摘要： A system for positioning the eye of a patient, relative to a stationary surgical laser unit, includes a chair for moving the patient. An eye stabilizing element is held against the eye, with a tapered receptacle extending outwardly therefrom. Also, an alignment device with a tapered tip is mounted on the surgical laser unit. In operation, the patient is moved to engage the receptacle of the eye stabilizing element with the tip of the alignment device, to thereby align the patient's eye with the surgical laser unit for laser surgery.

摘要： A method for ocular surgery requires use of a delivery system for generating and guiding a surgical laser beam to a focal point in a treatment area of an eye. Additionally, a contact device is employed for using the eye to establish a reference datum. Further, an optical detector is coupled to the beam path of the surgical laser to create a sequence of cross-sectional images. Each image visualizes both the reference datum and the focal point. Operationally, a computer then uses these images to position and move the focal point in the treatment area relative to the reference datum for surgery.

摘要： A system for performing a corneal transplantation includes a laser source for generating a laser beam and a chair for positioning a patient relative to the laser source. A stabilizing element, engageable with the laser source, is fixated on the anterior surface of the patient's cornea to hold the cornea in alignment with the laser source. The laser source is then used to remove diseased tissue from the cornea of the patient, thereby creating a corneal cavity of known dimensions. In a subsequent step, a donor graft that was previously photoaltered to have substantially the same dimensions as the corneal cavity, is transplanted into the corneal cavity.

摘要： A system for accurately guiding a laser focal point along a predetermined path within the stroma of a cornea includes a contact lens for conforming the anterior surface of the cornea to a radius of curvature, Rlens, that is approximately 8.3 mm. Conforming the cornea to the lens causes minimal discomfort to the patient and does not upset the three-dimensional architecture of the corneal lamellae. As the focal point is advanced along a path within the cornea, the laser source is selectively translated parallel to the optical axis of the cornea to control the depth of the laser focal point. The movement includes three components: a first component, z1 that is dependent upon the shape of the contact lens, a second component, z2 that compensates for refraction at the surfaces of the contact lens, and a third component, z3, that compensates for refraction caused by the anatomical configuration of the cornea.

摘要： A method is disclosed for photodisrupting a surface in the stroma of an eye at a substantially constant distance from the anterior surface of the eye. A frame of reference is established for the eye that includes an axis of rotation. Next, the focal point of a laser beam is positioned in the stroma at a radial distance from the axis. At least one laser pulse is delivered to the stromal tissue at the focal point, photodisrupting the tissue there and creating a photodisruption bubble having a diameter “d”. The focal point is then rotated about the axis through an arc length substantially equal to “d” and the photodisruption step is repeated. During rotation, the distance between the focal point and the axis is decreased at a rate substantially equal to the distance “d” per revolution. The method can be used to create a flap for a LASIK type procedure.

摘要： A device and method for steering a laser beam to a focal point in target tissue requires generating a laser beam. Diversions of the laser beam from a central beam path are minimized by a sequential arrangement of optical steering components. In order, the beam is first directed to the center of a z-scanning apparatus which will move the focal point in the medium in a z-direction. The beam is then passed to the center of a first galvanometric mirror which introduces focal point movements in the x-direction. A second galvanometric mirror then compensates for the x-direction movement by redirecting the beam to the center of a third galvanometric mirror where focal point movements in the y-direction are introduced.
