1. A patient interface system for positioning a patient's eye relative to a laser device for laser surgery, comprising:
a patient interface for coupling to the patient's eye; and
a patient interface holder for arranging the patient interface on the laser device, wherein
the patient interface comprises a first positioning device for abutting the patient interface on the patient's eye and a second positioning device for positioning the patient interface relative to the patient interface holder, the second positioning device having collars,
the patient interface holder includes a holding device with two opposing, groove-shaped guiding devices along which the collars of the second positioning device of the patient interface are forcibly guided and slidable for coupling and decoupling, along a linear coupling path, the patient interface and the patient interface holder, the linear coupling path being substantially perpendicular to a direction of an intended laser radiation of the laser device through the patient interface system,
the patient interface holder comprises a suction duct connectable to a suction device, the suction duct of the patient interface holder including a male connector,
the patient interface comprises a fluid-conducting device including a female fitting that automatically connects to the male connector of the suction duct of the patient interface holder, when the second positioning device of the patient interface is coupled within the holding device of the patient interface holder, to form a fluid path therethrough, and
the fluid path fluidically couples the suction duct to a suction opening of the patient interface in a region of the first positioning device, to hold the first positioning device in abutment on the patient's eye by a relative negative pressure generated by means of the suction device.
