title: [Crystotomy with use of surgical ultrasonic instruments].
abstract: The authors propose to make crystotomy using energy of low-frequency ultrasound (the device URSK 7N 22, frequency - 26.5-30 kHz, amplitude - 40-50 mcm). The working part of the waveguide was designed in specific geometric shape. Indications to ultrasonic crystotomy and surgical techniques are outlined. A total of 29 patients were operated on. Good results were achieved in 25 patients, satisfactory results in 4 patients.
