yttrium-aluminum-garnet laser

Abbreviation: YAG laser
A laser with a crystal made of yttrium, aluminum, and garnet, used for skin resurfacing, or tissue penetration in oral, urological, ophthalmic, cardiac, orthopedic applications. The depth of the penetration of the laser energy, its tissue absorption, and tissue-sparing characteristics vary with the materials used as additives to the crystal, e.g., erbium, holmium, or neodymium.

Patient care

Care involves general support, giving explanations, and answering questions. All equipment must be checked and all rules observed. The nurse assists the surgeon as necessary.
