The investigations of used pulsed Q-switched neodymium:YAG laser induced plasma and shock wave during experimental lenses emulsification were presented. The formation and propagation of plasma and shock wave created by the high powered Nd:YAG laser pulses with a titanium target were imaged through optical multiple analysis, and the pressure of shock wave was calculated. The results of shock wave interacting with the lenses material were observed. The lenses, simulated at different hardness, were placed in containers filled with Ringer's solution. The experimental results are promising and show that the Nd:YAG laser can be used for human lens emulsification.
