Abstract
An apparatus for ultrasound scanning of the eye is provided comprising a virtual center translocation mechanism that facilitates precise arcuate motion of an ultrasonic transducer to maintain focal distance from the eye and to maintain normality of the ultrasound beam with surfaces of the eye. The invention also provides a radius adjust mechanism for changing the radius of ultrasound scanning to facilitate positioning of the transducer focal point on selected surfaces of the eye. Centration optics are also provided, for aligning the ultrasound transducer with the Purkinje (or other optical or geometric) axis of a patient's eye. In addition the invention provides a hygiene barrier eyeseal for protection of the patient from disease propagation.
