Laser surgery

Definition

Laser surgery is a medical procedure that uses focused light beams from lasers to cut, burn, or destroy tissue for therapeutic purposes. This technique offers precision and minimal damage to surrounding tissues, making it ideal for various applications, including eye surgeries and dermatological treatments. Different types of lasers are utilized in this practice, each with unique properties suited for specific surgical tasks.
