APPA YAG LASER 307

The APPA 307 is an ophthalmic Nd:Yag laser, for the treatment of secondary cataract and wide-angle glaucoma. The laser is integrated into a 5-magnification Zeiss type slit lamp. Focusing is done with a Dual Beam target beam system. It has output energy adjustable from 0.2mj to 10mj, as well as double or triple pulse capability. The beam focus can be shifted ±500 µm posterior or anterior to the target. With an ergonomic and specially designed table with electric height adjustment. Includes iridectomy-capsulotomy lens.
