  • Patent number: 12251341
    Abstract: A system for incising tissue with a plasma comprises an elongate electrode configured to incise the tissue along a tissue incision profile and a tissue contact element configured to shape the tissue, which comprises one or more of a channel or a protrusion to form one or more of a corresponding protrusion or indentation in a tissue surface while the tissue is incised with the electrode along the incision profile. The tissue contact element shapes the tissue sufficiently to allow the tissue to form one or more complimentary features along the incision profile when the tissue relaxes to a free-standing configuration with removal of the tissue contact element. The complementary features may be incised into the tissue to provide increased mechanical stability between the separated tissue regions, such as with nominally interlocking protrusion(s) and indentation(s).

  • Publication number: 20240335325
    Abstract: An elongate electrode is supported between two arms and configured to flex and generate plasma to incise tissue. Each of the arms is configured to penetrate tissue with the electrode supported therebetween to form a pocket with an incision. Each arm may comprise a distal tip shaped to penetrate tissue, and an internal curved structure such as a track is shaped to allow the electrode to slide over the curved structure while the electrode is tensioned. The internal curved structure may comprise an electrically insulating material that provides electrical insulation to the tensioned sliding electrode. An opening formed in a lumen allows the electrode to extended between the curved structure and the exposed portion of the electrode suspended between the two arms. The separation distance between the two arms can be adjusted to vary an exposed length of the electrode to create a pocket incision of varying width.

  • Publication number: 20230190526
    Abstract: Methods and systems for performing laser-assisted surgery on an eye form one or more small anchoring capsulotomies in the lens capsule of the eye. The one or more anchoring capsulotomies are configured to accommodate corresponding anchoring features of an intraocular lens and/or to accommodate one or more drug-eluting members. A method for performing laser-assisted eye surgery on an eye having a lens capsule includes forming an anchoring capsulotomy in the lens capsule and coupling an anchoring feature of the intraocular lens with the anchoring capsulotomy. The anchoring capsulotomy is formed by using a laser to incise the lens capsule. The anchoring feature can protrude transverse to a surface of the intraocular lens that interfaces with the lens capsule adjacent to the anchoring capsulotomy.

  • Publication number: 20210361485
    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 ?J. The second pulsed laser beam has a second pulse energy of about 0.1 to 10 ?J, 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.

  • Publication number: 20200390597
    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.
