Laser ophthalmological unit

Claim 1

A laser ophthalmological unit comprising a laser producing a powerful light emission in order to exert the action upon the patient's eye; an optical system for supplying and focusing the laser emission to a specified point of the patient's eye; an optical system for illumination of the surgery field, comprising a slit source provided with a light-transmitting element with a marker for guiding the laser beam to a specified point of said patient's eye; an optical deflecting element for directing the slit source beam to the patient's eye; a casing wherein said lasing source and said slit illumination source are housed and rigidily secured together, the optical elements of the system for supplying the powerful laser beam and said deflecting optical element mounted outside said casing are rigidly secured to said casing but can be moved for alignment so that optical axes of both systems can coincide in a specified point where the patient's eye is located; a microscope having an axis of rotation for observation of the surgery field; a hinge securing said casing for rotation around the axis of rotation of the microscope, which lies in the focal plane of both said systems and the microscope, and as a result irrespective of the angle between the optical axes of said microscope and said slit illumination source, the marker is always in the focal plance of said microscope.
