The YAG Laser (307), specifically the Appasamy APPA-307, is an ophthalmic medical device that integrates an Nd:YAG photodisruptor with a slit lamp, used primarily for posterior capsulotomy (treating cloudy membranes after cataract surgery) and creating iridotomies for glaucoma, offering precise, low-energy treatments with a super Gaussian beam for clear vision and patient comfort, featuring compact design, advanced focusing, and robust performance for various anterior and posterior eye conditions.
