METHOD FOR MICROINVASIVE PHACOEMULSIFICATION Russian patent published in 2015 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: tunnel approach and corneal paracentesis are formed. Introducing viscoelastic is followed by performing capsulorhexis, hydrodissection and hydrodelineation. An ultrasonic needle with an irrigation cuff is inserted through a tunnel incision into an eye cavity; an accessory irrigation instrument is inserted through the corneal paracentesis inclined to the tunnel incision. Fluid supply into an anterior eye chamber from an irrigation main line through a coaxial canal of the phaco needle and the accessory irrigation instrument simultaneously is actuated A nucleus of crystalline lens is destructed, and the crystalline mass are removed through an aspiration canal of the phaco needle simultaneously with the irrigation fluid.

EFFECT: by performing the primary energy-saturated stages using the two separately managed and mutually by-pass flows of the irrigation fluid, the method allows using the microinvasive approaches that reduces intraoperative injuries, increases controllability of the manipulations.
