Abstract: A system (200) for conducting a vision assessment test of an eye of a patient comprising: a display screen (201) for displaying at least one test profile to the patient; an eye tracker controlled for detecting a gaze direction data of the eye of the patient when viewing the test profile(s); and a processor for processing the detected gaze direction data and identifying a correlation between the gaze direction data and the test profile(s) to thereby obtain a vision assessment of the patients eye; wherein the system comprises a user interface (203) for enabling an operator of the system to author the test profile(s) for the patient by controlling one or more parameters of the test profile(s) prior to the vision assessment test being conducted.

Abstract: 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.

Abstract: The present invention relates to a system for displaying a video image to a user having a visual impairment. The system comprises a video camera, a data storage device, a processor and an image display device for displaying processed images in a display region. The processor is operative to perform at least one of the operations of (i) including in the display region, a marker at a location offset from a centre of the display region, whereby if the user, who suffers from blurred vision at the centre of the user's visual field, looks at the marker, the user sees the captured image in focus; or (ii) deforming a portion of the captured image by a correction matrix, whereby, upon displaying the processed images by the display device, the correction matrix corrects a deformation in a corresponding portion of the visual field of the user due to the visual impairment.

Abstract: 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.
