aspiration tip in series and irrigation fluid is provided through the irrigation fluid outlet, and (b) a bimanual mode in which the aspiration handpiece portion is separated from the irrigation handpiece portion to provide aspiration through the second aspiration tip while the irrigation handpiece portion continues to provide irrigation fluid through the irrigation fluid outlet.
