Abstract: 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.

Abstract: The invention relates to a device for machining an object by laser radiation, in particular by using the photodisruption method. Said device comprises 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 said sector. According to the invention, such a 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. This invention 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.

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.

Abstract: The invention relates to a laser treatment unit for performing eye surgery, comprising a contact glass (23), which can be placed onto the eye (21) and via which a treatment laser beam (2) passes. A safety mechanism (24, 25) is provided that displaceably holds the contact glass (23) in such a manner that the contact glass retreats when the contact glass (23) is subjected to the action of a force contrary to the direction of incidence of the laser beam. The safety mechanism (24, 25) enables this retreating when a force is greater than a force limit value (Fmin) and holds the contact glass (23) in a fixed manner when the force is less than the force limit value.
