Ophthalmological apparatus for applying laser radiation into the eye for the examination and/or laser-surgical treatment of the cornea of the eye and the crystalline lens, comprising: - a femtosecond laser as a radiation source for the laser radiation, - an input optical unit having a lens and a converging lens, - an objective, from which a beam emerges in focus in the direction of the eye, - optical assemblies, - which are disposed upstream of the objective in the radiation direction and - which are provided functionally connected to the objective for the purposes of varying the focal position in the coordinate directions X, Y and Z, selectively within the region of the cornea of the eye or within the region of the crystalline lens, - the objective itself being movable relative to the eye or comprising at least one lens group (15.1, 15.2), the relative position of which is changeable in relation to the eye, - characterized in that - the focal position can be displaced from the region of the cornea of the eye into the region of the crystalline lens, and vice versa, by varying the relative position of the at least one lens group (15.1, 15.2) or of the entire objective, - with the diameter of the beam emerging from the input optical unit being variable by varying the ratio of the absolute values of the refractive powers of the lens and the converging lens and consequently the eye-side aperture angle α being changeable, - and with the eye-side aperture angle α being smaller when focussing on the region of the crystalline lens than when focussing on the region of the cornea of the eye. - a femtosecond laser as a radiation source for the laser radiation, - an input optical unit having a lens and a converging lens, - an objective, from which a beam emerges in focus in the direction of the eye, - optical assemblies, - which are disposed upstream of the objective in the radiation direction and - which are provided functionally connected to the objective for the purposes of varying the focal position in the coordinate directions X, Y and Z, selectively within the region of the cornea of the eye or within the region of the crystalline lens, - which are disposed upstream of the objective in the radiation direction and - which are provided functionally connected to the objective for the purposes of varying the focal position in the coordinate directions X, Y and Z, selectively within the region of the cornea of the eye or within the region of the crystalline lens, - the objective itself being movable relative to the eye or comprising at least one lens group (15.1, 15.2), the relative position of which is changeable in relation to the eye, - characterized in that - the focal position can be displaced from the region of the cornea of the eye into the region of the crystalline lens, and vice versa, by varying the relative position of the at least one lens group (15.1, 15.2) or of the entire objective, - with the diameter of the beam emerging from the input optical unit being variable by varying the ratio of the absolute values of the refractive powers of the lens and the converging lens and consequently the eye-side aperture angle α being changeable, - and with the eye-side aperture angle α being smaller when focussing on the region of the crystalline lens than when focussing on the region of the cornea of the eye.
