Abstract: Devices and methods are disclosed for improved followability in laser-based ocular procedures. In some embodiments, an ophthalmic instrument comprises a projection located at the distal end of the shaft or cannula, the projection having a distal surface in proximity to the distal end of the optical fiber, the distal surface adapted to be positioned facing the treatment area during use of the ophthalmic instrument. An example method includes delivering laser energy through an optical fiber to the treatment area, wherein the distal surface of the projection inhibits bubbles formed during the procedure from moving distally away from the distal end of the ophthalmic instrument.

Abstract: Systems and methods are disclosed for dynamically controlling laser pulses being output from a laser system. An example surgical system comprises a laser, an optical switching device, an adjustable input device such as a foot pedal, and a laser pulse controller. An operator actuates the adjustable input device over an operating range to control dynamically the laser pulses being output from the laser system. In one mode, the adjustable input device may dynamically control output laser energy. In another mode, the adjustable input device may dynamically control selection of laser pulses to be output from the system.

Abstract: Systems and methods are disclosed comprising an ultrasonic handpiece having a housing, a working tip extending from the distal end of the housing, and a crystal and horn assembly positioned within the housing. The proximal end of the ultrasonic horn is free to move relative to the housing. In embodiments, the ultrasonic horn is resiliently suspended within the housing, with no rigid fixation points. The ultrasonic horn may be resiliently suspended by one or more resilient rings at the proximal end of the ultrasonic horn and by one or more resilient rings at the single nodal region of the ultrasonic horn. The ultrasonic handpiece may include a pumping module located at the proximal end of the handpiece.
