The Pollack Iridotomy-Gonio Laser Lens has two coated glass buttons on the anterior surface that enable performance of iridotomy and gonioscopy without changing lenses and with minimal refocusing of the slit lamp. It is designed to easily determine if the angle has been opened following iridotomy. The 1.5x magnification button allows lower levels of energy to be employed during the procedure. Also suitable for Argon Laser Trabeculoplasty (ALT). Image mag is 1.5x for both iris and anterior chamber angle.
