Abstract: A device for therapeutic treatment of the retina includes a holding and positioning device for holding an optical lens element in a defined position and orientation in front of the eye of a patient, the lens element having a irradiation-transmitting concave surface for resting on the closed eyelid, and the irradiation source cooperating with the optical lens element to deliver the therapeutically effective irradiation to the retina via the optical lens element.

Abstract: A device for correcting or mitigating refractive errors in the eye presents a solution in which desired improvements in eyesight are achieved as far as possible without limiting everyday activities and where performing the treatment itself involves minimum risk. The device creates an aperture diaphragm in an eye, and has a control unit for a laser unit, the control unit being designed to control the laser unit to create the aperture diaphragm in a lens of the eye, wherein the aperture diaphragm is used to increase the depth of focus of the eye and is formed by laser-induced lesions which reduce light transmission through a lens aperture region surrounding an aperture opening.

Abstract: The invention relates to a controller for a surgical laser. According to the invention, the controller is adapted to control a laser in order to produce two or more three-dimensional compression zones, each comprising a plurality of lesions, inside a lens cortex of a crystalline lens of the eye using a laser pulse or multiple laser pulses, wherein the controller is adapted such that a laser can be calibrated with respect to a reference point within the lens, and each of the compression zones produced has a length in a radial direction, a depth in a direction parallel to the optical or visual axis and an average width in a direction parallel to a tangent of the lens cortex, wherein the sum of the average widths of all compression zones is 0.1 to 2 millimeter for every 1 diopter of desired gain in accommodation amplitude of the lens.

Abstract: A Device for producing cuts or perforations on a human or animal eye at the anterior or posterior opening of the eye lens (capsulatomy, rhexis) with a cutting element that can be inserted into the interior of the eye and a drive device which is arranged outside of the eye in order to cause movement, in particular oscillatory vibrations or rotation of the cutting element inside the interior of the eye, the drive device having a field generator for generating a magnetic or electromagnetic excitation field and the cutting element can be excited, in particular driven, by way of the excitation field generated by the field generator.

Abstract: An optical arrangement for ascertaining the orientation of an artificial lens in an eye comprises an observation beam path with an imaging optical system, at least two light-emitting test objects with a defined contour, and one collimation optical system paired with each test object for collimating the light pattern emanating from the test object in a collimation beam path that is directed at the eye. The imaging optical system is designed such that said optical system has multiple observation beam paths with different imaging properties in order to simultaneously image multiple reflected light patterns from different depths of the eye, or the imaging properties of the observation beam paths can be adjusted in a variable manner in order to be able to sharply image sequentially reflected light patterns from different depths.
