METHOD FOR REMOVING SOLID NUCLEUS LENS FROM VITREOUS BODY BY APPLYING ULTRASOUND Russian patent published in 2006 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: method involves making incisions in flat portion of vitreous body and subtotal vitrectomy. Traditional illuminator is changed for lance illuminator after vitrectomy. Directing the lens with the lance, notch is made in capsule sack in equatorial zone with vitreotome. Then, illuminator lance is placed into the formed notch and the lens is stringed on the lance by means of vitreotome tip to a depth of 1/2-2/3 of lens diameter. The lance is arranged in lens equator plane and the whole lens is positioned in the central zone of the vitreous body cavity. The capsule sack and cortical layers are cut off with vitreotome retaining the nucleus on the lance. The vitreotome is changed for cannula for delivering perfluororganic compound to optic nerve disk in the amount of 1/5-1/4 of vitreous body cavity. The cannula is withdrawn and retinal blade is introduced into the vitreous body cavity. The nucleus is turned with one of its poles towards the blade by rotating the lance. When retained in this position in the central zone of the vitreous body cavity, the nucleus is fragmented in moving with the blade from down to top along the nucleus. The fragments are 2-4 mm thick. Cuttings are made in turn on one and on the other side relative to the lance. The blade is changed for ultrasonic phacoemulsifier nozzle applied for catching nucleus fragments in turn from perfluororganic compound surface and moving them to anterior parts of the vitreous body cavity and removing. The perfluororganic compound is substituted for salt solution.

EFFECT: enhanced effectiveness of treatment; reduced risk of traumatic complications.
