The laser photolysis system works on the principle devised by Dr. Jack Dodick of Manhatten Eye, Ear & Throat Hospital New York, USA. A Q-switched Nd:YAG laseris channeled through a quartz fibre. The fibre is inserted into an aspirating handpiece. The fibre terminates approximately 1.3mm in front of a titanium target, which is at the focal point of the laser beam. When the laser pulses strike the target, disruptive energy is created in the form of shock waves because og optical breakdown in the titanium target & resulting plasma formation. These shock waves have sufficient strength to fragment(lyse) the nucleus. There is no direct exposure of laser inside.

There is no clinicaly significant temperature rise & it needs significantly lower acoustic energy to disrupt the cataract tissue. The time required for the procedure is comparable to the ultrasound phacoemulsification.
The bimanual probe construction houses laser & aspiration in one probe & irrigation in the other probe.
