摘要： A process and device for shaping surfaces, in particular lenses, by laser machining of the surfaces, are preferably used for photorefractive ceratectomy and for shaping ophthalmologically exact contact lenses. In order to ensure an at least acceptable partial correction of the surface to be machined after a sudden interruption of the surface machining process, the device has a scanning pulsed laser (1), a beam shaping unit (2) and a laser beam deflecting unit (3) which deflects the laser beam onto a surface (4) to be machined. The laser beam deflecting unit (3) and the beam shaping unit (2) can be controlled by a controlling unit (5) with co-operating first (6) and second (7) input units, a computing unit (8) to which the data from the first and second input units (6; 7) are supplied, a block generator (9) to which the data from the computing unit (8) are supplied and in which the individual laser machining co-ordinates for removing any predetermined individual layer of the surface are mutually associated, and a sequence generator (10) to which the data generated by the block generator (9), gathered into blocks which correspond to an individual machining zone, are supplied, and which orders the individual blocks into a predetermined sequence. A particular block sequence transmitted by the sequence generator (10) acts upon the laser beam deflecting unit (3) and beam shaping unit (2) in such a way that a complete partial correction of the surface (4) to be machined is ensured for each block sequence. Also provided is a central processing unit (11) which co-ordinates in a predetermined manner the switching and control of at least the laser unit (1), the beam shaping unit (2; 21) and the laser beam deflecting unit (3) depending on the control data from the control unit (5).

摘要： A medical apparatus for treating the eyes comprises a slit lamp and a laser which generates a treatment beam which can be directed into the patient's eye, together with the illumination beam generated by the slit lamp, by means of an optical deflecting element. The apparatus also comprises a device for observing the eye and an adjustment device which can be actuated by an actuating element in order to adjust the position of the appliance relative to the eye. The optical deflecting element is driven so as to swivel about two mutually perpendicular axes. In order to simplify the actuation of the drive which swivels the optical deflecting element, a ball mounted in a freely rotatable manner on the apparatus is in frictional contact with the drive shafts of two angular momentum generators mounted perpendicular to each other on the apparatus. Each angular momentum generator controls the swivelling of the optical deflecting element about one axis.

摘要： An apparatus for examining and treating the eye comprises an observation device (6) which is directed into the patient's eye (9), a lamp and a laser which direct radiation, via an optical deflection device (12), into the eye in order to illuminate and treat the eye. To ensure rapid and precise displacement of the irradiated region of the eye, the optical deflection device is designed as an electrically controlled scanner system (11 ... 19) with deflection along two mutually perpendicular axes.

摘要： In order, in a device for modelling or correcting optical lenses, especially the cornea of the eye, with a pulsed laser, the radiation pulses of which are directed via optical imaging means and shutters on the surface of the lens to be modelled in such a way that concentric circular areas on the lens surface are affected by a differing number of radiation pulses and are thus removed at different depths, to achieve a precise dosing of the number of radiation pulses over the entire area to be treated and to ensure the accurate bordering of the irradiated areas, it is proposed that a mask rotatable about an axis perpendicular to the lens surface and fixed with respect to the lens is fitted on the lens which has several radial mutually concentric recesses in the peripheral direction, the length of which differs in the peripheral direction, a drive system rotates the mask stepwise and a control for the drive system and the laser is fitted which fires the laser after the mask has been further rotated and while it is stationary.
