  • Patent number: 11369517
    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: 10772764
    Abstract: An adapter for coupling a laser treatment device to an object for treatment. The adapter has an input side, which may be fixed relative to the laser treatment device, by a locking mechanism and which may be fixed to the object, for alignment of the object relative to the laser treatment device. A scanned laser beam is introduced on the input side, from the laser treatment device, along a beam path to the object with a reference structure. The reference structure lies on the beam path of the adapter and may be optically detected by means of the laser beam scanned over the region.

  • Patent number: 8944601
    Abstract: The invention relates to a contact glass for ophthalmic surgery. Said glass comprises a lens body that is held in a frame and a front lens surface that is designed to be placed against the eye. According to the invention, the front lens surface is concave and follows a surface curvature (K) and an annular gap is formed at the edge of the front lens surface between the lens body and the frame, said gap being used to apply a negative pressure in order to fix the contact glass to the eye. The frame is designed to follow the contour of an imaginary continuation of the surface curvature (K), or at least does not project beyond the latter.

  • Publication number: 20140288539
    Abstract: An ophthalmic laser device with a treatment beam path that includes a variably adjustable modulator. The ophthalmic laser device is adapted to determine for the radiation pulses to be inputted into the tissue a power density to be inputted into the relevant target volume through the treatment beam path depending on a spatial distance between two target volumes of immediately successive radiation pulses and to adjust the modulator parallel in time with the control of the deflecting unit such that the relevant pulse in the target volume has the determined power density.

  • Patent number: 8425494
    Abstract: An adapter for mechanically coupling a laser processing device to an object. The adapter has a central region which can be moved into the beam path of the laser processing device and a peripheral region located outside the central region. The beam path extends up to the object along an optical axis. The adapter is fixable to the laser processing device on the one hand and provided so as to contact the object with its central region on the other hand. A fixture is provided at the peripheral region that allows the adapter to be releasably fixed to a receiving part of the laser processing device such that, upon application of a determined pulling force along the optical axis, the The fixture is removable from the receiving part.

  • Patent number: 8262223
    Abstract: The present solution is directed to the orientation of an eye for diagnostic and/or therapeutic purposes, wherein the line of sight need not coincide with the optical axis of the examination apparatus or treatment apparatus. The invention includes a fixating light source for generating a positionable fixating mark, a device for coupling this fixating mark into a beam path of an ophthalmological apparatus whose imaging optics project the fixating mark on the eye to be examined and/or treated, and a control unit by which the image of the fixating mark can be displayed at different distances and angular positions with respect to the optical axis of the ophthalmological apparatus so that the eye to be examined and/or treated is oriented to this fixating mark by foveal focusing and occupies a defined position with respect to the optical axis of the ophthalmological apparatus.

  • Patent number: 7976155
    Abstract: An adapter to be applied in contact with an anterior corneal surface. The adapter includes a contact glass portion having a corneal contact surface curvature that is flatter than the undeformed anterior corneal surface. When the contact glass is applied the cornea assumes a deformed state corneal curvature that is parallel to the flatter corneal contact surface curvature. A mount portion circumferentially surrounds the contact glass portion and defines a suction duct that is structured to secure the adapter to the cornea by negative pressure when the suction duct is brought into contact with a surface of the eye surrounding the contact glass portion. The suction duct is partially defined by a peripheral edge of the mount that extends outwardly away from the mount portion and toward but not intersecting or extending beyond a geometric continuation of the corneal contact surface curvature.

  • Patent number: 7810927
    Abstract: A solution by which an examination of the cornea for possible encapsulations, air bubbles, or other irregularities following a refractive surgery can be carried out directly at the treatment device instead of the patient having to be transferred to an examination device. The additional slit illumination system includes two slit projector units substantially symmetrically mounted at an angle of about 40° to the optical axis of the refractive treatment device, and fixed and focused on the eye of the patient to be examined. The slit projector units include a light source, a projection optical system, and beam forming and/or conducting optical components. Although intended for surgical microscopes, it can also be used for other opthalmologic treatment devices that would benefit from a slit projection system for the examination before, during, or after the treatment procedure.
