A new technique of energy cataract surgery with the simultaneous use of two wavelength of laser emission acting as high-intensity laser-endodissector (Nd:YAG, wavelength λ = 1.44 µm) and a low-intensity laser-endobiostimulator (He-Ne, wavelength λ = 0.632 μm) is represented. The surgical technique is bimanual. The radiation of highintensity laser ensures the destruction of cataract lens of any density level without additional assistance of ultrasound and without manual fragmentation. The laser tip, which contacts the eye tissues, does not heat up. In the process of high-intensity laser action splitting and spalling of the eye lens core occurs. Laser energy does not go beyond the lens capsule as it is almost completely absorbed by the liquid of the anterior chamber (water) at less than 1 mm from the distal end of the laser tip. Simultaneous exposure to radiation of high-intensity and low-intensity lasers delivered to the eye lens via one laser tip provide to prevent the progression of posttraumatic inflammatory process in the eye at the initial stage of the start of pathophysiological intracellular changes. This ensures high efficiency and safety of simultaneous dual-wavelength laser cataract extraction (DW LCE).
