METHOD FOR LASER CATARACTOUS EXTRACTION Russian patent published in 2005 - IPC

FIELD: medicine, ophthalmosurgery.

SUBSTANCE: the present innovation deals with surgical treatment of cataract at different degrees of density. One should form two mutually perpendicular diametral grooves at the surface of lenticular nucleus, followed by nucleus' breaking, fragmentation and aspirating. On breaking the nucleus one should form a crater in the center of nucleus to decrease each nuclear fragment twice. One should perform aspiration of each fragment successively. While forming perpendicular grooves and a crater it is necessary to apply laser radiation at energy of 150-200 mJ, and while breaking each fragment of lenticular nucleus one should decrease radiation energy up to 100 mJ. The method enables to shorten time for laser impact and total duration of operation, and, also, to conduct operation upon eyes with narrow pupils and apply capsulorhexis of lower diameter, as well.

EFFECT: decreased traumatism of operation performed.
