Title: High frequency ultrasonic process and apparatus for selectively dissolving and removing unwanted solid and semi-solid materials and the like

Abstract: The present disclosure deals with ultrasonically selectively dissolving solid and semi-solid unwanted materials, such as vitreous gels, membranes, cataracts and similar materials in ophthalmic operation applications, for example, by radiating from a physically small source, high-frequency, preferably pulsed, acoustic waves, while positioning the material to be selectively locally dissolved by such waves at a selected region sometimes in contact with or near-contact or within a short distance from the source of the order of a millimeter or so, at which the propagated acoustic wave energy can effect such phenomena as, for example, localized cytolysis of the material at the selected region thereof substantially normal to the wavefront of the radiated acoustic wave region, and without substantial damage to the portions of the material external to said selected region, and with adjustment to obviate any substantial temperature rise at the material.
