Abstract
An apparatus for laser surgery, particularly of the cornea is provided. Through this apparatus, a laser, especially a UV-laser, can be imaged on the tissue undergoing the operation. A diaphragm is arranged in the optical path of the laser and defines the illuminated region of the tissue. The diaphragm includes a slit which has a fixed angular alignment and an adjustable length and width. Further, an optical rotary device is provided which rotates the beam about an optical axis in between the slit and the tissue undergoing the operation.
