    摘要： Systems, devices, and methods for treating a glaucomatous eye are provided. An amount of pulsed laser energy is delivered to the pars plana of the eye by a hand-holdable device which comprises a hand-holdable elongate member and a contact member disposed on an end of the elongate member. A contact surface of the contact member is placed in direct contact with the eye so that a reference edge of the contact member aligns with the limbus and a treatment axis defined by the elongate member is angularly offset from the optical axis of the eye. The amount of pulsed laser energy delivered is insufficient to effect therapeutic photocoagulation but is sufficient to increase uveoscleral outflow so as to maintain a reduction from pre-laser treatment intraocular pressure. Amounts of pulsed laser energy will be transmitted to a circumferential series of tissue regions of the eye.

    摘要： An ophthalmological apparatus includes a handle for manually holding and applying the ophthalmological apparatus, fastening has abilities for fixing the ophthalmological apparatus at an eye, a light source, and a light projector for the focused projection of light pulses for punctiform tissue breakdown at a focal point in the interior of the eye tissue. The ophthalmological apparatus also includes a movement driver for moving the light projector. The movement of the light projector and therefore that of the focal point with the assistance of the movement driver permits a dimensioning of the optical projection system of the light projector which is substantially smaller than in the case of an ophthalmological apparatus where the focal point is moved exclusively by an optical projection system.

    摘要： An apparatus and method are provided for performing ocular laser surgery using a patient interface having a posterior contact surface that may include surface irregularities that were generated during manufacturing of the patient interface. A beam delivery system having a focusing lens, scanning subsystem and adaptive optic (e.g. deformable mirror) is provided for guiding the surgical laser beam through the patient interface and to a desired focal spot location. An optical detector generates image data representing the posterior patient interface surface which is then processed by a computer system to identify surface irregularities by comparing the image data to a reference surface or axis. In particular, a surface irregularity can be identified as having a z-axis component; a tilt component and a surface profile component. Each irregularity component can be compensated separately by sending an adjustment signal to one of the beam delivery system components.

    摘要： Apparatus and methods are provided for interfacing a surgical laser with an eye using a patient interface device that minimizes aberrations through a combination of a contact lens surface positioning and a liquid medium between an anterior surface of the eye and the contact lens surface. Further, support rings, ocular stability devices, and methods for interfacing an eye during laser surgery are provided. In an embodiment, by way of example only, a support ring includes a first end surface, a second end surface opposite the first end surface, and an outer surface extending between the first end surface and the second end surface. The second end surface has a width that is greater than a width of the first end surface and extends toward a central opening in the support ring to define a concave curvature configured to substantially match a curvature of a patient's eye. The outer surface includes an annular groove formed adjacent the first end surface and a plurality of exterior vacuum channels spaced around the annular groove and extends axially from the annular groove to the second end surface.

    摘要： An apparatus to treat a patient comprises a laser beam, a measurement module, a scanner and a curved patient interface lens. The curved patient interface is measured with a pattern so as to determine a plurality of distances of the curved surface at a plurality of measurement locations. The measurement pattern may comprise the plurality of measurement locations distributed about a central measurement axis corresponding to the laser treatment axis. The plurality of measurement locations of the curved surface may correspond to a portion of a planned treatment profile, such that the measured distances correspond to alignment of the planned treatment. The plurality of distances can be used to determine an apex of the curved surface of the patient interface and to align the laser treatment axis with the apex of the curved surface.

    摘要： Systems and methods are described for stabilizing an eye for an ocular laser procedure while minimizing corneal distortions which can adversely affect a surgical laser beam. For the systems, a patient interface includes a contact element for stabilizing the eye and establishing a conformal interface with the anterior surface of the cornea. More specifically, devices are disclosed which overlay both a central corneal region and a peripheral corneal region. In some embodiments, a first material is used in the contact element to overlay the central corneal region and a second material is used in the contact element to overlay the peripheral corneal region. Typically, the first and second materials differ in terms of hardness and deformability. In another embodiment disclosed herein, a contact element having a viscoelastic material for stabilizing an eye for a laser procedure is described.

    摘要： A process for producing an interface unit and also a group of such interface units are specified. The interface unit exhibits a first reference surface for beaming in radiation, a second reference surface for emitting the radiation, and an axis extending in the direction from the first to the second reference surface. The production process comprises the steps of setting an optical path length of the interface unit between the first and second reference surfaces along the axis and the fixing of the set optical path length of the interface unit. The optical path length of the interface unit is set in such a way that radiation of a defined numerical aperture beamed in at the first reference surface exhibits a focus location that is predetermined with respect to the second reference surface in the direction of the axis. A precise and uniform focus location with respect to the second reference surface is obtained.
