Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, specifically to ophthalmology. For microinvasive transscleral fixation of a dislocated posterior chamber intraocular lens, cornea paracenteses and conjunctival flaps are formed in a projection of haptic elements of the intraocular lens (IOL). Fixation of IOL is performed by means of a straight suture needle with polypropylene loop 10/0. For this purpose, a suture loop is introduced through the corneal paracentesis; using a manipulator, a suture loop is brought over the IOL haptic element on the opposite side; hollow guide needle 27G is transxleral introduced in 2-2.5 mm from the limb, wherein the suture loop is grasped and brought under the haptic element; suture needle is inserted into the lumen of the guide needle and brought out, thereby forming a "cow hitch" directly on the haptic IOL. Similar manipulations are performed with the opposite haptic element. IOL is centered relative to pupil plane. IOL is fixed to the sclera by applying a Z-shaped suture, the ends of which are immersed under the conjunctival flaps. 
     EFFECT: method provides stable clinical effect and minimal risk of intra- and postoperative complications ensured by complete control of intraoperative manipulations.

In this case, the voltage of the constant voltage source U source  is 10-40% of the voltage of the charger U charge  , inductive energy storage devices of both the first and second circuits are connected in series to a drift diode, which is configured to break the reverse current at the time when the total charge Q diode  passed through it is determined by the expression Q diode  = ∫Idiode * dt = 0, where t is the operating cycle time of the drift diode from 0 to t 3 ; Q diode  - charge passed through the drift diode; I diode  - current through the drift diode; t 3  is the moment of breakage of the reverse current through the drift diode. Moreover, a constant voltage source, a capacitive energy storage of the second circuit and a drift diode are connected to a common bus at the second output.  
     EFFECT: technical result of the proposed solution is to increase the repetition rate of the output pulses due to the absence of residual currents in the drift diode with a sharp recovery of the non-conducting state after the end of the operating cycle.
