1. A patient interface for fixing a position of an eye relative to a system for short pulse laser eye surgery, the patient interface comprising:
a contact element;
wherein the contact element comprises a unitary one piece structure, formed of a transparent or partially transparent material and includes a suction ring, a casing and an optical element proximate an upper side of the casing; and
wherein the casing defines at least one opening, to which is connectable respectively a feed line via a fixing aid or which respectively permits connection of a lead; and
wherein the casing of the contact element further comprises an optical wave guide structure, wherein the optical wave guide structure is spatially displaced from a surface of the eye, and wherein the optical wave guide structure guides optical waves independently of the optical element.
