Since the advent of phacoemulsification, alternative technologies have been developed to facilitate cataract extraction. The first laser system, the Dodick Photolysis system, a Q-switched Nd:YAG laser system (A.R.C. Laser Corp), was approved by the US Food and Drug Administration (FDA) in 2000. This system generates laser shock waves at 200–400 ns that strike a titanium target at the end of the aspirating handpiece, thereby breaking up the lens nucleus.
