The invention relates to an assembly, in particular an ophthalmologic therapy assembly, for processing a surface (11) in a processing volume (300) of a transparent material (3) by means of focused radiation (1), comprising a device for producing (100) and an optical unit (2, 200, 202) for focusing a radiation (1), comprising a device for changing (400) the position of the focus (4) of the focused radiation, and comprising a control device (500). The invention further relates to a corresponding method, to a control program product, and to a planning unit. The problem addressed by the invention is that of describing an assembly and a method for processing a surface (11) that allow work to be performed using an economical optical unit (2, 200, 202), while the surface (11) is processed with the highest quality, however. This problem is solved in by means of an assembly that is designed to perform, in any direction, a slow scanning motion of the focus (4) in the processing volume (300) of the transparent material (3) and an independent fast scanning motion of the focus (4) in a partial region (600) of the processing volume (300), which partial region can be moved in the entire processing volume (300) by means of the slow scanning motion; and by means of an assembly into which a scanning pattern is coded, which has a scanning motion having at least one lateral main component (13) in the x- and/or y-direction, on which main component components of synchronous direction-change motions in the z-direction and in the x- and/or y-direction are superposed. The problem is also solved by means of corresponding methods, a control program product, and a planning unit.

The invention relates to a treatment device (1 ) for operatively correcting defective vision of an eye (3) of a patient (4). Said treatment device comprises an interface (S) for supplying measurement data relating to parameters of the eye (3) and defective vision data relating to the defective vision of the eye (3) that is to be corrected, and a laser device (L) separating cornea tissue by applying pulsed laser radiation (2), said laser radiation (2) being focused on target points (28) situated in a pattern in the cornea (5), and a planning device (P) receiving the supplied measuring and defective vision data, also defining a volume (18) situated in the cornea (5) which covers the pupil of the eye (3) that is adapted to the obscurity, and the distance in relation to the cornea (5) produces the desired defective visual correction, determining an interface (19, 20) that delimites the defined volume (18) inside the cornea (5), and produces for said interface (19, 20) a control data set for controlling the laser device (L) that produces a three-dimensional pattern of the target points (28) in the cornea (5), situated in the interface (19, 20) and disposed such that the interface (19, 20) is embodied, after applying the pulsed laser radiation (2) according to the control data set, as an interface that isolates the delimited volume (18) in the cornea (5) and enables said volume to be extracted.

The invention relates to a method for producing cuts (9) in a transparent material, in particular in the cornea (5), by creating optical openings (8) in said material (5) by means of laser radiation (3) that is focused in said material (5), whereby the focal point (7) is displaced in order to produce the cut (9) from a surface grid-type array (F) of optical openings (8) arranged in sequence. The focal point (7) is displaced along a trajectory and optical openings (8) along said trajectory that are adjacent are not produced immediately after one another. In addition, the surface grid-type array (F) of optical openings (8) is constructed from at least two sub-grids (G,1, G2, G3), the optical openings (8) of which are processed sequentially grid by grid.

The invention relates to a method for forming curved sections (9) in a transparent material, especially in a callus (5), by producing optical openings (8) at various points in the material (5) by means of pulsed laser beams (3) focused into the material (5). The laser beam (3) is deviated in a two-dimensional manner from a deviation point in order to form the section (9) by arranging the optical openings (8) in a sequence. The two-dimensional deviation occurs such that the areas of the optical opening (8) along a curve, whereon the optical openings (8) are arranged in a sequence, are arranged at a distance in relation to the deviation point according to an angle function which is not linear and which is adapted to the curvature of the section (9). The areas along the curve adjacent to optical openings (8) inside a specific tolerance range are arranged at an even distance (d).
