Automatic control of phacoemulsification needle trajectory

A system and method that includes inserting a needle of a phacoemulsification handpiece into an eye of a patient and vibrating the needle in a first trajectory. Matter from the eye is aspirated via an aspiration line while the needle is vibrated in the first trajectory. An indication is received, of a vacuum level in the aspiration line. Determined is, that the vacuum level has changed by at least a preset vacuum level change, and in response vibrating the needle is switched to a second trajectory, different from the first trajectory.

Managing phacoemulsification user defined protocols

An eye surgery system includes an Input/Output (I/O) device and a processor. The I/O device is configured to enable a user to define one or more eye surgery protocols, and further configured to, using the I/O device, present a graphical user interface (GUI) that displays one or more user defined eye surgery protocols. The processor is configured to (a) present the one or more user defined eye surgery protocols on the I/O device using the GUI, (b) test compatibility of the one or more user defined eye surgery protocols with the eye surgery system, and (c) provide an indication of the compatibility to a user of the eye surgery system.

Surgical cleaning device

A surgical cleaning device and method of use having a housing, a drive shaft rotatably mounted, having a rear end and a front end, a brush head positioned at the front end and arranged outside the housing, to which a plurality of elastically deformable bristles are attached, a pump connected with the drive shaft for pumping a rinsing liquid, a gearbox that is connected with the front end of the drive shaft and with a rear end of the tube and which translates the rotational movement of the drive shaft into an oscillating linear movement of the tube and the brush head, wherein the tube is mounted movable in a linear manner; the brush head in the region of the elastically deformable bristles has at least one ejection opening, wherein the tube opens liquid-permeably through the at least one ejection opening in the direction of the elastically deformable bristles.

Phacoemulsification irrigation apparatus with load cell and optical sensor

A system includes an enclosure, an irrigation retainer, one or more sensors, and a processor. The irrigation retainer is coupled with the enclosure and configured to accept an irrigation container holding irrigation fluid for pumping to a phacoemulsification handpiece. The one or more sensors are coupled with the irrigation retainer and configured to provide at least one signal indicative of a remaining amount of the irrigation fluid. The processor is configured to receive the at least one signal, and in response to the at least one signal, output an estimation of the remaining amount of the irrigation fluid in the irrigation container or an estimation of the amount of irrigation fluid used.
