摘要： In an instrument for the examination and surgery of the eye, an ophthalmological objective is combined with an operation microscope whose main objective is combined with an optical system of variable back focus and focal length. Every plane of the eye lying between the cornea and the fundus is imaged by the instrument at an intermediate image plane. In this way, with a single instrument, the operator can carry out work on the cornea, the eye lens, the vitreous body, and the retina. Since the instrument provides the observer with a reflection-free image, contact of the eye to be operated upon with an optical auxiliary means which eliminates the refractive power is unnecessary.

摘要： An Nd:YAG laser of small size with a passive quality switch is combined with a slit-lamp instrument, to form an ophthalmological combination instrument for diagnosis and treatment. By a plurality of pulses within a pulse train, which succeed each other within the .mu. sec range, particularly good therapeutic effects are obtained. A second laser, emitting continuous visible radiation, has its beam aligned with the beam of invisible radiation from the first laser, and shows the user at all times the location of the beam of invisible radiation. The visible beam of radiation is split into two beams separated from each other by a light-free zone, and there is provision for blocking and unblocking these two beams alternately, which produces an effect which greatly aids the user in accurate focusing. This combination instrument affords the user the possibility of making a diagnosis and following it immediately by treatment.

摘要： The invention contemplates an operation microscope in which three-dimensional viewing adjustment is possible with respect to an object (8) to be observed, all without forcing the surgeon or any co-observing person or instrumentality to move. To this end, the exit pupils and thus all viewing windows are positionally invariant, i.e., they are stationary and therefore can be securely related to a microscope support (5). An objective housing (7) in front of the microscope housing (1) is associated with all viewing systems (2, 3, 4), and this objective housing contains an objective of variable back focus as well as optical components (11, 12) for selective deflection of the observation ray path in each of two polar-coordinate directions. In making any one or all of the three-dimensional viewing adjustments, only elements of relatively low mass within the objective housing (7) need be moved.

摘要： For defined positioning of a laser beam in an ophthalmological instrument with a slit projection device and an optical observation unit, a focusing objective is displaced by a displacement device in a plane parallel to the observation beam path of the optical observation unit. The laser beam path and the slit projection beam path are separately deflected coaxially with the observation beam path in the direction of the target plane. Defined positioning of a laser beam in the patient's eye is achieved by means of the displacement device, which includes a displacement element connected to the focusing objective, and an operating element. The displacement device furthermore offers diverse means of adjustment.
