Abstract:
A method for generating cut surfaces in the cornea of an eye in order to correct ametropia using an apparatus. The method includes providing the apparatus including a laser unit, which focuses pulsed laser radiation into the cornea and moves the focused radiation in the cornea to generate cut surfaces, and a control unit, which controls the laser unit for generating cut surfaces. The method includes forming at least two mutually spaced apart cut surfaces as opening cuts by application of the pulsed laser radiation from the laser unit, each opening cut extending from an anterior corneal surface into the cornea and forming a further cut surface as a relieving cut by application of the pulsed laser radiation from the laser unit, which relieving cut extends from the anterior corneal surface into the cornea. The position and shape of the relieving cut is selected such that the relieving cut contributes to the correction of the ametropia of the eye.
