ABSTRACT

Erbium:yttrium-aluminum-garnet (Er:YAG) cataract extraction has shown considerable promise as a new technique for lens nucleus removal prior to intraocular lens (IOL) implantation for the treatment of cataracts. Recent studies suggest that the laser energy is dissipated much more locally and heats surrounding intraocular tissues less than traditional ultrasonic phacoemulsification does. Clinical studies demonstrate the safety of the procedure in human cataract patients, and a randomized study found little difference in outcomes when compared to conventional cataract surgery. Further advances in fiber optic delivery systems and handpiece development may make this approach even more attractive in the future.
