Abstract
THE INVENTION RELATES TO MEDICINE, I.E., TO OPHTHALMOLOGY: A DEVICE FOR SURGICAL TREATMENT OF AMETROPIA COMPRISES A UV PULSED LASER (1) AND A DISTRIBUTOR (3) OF RADIATION ENERGY DENSITY OVER THE BEAM CROSS-SECTIONAL AREA, THE ABOVE DISTRIBUTOR BEING PLACED ACROSS THE PATH OF THE LASER RADIATION BEAM. ACCORDING TO THE INVENTION, THE DISTRIBUTOR (3) IS AN OPTICAL SYSTEM, COMPRISING ARRANGED ON A COMMON OPTICAL AXIS TWO TAPER LENSES (5,6) AND A TELESCOPIC OBJECTIVE (7) AND CAPABLE OF TRANSFORMING A PARALLEL CYLINDRICAL BEAM (2) OF RADIATION EMITTED BY THE LASER (1), INTO A VARIABLE-DIAMETER ANNULAR BEAM (20), THE MAXIMUM VALUE OF THE BEAM DIAMETER BEING COMPARABLE WITH THE DIAMETER OF A PATIENT'S CORNEA (4).(FIG 1)
