Patent number: 11369517Abstract: 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.Type: GrantFiled: December 26, 2019Date of Patent: June 28, 2022Assignee: Carl Zeiss Meditec AGInventors: Marco Hanft, Dirk Muehlhoff, Mario Gerlach, Elke Ebert

Patent number: 10772764Abstract: 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.Type: GrantFiled: August 8, 2016Date of Patent: September 15, 2020Assignee: Carl Zeiss Meditec AGInventors: Mark Bischoff, Elke Ebert, Karsten Festag, Carsten Lang, Markus Sticker

Patent number: 8262223Abstract: 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.Type: GrantFiled: March 8, 2007Date of Patent: September 11, 2012Assignee: Carl Zeiss Meditec AGInventors: Mark Bischoff, Marco Hanft, Elke Ebert, Gregor Stobrawa

Patent number: 7976155Abstract: 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.Type: GrantFiled: March 24, 2010Date of Patent: July 12, 2011Assignee: Carl Zeiss Meditec AGInventors: Dirk Muhlhoff, Elke Ebert, Karsten Festag, Uwe Wolf

Patent number: 7810927Abstract: 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.Type: GrantFiled: November 8, 2007Date of Patent: October 12, 2010Assignee: Carl Zeiss Meditec AGInventors: Gerard Antkowiak, Marco Hanft, Elke Ebert, Karsten Festag, Juergen Ledermann
