The invention as a lamp base 32 is implemented to be movable or to be mounted on a wall or a ceiling, at least in part, by a manually adjustable stand arm arrangement, which may be the stand base (34, 36) has a stand (24 ), and it proposes a device for eye surgery comprising a surgical microscope 38 attached to the stand arm arrangement. In addition, the eye surgical unit comprises a laser device that provides a pulse and focusing the laser radiation has a radiation characteristic for applying incision in the human eye (14). The laser device comprises a laser source 20, a laser treatment head is attached to the stand arm arrangement (34, 36) and emitting a laser radiation (26), the laser treatment, and flexible head provided for the purpose of transmission of the laser radiation It includes a transfer arm transmission fiber (22) or a combination beam. The laser treatment head 26 provides the observation beam path (52) can be located or positioned in the observation beam path and the observation beam path of a surgical microscope according to (38). According to one embodiment, the laser treatment head 26 can be moved from the use position to the non-use position, in the use position, the laser treatment head is located above and below the operation microscope 38 in the eye 14, In the non-use position spaced apart from the working range of the surgeon 40, the surgeon is observed through a microscope, it can be seen directly to the eye (14) to be treated.
