An ophthalmological implant including an imaging optical element, and a haptic with a haptic root. Also, a corresponding method for producing an ophthalmological implant and a characterization system for identifying an ophthalmological implant for example an intraocular lens. The implant includes an unambiguous label and hence an unambiguous and reliable identification option. The label is not able to be mixed-up and is possible with minimal additional technical outlay. The implant includes a rotationally symmetric structural code of identification data of the ophthalmological implant arranged on the haptic root and/or the region of the haptic proximate the haptic root. Also, a method for producing an ophthalmological implant, in which the implant receives, directly during or after the forming, a rotationally symmetric structural code of identification data.

An ophthalmo-surgical injector includes an injector body, a tip with which an intraocular lens can be pressed out of the injector, a first plunger mounted longitudinally displaceably on the injector body and having a first projection, a shaft rotatably mounted in the injector body and having a first guide and a second guide which are each wound about the shaft, and a second plunger mounted longitudinally displaceably on the injector body and having a second projection. The first projection engages in the first guide, such that the first plunger is configured to effect, with a longitudinal displacement of the first plunger, a rotation of the shaft about a longitudinal axis of the injector body, and the second projection engages in the second guide, as a result of which the shaft is configured to effect, with the rotation effected by the first plunger, a longitudinal displacement of the second plunger.

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.

The invention relates to a method for forming curved cuts in a transparent material, in particular in the cornea, by the creation of optical perforations in said material using laser radiation that is focused in the material. The focal point is displaced three-dimensionally to form the cut by lining up the optical perforations. The focal point is displaced in a first spatial direction by a displaceable lens and said focal directions, in such a way that it follows the contours of the cut, which lie on a plane that is substantially perpendicular to the first spatial direction.
