Corneal Cutter Or Guide For Corneal Cutter Patents (Class 606/166)
  • Patent number: 11007080
    Abstract: The present disclosure provides a system and method for cutting a flap in laser ophthalmic surgery using polarization sensitive optical coherence tomography (PS-OCT). The system includes a PS-OCT system, a femtosecond laser, control device, and processor. The PS-OCT system includes a PS-OCT source, a polarization component, a reference reflector, a beam splitter, a wave plate, and a detector. The processor receives data relating to an interference pattern of a reflected PS-OCT beam, received at the detector, determines a relative fiber orientation of the sample, determines whether a photodisruption pattern generated by the femtosecond laser to cut the flap should be adjusted horizontally or vertically, based on the relative fiber orientation, and may generate a control signal to adjust the photodisruption pattern generated by the femtosecond laser. The disclosure further provides a method for cutting a flap on an eye using PS-OCT.

  • Patent number: 10945885
    Abstract: A microsurgical device and methods of its use can be used for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. A dual-blade device can be used for cutting the trabecular meshwork (“TM”) in the eye. The device tip provides entry into the Schlemm's canal via its size (i.e., for example, 0.2-0.3 mm width) and configuration where a ramp elevates the TM away from the outer wall of the Schlemm's canal and guides the TM to first and second lateral elements for creating first and second incisions through the TM. The dimensions and configuration of the blade is such that an entire strip of TM is removed without leaving TM leaflets behind and without causing collateral damage to adjacent tissues.

  • Patent number: 9339415
    Abstract: A surgical blade may include a surgical incision guide configured to guide a surgical incision. The surgical incision guide may include one or more surgical incision guide marks. A surgical incision guide mark may be configured to provide information about a surgical incision. For example, a surgeon may compare a location of a surgical incision guide with a portion of a tissue to identify an incision depth. Illustratively, a surgeon may compare a location of a surgical incision guide with a portion of a tissue to identify an optimum incision depth to adjust an orientation of a surgical blade.

  • Patent number: 9326848
    Abstract: The actuator comprises a barrel and a plunger received within the barrel. A clutch mechanism is operable between the plunger and the barrel. The clutch mechanism includes a driven member and a fixed member having respective castellations. The driven member carries pins which engage a three-start thread on the plunger. The castellations are urged into engagement by three annular springs. In the engaged condition of the clutch, the plunger is advanced by rotation relative to the barrel. An axial load on the plunger disengages the clutch mechanism, allowing the plunger to be advanced axially while rotating the driven member. Two-handed or one-handed operation according to a user's choice is therefore possible. The actuator can be used in combination with a lens delivery device.

  • Patent number: 9198574
    Abstract: An eye examination aid including an aligner/illuminator and a mount. The aligner/illuminator includes a first body containing a visible light laser and an illumination source emitting non-coherent light. The visible light laser has a laser axis along which visible laser light is emitted. The mount includes a second body having a receiving portion into which the aligner/illuminator is removably receivable in a fixed orientation and presenting a first generally planar side oriented substantially parallel to the laser axis and a second generally planar side oriented substantially perpendicular to the laser axis. At least one of the first generally planar side and the second generally planar side are structured to receive an adhesive whereby the mount is adapted to be secured to an external surface of a refractor instrument such that the laser axis is directed substantially parallel to an optical axis of the refractor instrument.

  • Patent number: 9144516
    Abstract: The invention relates to a device for intraocular administration of a substance, for example a medication, into a human or animal eye by means of a hypodermic needle. Until recently, intravitreal or intraocular injections, by which a substance, and more in particular a medication, is injected into a human or animal eye by means of a hypodermic needle, were only used in exceptional cases. Especially in the treatment of endophtalmitis, an infrequently occurring intraocular inflammation of the eye, antibiotics are often administered intravitreally. The object of the invention is to provide a tool which makes it possible, using one instrument, to keep the eye stationary and at the same time facilitate giving the injection, which will be carried out under identical, reproducible circumstances at all times in that case.

  • Patent number: 9125731
    Abstract: A microkeratome cutting head includes a head structure, an applanation plate, and a stromal plate. The head structure may include a blade cavity for receiving a blade and a blade opening through which the blade extends. The blade is configured for creating a corneal flap at a corneal flap thickness. The applanation plate is disposed at an elevation above the stromal plate plane. The elevation difference is approximately equal to the corneal flap thickness. An artificial anterior chamber (AAC) system is used to hold the donor eye for interfacing with the microkeratome. The AAC system includes an optional pressure valve and pressure gauge in a closed loop system for the user or surgeon to control line pressure applied to the donor eye during the procedure.

  • Patent number: 9011470
    Abstract: A toric axis marker has a handle, a coaxial tip, a head upon the tip, a dial axially above the head, and a marker head with two blades connecting to the dial. The dial and blades rotate simultaneously and concentrically upon the head. The head and its components have a central aperture for a surgeon to use in positioning the marker relative to the center of an eye. The marker head has its two blades upon a common diameter. The dial has two symmetric arcuate windows that reveal an angle scale. The marker body has an inwardly offset angle to the handle. Each blade has a blunt edge outwardly from the marker head and a slightly curved shape that conforms to the shape of an eyeball, proximate the cornea. With the blades positioned, a surgeon marks the cornea with an ink for incision locations.
