Abstract: Frequency-domain signal processing of pressure sensor signals and/or flow signals is used to provide on-demand control of a multi-component fluidic system. An example method, implemented in a phacoemulsification system comprises receiving a signal from each of one or more sensors, the one or more sensors comprising at least one pressure sensor, and converting each of one or more of the received signals, including at least one signal from a pressure sensor, to a frequency-domain representation of the received signal. The method further comprises identifying, based on the frequency-domain representations of received signals, at least one event from a set of predetermined events, and controlling one or more fluid control devices, responsive to the identifying.

Abstract: An ultrasonic cutting tip has a hollow shaft with a proximal and distal end. The proximal end is configured to be attached to an ultrasonic hand piece, and the distal end has a smooth continuous surface. An opening is located near the distal end of the hollow shaft. The opening is configured to cut vitreous when the cutting tip is vibrated ultrasonically in a torsional manner.

Abstract: According to certain embodiments, a surgical cassette for an ophthalmic surgical system comprises an irrigation conduit that is in fluid communication with a handpiece and carries fluid toward a surgical site. An aspiration conduit is in fluid communication with the handpiece and carries fluid away from the surgical site. An aspiration pump creates a vacuum pressure in the aspiration conduit to draw fluid through the aspiration conduit towards a drain reservoir. A reservoir couples with a pressure-vacuum source to manage the reservoir pressure. A valve is in fluid communication with the aspiration conduit and the reservoir, and provides one or more channels between the aspiration conduit and the reservoir. Each sensor detects a pressure associated with the surgical site. A computer controls the valve in response to the pressure detected by the one or more pressure sensors to mitigate a pressure or volume change.

Abstract: Embodiments of the present disclosure provide a surgical instrument having a pressure sensor incorporated in, or adjacent to, a distal end of the surgical instrument to enable direct intraocular (IOP) readings of an eye. The surgical instrument may include a hand-held device that is inserted into the eye to perform a surgical task.
