  • Patent number: 11076917
    Abstract: A method for generating control data to control a laser device for correcting defective vision. A cut surface is specified which is curved, has a vertex and an edge, and is to be created in the eye. One or more paths, along which a focus of the laser radiation is to be adjusted, are defined for the control data and are selected such that they lie on or near the cut surface. To select the paths, a reference plane, preferably perpendicular, with respect to a direction of incidence of the laser radiation is determined, and different displacement positions are determined for said reference plane from the vertex to the edge of the cut surface. Multiple axes or semi-axes are determined for each displacement position. Intersections of the axes are connected into closed curves which are concentric or form a spiral.

  • Patent number: 11039959
    Abstract: An ophthalmic laser procedure for forming a lenticule in a cornea and extracting the lenticule from the cornea to accomplish vision correction. An ophthalmic laser system is used to form top and bottom lenticule incisions defining a lenticule in between, and further to form top and/or bottom entry cuts that respectively end unambiguously near the top or bottom lenticule surface. The bottom entry cut intersects both the top and bottom lenticule incisions but ends near the bottom lenticule incision. The entry cuts allow the surgeon to insert a surgical tool which reaches the intended top or bottom lenticule surface without ambiguity. The lenticule has an optical zone in the center that defines the optical power of the lenticule, and a transition zone in the periphery, where the end points of the entry cuts are located in the transition zone.

  • Patent number: 11039957
    Abstract: A treatment device for the surgical correction of defective vision in an eye. The device includes a laser apparatus controlled by a controller. The controller determines a desired correction of defective vision from measurement data of the eye to produce control data for the laser, and to control the laser to emit radiation according to the control data, such that a lenticule-shaped volume is isolated in the cornea. The controller computes a lenticule-shaped intended volume, the removal of which from the cornea leads to an actual correction of defective vision in an optical zone in the eye which differs from the desired correction more at the edge of the optical zone than at the center of the optical zone. The thickness of the lenticule-shaped intended volume is less than the thickness of a lenticule-shaped comparison volume, the removal of which would bring about the desired correction of defective vision.

    Abstract: A system for therapy of the eye by treating tissue with therapeutic radiation using nonlinear interaction. A laser device is provided, which delivers the therapeutic radiation. The therapeutic radiation is focussed by a focussing device in an image field, and xy scanners and z scanners shift the focus laterally and longitudinally within a treatment volume. The therapeutic radiation is either a second short pulse radiation or a first short pulse radiation, each of which have a spectral centroid within a wavelength range defined by the short pulse properties. The system is particularly corrected with regard to longitudinal chromatic aberrations and lateral chromatic aberrations such that the spectral characteristic curves of the two aberrations each have a local extreme within the wavelength ranges, and a certain tolerance within the wavelength ranges is not exceeded, therefore the characteristic curves are very shallow.

  • Patent number: 10663761
    Abstract: A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10?4 Pa*m3 to about 5×10?4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.

  • Patent number: 10648855
    Abstract: A method of detecting a spot shape of a pulsed laser beam, includes applying a pulsed laser beam having a wavelength absorbable by an inspection wafer held on a chuck table continuously to the inspection wafer with a focused point on an upper surface of the inspection wafer thereby to form a plurality of laser spots on the upper surface of the inspection wafer. An image of the laser spots is captured, and profiles of shapes of the laser spots are extracted from the captured image of the laser spots. A degree of similarity between the captured image and the profile of an ideal laser spot shape is calculated and stored in a memory. The shapes of the laser spots are found to be improper if the calculated degree of similarity is lower than a threshold value.

  • Patent number: 10617564
    Abstract: A system and method for treating a lesion on target tissue that includes a visualization device for capturing an image of target tissue containing a lesion, a light source for generating a light beam, a scanner for deflecting the light beam in the form of a treatment pattern, and a controller for determining boundaries of the lesion from the captured image, and for controlling the scanner to project the treatment pattern onto the target tissue and within the boundaries of the lesion. An alignment light source can be used to generate an alignment light beam, such that the scanner deflects the alignment light beam in the form of an alignment pattern. The controller controls the scanner to project the alignment pattern onto the target tissue to visually indicate a position of the treatment pattern on the target tissue.

  • Patent number: 10596038
    Abstract: Methods and apparatus for the treatment of the eye to reduce pain can treat at least an outer region of the tissue so as to denervate nerves extending into the inner region and reduce the pain. For example, the cornea of the eye may comprise an inner region having an epithelial defect, and an outer portion of the cornea can be treated to reduce pain of the epithelial defect. The outer portion of the cornea can be treated to denervate nerves extending from the outer portion to the inner portion. The outer portion can be treated in many ways to denervate the nerve, for example with one or more of heat, cold or a denervating noxious substance such as capsaicin. The denervation of the nerve can be reversible, such that corneal innervation can return following treatment.
