The present disclosure generally relates to automated method and system for vision assessment of a subject. The method comprises: determining a set of test patterns for the subject based on a preliminary assessment of an eye of the subject; displaying the set of test patterns sequentially to the subject; collecting data on the subject's gaze in response to each test pattern displayed to the subject; and assessing vision functionality of the subject based on the collected gaze data.

Vision assessment based on gaze

A tubular piezoelectric transducer comprising a tube of piezoelectric material and having a plurality of external electrodes for inducing in a first end of the tube at least one movement of a plurality of possible movements; at least two spokes attached to and extending radially inwardly of the tube for movement with the first end; a hub at an inner end of the at least two spokes and being located on the longitudinal axis of the tube, the hub being attached to the at least two spokes for movement therewith; the hub being for receiving therein a probe for movement of the probe with the hub. A phaco-probe incorporating the transducer is also disclosed.
