In 1994, under the direction of an academician S.N. Fedorov was first developed a method of laser cataract extraction (LCE) on the basis of a YAG laser of 1.44 microns, that does not require ultrasound. This paper presents an analysis ofa new microinvasive technology (mLEK) with the combined impact of endodissector Nd-YAG 1.44 microns and biostimulating low-intensity helium-neon laser radiation of 0.63 micron, activating the regenerative processes. Two types of radiation are delivered to the eye cavity by one waveguide. Three groups had 528 operations: 148 operations at a new technology (mLEK) in comparison with the main methodology LEK (176 operations) and ultrasonic microinvasive phacoemulsification (mFEC — 204 operations). With mLEK 1.5 times decreased flow of irrigation solution. The loss of cells of the rear corneal epithelial (RCE) in the main group is 2 times less than in mFEK group. The efficiency of the laser energy is 2 times higher as compared with the ultrasound, IOP rise is 2 times less. Echobiometrical picture of ciliary body thickness returned to the original settings within 15-18 days of mLEK, within 20-25 days of LEC and within 80-90 days of mFEK. In the long-term period of 1 year after mLEK have been noted fewer complications (5.4%) in comparison with mFEK (10.3%) and significantly lower in comparison with the basic operation of LEK (6.3%). New mLEK technology reduces energy consumption, the volume of irrigation, the level of induced astigmatism, loss of ZAR cells, accelerating the timing of rehabilitation.

Key words: microinvasive laser cataract extraction, 1.44 μm Nd-YAG laser, 0.63 μm He-Ne laser, intraoperative biostimulation, phacoemulsification.
