Abstract
An apparatus for generating cut surfaces in the cornea of an eye in order to correct ametropia is provided, said apparatus comprising a laser unit, which can focus pulsed laser radiation into the cornea and move it therein in order to generate cut surfaces, and a control unit, which controls the laser unit for generating cut surfaces such that a predetermined lenticle to be removed is separated from the surrounding corneal material in the cornea by at least one cut surface, and that at least two mutually spaced apart cut surfaces are formed as opening cuts, each extending from the lenticle to the anterior corneal surface, the position and shape of the opening cuts being selected such that the opening cuts contribute to the correction of the ametropia of the eye or do not counteract the correction of the ametropia of the eye.
