  • Patent number: 10548771
    Abstract: A treatment apparatus for surgical correction of presbyopia or defective eyesight in an eye of a patient. The treatment apparatus includes a laser device configured to treat lens tissue of the eye by irradiation of pulsed laser radiation with the laser radiation being focused on target points arranged in a pattern within the lens. An interface supplies measurement data on parameters of the eye and/or defective-eyesight data on the eyesight defect to be corrected in the eye, and defines a volume located within the lens using the supplied measurement data and defective-eyesight data, the volume being defined so as to achieve the desired correction of presbyopia or defective eyesight when removed.

  • Patent number: 10531985
    Abstract: A device for machining an object by laser radiation, by photodisruption. The device includes an observation device for imaging the object and a laser scanning device by which the laser radiation is passed over a predetermined sector of the object for scanning the sector. The device includes the observation device with a first lens for imaging the object; the laser scanning device with a second lens, through which the laser radiation is guided, in which both lenses with regard to the dimension of the regions to be produced in the images and/or with regard to their focal intercept are different from each other. The device alternately images the respective region of the object in a first operating mode by the first lens and in a second operating mode by the second lens. It is thus possible to use in both operating modes a lens adapted to the intended imaging purpose.

  • Patent number: 10517761
    Abstract: Systems and methods for localizing intraocular lens and/or existing refractive index patterns, to laser write-patterns, and to refractive index patterns in order to modify the refractive index by application of femtosecond laser pulses. OCT-based confocal detection and sectional image systems are provided for localization purposes, the systems being particularly suitable for the detection of phase patterns in addition to the localization of the IOL. With respect to laser write-patterns, the modification of existing refractive index patterns in the IOL is carried out by destroying existing structures or supplementing existing refractive index patterns.
