An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X,Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group or objective shifts the focus position from the cornea to the lens of the eye and vice versa. |
