摘要: A method for determining the topography of the cornea of an eye on the basis of an optical, contactless data capture. In the method for determining the topography of the cornea of an eye, which is based on a deflectometric method, the deflectometric measurements are carried out with the aid of a keratometric method by virtue of additional OCT-based scans being made at the keratometric measurement points, wherein the two measurement systems are registered to one another and both the keratometric and the OCT-based measurement values are recorded and used for mutual calibration to determine and output the topographic data. The proposed method serves to determine the topography of the cornea of an eye. It is helpful to ascertain the topography in order to be able to draw conclusions about possible pathological changes. Moreover, the exact measurement of the corneal topography is of great importance for correcting refractive errors.

摘要: An eye surgery system 1 comprises microscopy optics 3 and an OCT device 5 to generate a light-optical image and an OCT image of an eye fundus 11, a controller 29 and a visualization system 13, 41, 83. The controller comprises a data interface 97 for receiving a preoperative OCT image and may control the visualization system to display a representation of the received preoperative OCT image. The controller may control the OCT device 5 to record an intraoperative OCT image and may control the visualization system to display a representation of the recorded intraoperative OCT image. The controller may adjust a magnification of the representation of the intraoperative OCT image and/or a magnification of the representation of the preoperative OCT image so that the magnifications of the representation of the intraoperative OCT image and the magnification of the representation of the preoperative OCT image are equal.

摘要: An ophthalmosurgical injector system includes an injector, which has a handpiece, a plunger and a dispensing device; an intraocular lens, which has an optic body, a C-shaped first haptic arm protruding from the optic body and a C-shaped second haptic arm protruding from the optic body; a cartridge, in which the intraocular lens is received, wherein the cartridge is inserted in the injector; and an actuation element, which has a contact surface, and a locking element, with which a position of the plunger relative to the handpiece or to the cartridge can be locked. The plunger can be locked in a first position, in which the intraocular lens is held in the cartridge in a compressed and pretensioned state in which an outer distance from the first haptic arm to the second haptic arm is greater than 8 mm and less than 11 mm.

摘要: A microscopy system and a microscopy method for recording a fluorescence image and a white-light image are disclosed. An exemplary microscopy system includes an illumination apparatus for illuminating an object region and for exciting at least one fluorescent dye, an optical unit for imaging the object region onto at least one fluorescence image detector and at least one white-light image detector. A beam splitter and a filter are arranged in the beam path provided by the optical unit and configured such that substantially only fluorescence emitted by the fluorescent dyes is incident on the fluorescence image detector and an image that is as color-neutral as possible is recorded by the white-light image detector.

摘要: The invention is directed to a method of operating an ophthalmosurgical system which includes a console for accommodating an irrigation fluid vessel containing irrigation fluid and a cassette, insertable into the console, for directing the irrigation fluid to a surgical instrument for an eye to be treated. An irrigation fluid flow path leads from the irrigation fluid vessel to the cassette and to the surgical instrument. A first fluid pump includes a first pump chamber having a first volume and a first drive chamber separated therefrom by a first elastic partition and having a second volume. A second fluid pump is arranged in parallel to the first fluid pump and includes a second pump chamber having a third volume and a second drive chamber separated therefrom by a second elastic partition and having a fourth volume.

摘要: Postoperative lens position is predicted on the basis of known measured values, such as the corneal thickness, the depth of the anterior chamber, the eye length, and the distances of the capsular bag equator and/or of the lens haptic from the anterior surface of the lens. In addition, the calculation also takes into account the attitude of the intraocular lens, for which purpose additional parameters of the pseudophakic eye are used that have not previously been taken into consideration. The proposed method is suitable for a more exact prediction of the strength and nature of an intraocular lens to be implanted in a pseudophakic eye in the context of cataract surgery or of a refractive intervention. The method is based on the use of suitable calculation methods, e.g. geometric optical formulae, or of ray tracing.

摘要: A cartridge accommodates an intraocular lens and includes first and second cartridge parts pivotally moveable relative to each other to define an open state and a closed state. The first cartridge part has a first base element and a first plate-like wing extending from the first base element. The second cartridge part has a second base element and a second plate-like wing extending from the second base element. The first and second base elements conjointly define a receiving chamber for the lens when the first and second cartridge parts are in the closed state. A lubricant feed arrangement supplies a lubricant for the lens into the receiving chamber from outside of the cartridge when the cartridge is in the closed state. The lubricant feed arrangement includes a feed channel which is formed in one of the cartridge parts and opens into the receiving chamber.

摘要: An ophthalmologic laser device includes a pulsed laser configured to produce radiation focused along at treatment beam path. A variably adjustable beam deflector unit and a focusing lens system are disposed in the treatment beam path. The deflector unit is configured to focus the radiation in different target volumes. Measuring equipment is configured to determine a shape and position of optical interfaces along a detection beam path. A control unit is configured to control the laser and the deflector unit and to implement steps including determining a shape and position of an interface of a membrane of a capsular bag of an eye located in a treatment area using the measuring equipment, determining coordinates of a target volume such that, on irradiation of the target volume, a pressure wave runs from the target volume to the anterior or posterior membrane, and adjusting the deflector unit to the target determined volume.
