Abstract: A system including: a contact element for fixing the relative geometric position and orientation of a patient's eye with respect to a laser applicator and a lens element for insertion into the contact element. The contact element receives the lens element at a predetermined position. The lens element has an eye surface and the lens element has a projection element that engages with one or several holding elements from below for fastening the lens element in the contact element by a snap-action connection. The lens element presents a lens contact surface on a lower side of a projection element. The at least one projection element engages the at least one holding element. The lens contact surface is pressed against an elastic compensation element arranged on a fastening surface of the contact element and serving to reduce the forces acting on the lens element by the at least one holding element.
