Abstract: Embodiments of this disclosure disclose an imaging system, including an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The beam source generates an electromagnetic radiation beam. The detection assembly generates a signal indicative of an intensity of a portion of the electromagnetic radiation beam reflected from the focal point location. A subsequent focal point of the electromagnetic radiation beam may be adjusted per the measured intensity signal. In some embodiments, an intensity signal below a lower threshold value may suggest a depth increase for a subsequent focal point. An intensity signal above an upper threshold value may suggest a depth decrease for a subsequent focal point. And, an intensity signal between the lower and upper thresholds may suggest a depth be maintained for a subsequent focal point. The focal point may be adjusted after each pulse or after a plurality of pulses.

Abstract: Methods and apparatus are configures to measure an eye without contacting the eye with a patient interface, and these measurements are used to determine alignment and placement of the incisions when the patient interface contacts the eye. The pre-contact locations of one or more structures of the eye can be used to determine corresponding post-contact locations of the one or more optical structures of the eye when the patient interface has contacted the eye, such that the laser incisions are placed at locations that promote normal vision of the eye. The incisions are positioned in relation to the pre-contact optical structures of the eye, such as an astigmatic treatment axis, nodal points of the eye, and visual axis of the eye.

Abstract: A system for laser ophthalmic surgery includes: a single laser source, under the operative control of a controller, configured to alternatively deliver a first treatment laser beam and a second treatment laser beam. The first treatment laser beam has a pulse energy of 10 to 500 μJ. The second pulsed laser beam has a second pulse energy of about 0.1 to 10 μJ, lower than the first treatment laser beam. An optical system focuses the first treatment laser beam to a first focal spot and directs the first focal spot in a first treatment pattern into a first intraocular target. The optical system also focuses the second treatment laser beam to a second focal spot and direct the second focal spot in a second treatment pattern into a second intraocular target. The first intraocular target and second intraocular target are different.

Abstract: A system for ophthalmic surgery includes a laser source configured to deliver an ultraviolet laser beam comprising laser pulses having a wavelength between 320 nm and 370 nm to photodecompose one or more intraocular targets within the eye with chromophore absorbance. The pulse energy, the pulse duration, and the focal spot are such that an irradiance at the focal spot is sufficient to photodecompose the one or more intraocular targets without exceeding a threshold of formation of a plasma and an associated cavitation event. An optical system operatively coupled to the laser source and configured to focus the ultraviolet laser beam to a focal spot and direct the focal spot in a pattern into the one or more intraocular targets. The optical system focuses the laser beam at a numerical aperture that provides for the focal spot to be scanned over a scan range of 6 mm to 10 mm.

Abstract: A method of reversibly separating an imaging assembly from an optical path in a laser surgical system includes generating an electromagnetic beam, propagating the electromagnetic beam from the beam source to a scanner along an optical path, the optical path comprising a first optical element that attenuates the electromagnetic beam, reversibly inserting a confocal bypass assembly into the optical path, diverting the electromagnetic beam along a diversion optical path around the first optical element, wherein the confocal bypass assembly automatically exits the optical path when a power loss occurs to one or more components of the system.

Abstract: The amount of energy to provide optical breakdown can be determined based on mapped optical breakdown thresholds of the treatment volume, and the laser energy can be adjusted in response to the mapped breakdown thresholds. The mapping of threshold energies can be combined with depth and lateral calibration in order to determine the location of optical breakdown along the laser beam path for an amount of energy determined based on the mapping. The mapping can be used with look up tables to determine mapped locations from one reference system to another reference system.

Abstract: Methods and systems for performing laser-assisted surgery on an eye form a layer of bubbles in the Berger's space of the eye to increase separation between the posterior portion of the lens capsule of the eye and the anterior hyaloid surface of the eye. A laser is used to form the layer of bubbles in the Berger's space. The increased separation between the posterior portion of the lens capsule and the anterior hyaloid surface can be used to facilitate subsequent incision of the posterior portion of the lens capsule with decreased risk of compromising the anterior hyaloid surface. For example, the layer of bubbles can be formed prior to performing a capsulotomy on the posterior portion of the lens capsule.
