Laser peripheral iridectomy comparing Q-switched neodymium YAG with argon.

Twenty-five patients who required bilateral peripheral iridectomies had the right eye treated by the Nd YAG laser and the left eye by the pulsed argon laser. The photodisruption of iris tissued produced by the Nd YAG produces a quicker more efficient iridectomy than the thermal effect of the argon laser with less tendency to healing and inflammation. We conclude that Neodymium YAG laser iridectomy is a safe effective alternative to argon laser iridectomy with no increase in complications during the follow up period and is preferred by the patients.
