Abstract: The present invention relates to methods for determining the uniformity of the piezoelectric effect throughout a piezoelectric material using the time-of-flight of an acoustic wave through the material as a gauge of that uniformity.

Abstract: An irrigation/aspiration tip having a relatively rigid cannula attached to a hub and an open end opposite the hub. Coaxially and removable received over the tip is a soft elastomeric or rubber sleeve. The sleeve forms a gap between the sleeve and the cannula, the gap allowing irrigation flow. The distal end of the sleeve is closed by a cap of reduced diameter. The reduced diameter of the cap seals the distal end of the cannula. The relatively soft cap reduces the likelihood that the posterior capsule will tear during cortical clean-up and capsule polishing. Removing the sleeve allows the cannula to be resterilized an unlimited number of times, thereby allowing unlimited reuse of the cannula.
