METHOD FOR BIENERGETIC FRAGMENTATION OF NUCLEUS OF CRYSTALLINE LENS Russian patent published in 2015 - IPC A61F9/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ophthalmic surgery, and can be used for bienergetic fragmentation of a nucleus of crystalline lens. That is ensured by forming a tunnel approach and a corneal paracentesis. Viscoelastic is introduced. That is followed by performing a capsulorrhexis. The nucleus of crystalline lens is disintegrated by the combined exposure to Nd-YAG laser energy at wave length 1.44 mcm and ultrasound. A cortical layer of the crystalline lens is first disintegrated on the limited site. That is followed by forming a recess and exposing the most solid nucleus structure to laser light with preserving the cortical layer at the given stage of the operation. That is combined with disintegrating and aspirating all lens structures by means of an ultrasonic tip.

EFFECT: method enables minimising eye tissue injuries by fragmenting the nucleus of the crystalline lens covered with the cortical layer, as well as reducing the laser exposure while disintegrating the most solid nuclei with creating the minimum-size tunnel approach and using the ultrasonic needle with a lower-size cuff.
