Abstract: A planning unit produces control data for a treatment device for eye surgery which produces at least two cutting planes in a cornea of the eye using a laser unit. The planning unit includes a calculation module for establishing cornea cutting planes and is configured to establish the cornea cutting planes based on data of a refraction correction. The cornea cutting planes are determined so as to include a cap cut, a lenticule cut, a first access cut for accessing the cap cut, and a second access cut for accessing the lenticule cut. The planning unit is also configured to produce a control data set for actuating the laser unit for the cornea cutting planes.

Abstract: A planning system generates control data for a treatment device for eye surgery that creates at least two incision surfaces in the cornea using a laser apparatus. The planning system includes a computation device configured to specify the cornea incision surfaces based on data of a refractive correction. The cornea incision surfaces include an access incision and a cap incision, with the access incision having a smaller diameter than the cap incision. The computation device being configured to generate a control data record for the cornea incision surfaces for purposes of controlling the laser apparatus.

Abstract: A method and a device for forming cut surfaces in a transparent material, particularly in the cornea, by producing optical breakthroughs in the material by application of laser radiation focused into the material. The focal point is adjusted in three dimensions to form the cut surface by the sequential arrangement of optical perforations. The focal point is guided in such a manner that cutting is divided into at least two steps, and in at least one of the steps, the formation of the cut is carried out with a path radius that decreases in size, and in one of the steps, the cut formation is carried out with a path radius that increases in size.

Abstract: A method for changing a property of an eye uses a continuously multifocal profile that includes a component for increasing a focal depth. The method includes calculating the component for increasing the focal depth to be rotation-symmetrical. Alternatively, or in addition, the calculating is carried out so as to optimize an encircled energy criterion over an extended range of depth.

Abstract: A method for the surface treatment (that is, smoothing and/or sealing) of incision surfaces in a transparent material, in particular in the cornea. For this purpose, the incision surface is subjected to the radiation of a laser (for example, UV laser, preferably excimer laser, or IR laser) and/or another suitable radiation source.
