Embodiment Construction

[0068] figure 1 A therapeutic device for ophthalmic surgery is shown and is provided with the general reference numeral 1 . The treatment device 1 is designed to introduce laser cutting at the eye 2 of a patient 3 . For this purpose, the treatment device 1 has a laser device 4 which emits laser radiation 6 from a laser source 5 which is directed as focused radiation 7 into the eye 2 or into the cornea. Preferably, the laser radiation 6 is pulsed laser radiation with a wavelength between 300 nanometers and 10 micrometers. Furthermore, the pulse length of the laser radiation 6 is in the range between 1 femtosecond and 100 nanoseconds, with a pulse repetition rate of 500 kHz and 30 MHz, preferably 1.2 to 10 MHz, and a pulse energy between 1 nanojoule and 10 μm Between joules, preferably 1 to 200 nanojoules. Thus, the treatment device 1 produces cut planes in the cornea of ​​the eye 2 by deflecting the pulsed laser radiation. For this purpose, therefore, a scanner 8 and a radi...

Abstract

The invention relates to a planning device for generating control data for a treatment device which generates at least one cutting surface in the cornea and on the treatment device by means of a laser device, the treatment device having a planning device of said type. The invention also relates to a method for generating control data for such a treatment device, as well as to a method for ophthalmic surgery. In this case, when the cutting surface is determined, the cutting surface can be rotated about an axis extending substantially parallel to the eye axis.

Description

technical field [0001] The invention relates to a planning device for generating control data for a treatment device that produces at least one cutting plane in the cornea by means of a laser device. The invention also relates to a treatment device with a planning device of the type described above. [0002] The invention also relates to a method for generating control data for a treatment device that produces at least one cutting plane in the cornea by means of a laser device. [0003] Finally, the invention also relates to a method for ophthalmic surgery, in which at least one cutting plane is produced in the cornea by means of a treatment device with a laser device. [0004] The invention also relates to a user interface for a planning device as described above. Background technique [0005] Different treatment methods aimed at refractive correction at the human eye are known in the prior art. The purpose of the surgical method is to modify the cornea in a targeted man...
