Abstract
A device for isolating a lenticle in the cornea of an eye. The device includes: a laser beam source to emit pulsed laser radiation having a pulse frequency of 1.2 MHz to 10 MHz, a pulse energy of 1 nJ to 200 nJ and a wavelength penetrating the cornea; a beam-forming unit having beam optics with an image field and that bundles pulsed laser radiation into a focus located inside the image field, and which has a maximum diameter of less than 3 μm; a beam-deflection unit shifting the focus in the cornea and inside the image field, the focus moving along a path when the image field is resting; and a control unit to control the source and the beam-forming unit to isolate the lenticle by specifying the path. The lenticle is delimited by a cut surface which is curved with regard to a front surface of the cornea.
