Abstract
An ophthalmic surgical device includes a housing having a distal end and a proximal end. A cannula is attached to the housing distal end and has a distal tip with at least one port in communication with a lumen extending through the cannula and in communication with an aspiration path in the housing. A vibration source is held within the housing for vibrating the distal tip of the cannula for assisting in vitreous and other tissue removal from a patient's eye. The vibration source creates a peak velocity of the distal tip equal to or less than a potential maximum flow velocity of water through the at least one port for a pressure differential between an intraocular pressure of the eye and a pressure within the cannula lumen that is less than the intraocular pressure.
