A laser therapy instrument:

• wherein the laser therapy instrument is structured for surgery on a cornea, a sclera, a vitreous body or a crystalline lens, and is usable alternately with other instruments for eye diagnosis or eye therapy, in a common treatment area in which a patient or a patient's eye is positioned, the common treatment area being accessible to the laser therapy instrument and the other instruments in succession,
• the laser therapy instrument comprising:
• a beam conducting device including an exit lens system that conducts a therapeutic laser beam to the common treatment area, and
• a device operably coupled to the beam conducting device that moves at least a part of the beam conducting device that includes the exit lens system, into the common treatment area prior to use of the laser therapy instrument and out of the treatment area after the use of the laser therapy instrument, such that
• the treatment area, after at least the part of the beam conducting device including the exit lens system has been moved out of the treatment area, is freely accessible for using the other instruments;
• the beam conducting device that can be moved in and out comprising a laser arm, wherein the exit lens system included in the laser arm, proceeding from its working position at the eye, is either swiveled out of the treatment area by an angle of approximately 90 degrees along a circular arc path or moved out of the treatment area along a straight line and a circular arc path;
• wherein the laser arm, when swivelled out of the treatment area, is located within an outer contour of the laser therapy instrument;
• and
• wherein the laser arm is adjustable in all three spatial directions X, Y and Z.
