Abstract: Embodiments described herein provide ophthalmic surgical instruments. One embodiment provides an instrument including an infusion sleeve, aspiration tube, and infusion/aspiration tip. The sleeve can include a body defining an infusion channel. The tube can be in the infusion channel and define an aspiration channel. The tip can conform to the distal end of the tube. The tip can seal a gap between the sleeve and tube and can include a flange with a profile (e.g., a tapered portion) corresponding to the profile of the sleeve. The sleeve and tip can be keyed such that the sleeve directs fluid in one direction and the tip draws fluid perpendicularly from that direction. The tip's aspiration channel can extend distally beyond its aspiration port. The tip can extend to a point adjacent to an infusion port of the sleeve. A disposable component (including an aspiration tube and infusion/aspiration tip) for use with instruments is provided.

Abstract: Designs and techniques for constructing and operating femtosecond pulse lasers are provided. One example of a laser engine includes an oscillator that generates and outputs a beam of femtosecond seed pulses, a stretcher-compressor that stretches a duration of the seed pulses, and an amplifier that receives the stretched seed pulses, amplifies an amplitude of selected stretched seed pulses to create amplified stretched pulses, and outputs a laser beam of amplified stretched pulses back to the stretcher-compressor that compresses their duration and outputs a laser beam of femtosecond pulses. The amplifier includes a dispersion controller that compensates a dispersion of the amplified stretched pulses, making the repetition rate of the laser adjustable between procedures or according to the speed of scanning. The laser engine can be compact with a total optical path of less than 500 meters, and have a low number of optical elements, e.g. less than 50.

Abstract: Systems and methods are provided for illuminating a surface to be observed microscopically using a retractable beamsplitter. The retractable beamsplitter allows the use of coaxial illumination when the beamsplitter is positioned in the operator's line of sight. The retractable beamsplitter allows the use of non-coaxial illumination without reducing the amount of illumination that reaches the operator when the beamsplitter is retracted from the operator's line of sight. As a result a single system can be used effectively to provide various types of illumination.

Abstract: In various embodiments, a phacoemulsification cutting tip with a straight shaft and an angled portion off of the straight shaft may include a hook on the angled portion to move an axis of rotation of the cutting tip closer to alignment with an extended centerline of the shaft. The cutting tip may be configured to torsionally rotate back and forth on an axis perpendicular to a centerline of the shaft (e.g., rotation around a y-axis). In some embodiments, lateral vibrations (e.g., side to side along an x-axis or z-axis perpendicular to the y-axis) that result from torsional rotation around the y-axis in a cutting tip without the hook may be reduced through use of the hook to balance the otherwise eccentrically weighted hook.
