  • Publication number: 20120083775
    Abstract: A device for machining the human cornea with focused laser radiation includes controllable components for setting the location of the radiation focus, a control computer for controlling these components, and also a control program for the control computer. The control program contains instructions that have been designed to bring about, upon execution by the control computer, the generation of incisions in the cornea in accordance with a predetermined incision figure, the incision figure defining a corneal bed, a flap situated on the bed and also at least one tissue strip situated in the region of the peripheral edge of the flap between the bed and the flap and extending along the edge of the flap. After the flap has been folded away, the tissue strip has to be removed and enables a creaseless post-ablative close fitting of the folded-back flap against the surface of the bed. In this manner, microstriae which may impair the visual capacity can be avoided.

  • Publication number: 20120080586
    Abstract: A process is proposed for testing a laser device that has been set up to emit pulsed focused laser radiation, the focal position of which is adjustable both in and across the direction of propagation of the laser radiation. The laser device includes a contact element that is transparent to the laser radiation, with an abutment surface for abutment of an object to be machined. Within the scope of the process, a test object that is transparent to the laser radiation at least in a machining region is applied onto the abutment surface of the contact element. Then laser radiation is beamed into the test object bearing against the abutment surface and in the process the focal position is moved in accordance with a predetermined test pattern, in order to generate enduring machining structures in the test object.

  • Patent number: 8017905
    Abstract: In a method of calibrating the pulse energy of a laser device which provides pulsed working laser radiation, by means of the working laser radiation, multiple test ablations, in particular multiple-pulse test ablations, are carried out on one or more test objects, each with different pulse energy. The ablation depth of each of the test ablations is measured, and then, on the basis of the measured ablation depths and a specified setpoint ablation depth, an associated setpoint pulse energy is determined and set on the laser device. According to the invention, the ablation depths are measured by means of a coherent optical interferometric measuring device. The invention also concerns a laser device, in particular to carry out the above method.

  • Patent number: 7998135
    Abstract: A device for ophthalmologically treating the eye has a treatment laser beam (UV) for ablating parts of the cornea (12) and a fixation light beam (24). A fixation light spot in the vicinity of the fovea (30) and the fovea are imaged by means of a camera (40). This makes it possible to check whether the patient has reliably fixated the fixation light source (22). In addition, the pupil can be recorded and both recordings can be superimposed.

  • Publication number: 20110184394
    Abstract: A device for machining the human cornea with focused pulsed femtosecond laser radiation comprises scanner components for local setting of the beam focus, a control computer for controlling the scanner components, and a control program for the control computer. The control program contains instructions that upon execution by the control computer are designed to bring about the generation of an incision figure in the cornea encompassing a flap incision (38, 40). In accordance with the invention the incision figure further encompasses an auxiliary incision (50) connected with the flap incision and leading locally, preferentially directly, away from the latter as far as the surface of the cornea. The auxiliary incision is expediently generated temporally ahead of the flap incision and forms a discharge channel through which gases can escape that may arise in the course of the cutting of the flap incision.

  • Publication number: 20110134390
    Abstract: An artificial eye model for use in ophthalmological measurements exhibits a simulation of at least one eye structure, for instance of a cornea or of a crystalline lens. In accordance with the invention the simulation possesses fluorescent properties. In this way, a beam expansion as a result of multiple scattering in the case of scattered-light-based photographic recordings can be avoided. Instead of this, a sharp-contour imaging of the simulated eye structures is made possible.

  • Publication number: 20110040292
    Abstract: An apparatus for ophthalmological, in particular refractive, laser surgery includes a laser-beam source (20) for emitting a focused treatment laser beam (20?) and also includes an optical-coherence interferometric measuring device (34), for example an OLCR pachymeter, for measuring the z-position of a predetermined point of an eye to be treated in the coordinate system of the laser-surgery apparatus. A computer (C) serving as evaluating and control unit has been set up to assess, on the basis of the measured z-position, whether a desired treatment point of the eye in the z-direction falls in the focal plane of the treatment laser beam or is offset in relation to said plane. Depending on whether or not the patient is correctly positioned in relation to the focal plane, the computer (C) can bring about a range of actions.

The light emitted by the radiation source can have a wavelength range in which the treatment region is partially transmissive. The treatment region can be the cornea. The reaction brought about in the treatment region by the light can be an ablation of tissue. The reaction brought about in the treatment region by the light can also be a laser-induced optical perforation of tissue, which is also referred to as photo-disruption. The radiation source can be a laser source.
