  • Patent number: 12005001
    Abstract: In laser-assisted corneal lenticule extraction procedures, the lenticule incision profile includes anterior and posterior lenticule incisions, with one or more of the following features: plano transition zone outside the optical zone, to improve mating of anterior and posterior incision surfaces after lenticule extraction; shallow arcuate incisions above the anterior incision and near the lenticule edge, to improve surface mating; separate ring cut intersecting the anterior and posterior incisions in the transition zone, to reduce tissue bridges and minimize tear at the lenticule edges and facilitate easy lenticule extraction; larger posterior incision, which includes a pocket zone outside the lenticule edge, for better surface mating and bubble management during cutting; and a separate ring shaped pocket cut intersecting the pocket zone of the posterior incision, for bubble management.

  • Publication number: 20240180746
    Abstract: A method implemented in an ophthalmic surgical laser system that employs a resonant scanner, scan line rotator, and XY- and Z-scanners, for forming a corneal flap in a patient's eye with improved bubble management during each step of the flap creation process. A pocket cut is formed first below bed level, followed by the bed connected to the pocket cut, then by a side cut extending from the bed to the anterior corneal surface. The pocket cut includes a pocket region located below the bed level and a ramp region connecting the pocket region to the bed. The bed is formed by a hinge cut and a first ring cut at lower laser energies, followed by a bed cut and then a second ring cut, which ensures that any location in the flap bed is cut twice to minimize tissue adhesion. The side cut is formed by multiple side-cut layers at different depths which are joined together. All cuts are formed by scanning a laser scan line generated by the resonant scanner.

  • Publication number: 20240173590
    Abstract: The invention relates generally to strength training exercise equipment, and more specifically, to an exercise machine with leverage arm for strength training (or exercise machines). The machine is comprised of a multipurpose frame having a handle to which weights can be attached, where the handled is connected to the frame with a VLS system that allows for free multi-axis movement of the handle in a to recreate the movement of free weights. The machine is mobile and compact such that it can move through a standard sized doorway without adjustment or disassembly.
