Medical lasers have been widely used for various diseases. Despite the notable benefits, lasers could cause several complications, such as skin burn, eye injury, airway fire, and so on. These accidents may occur not only with patients, users of the laser, or laser handlers, but also to people passing in front of the laser treatment room. Although there is a risk associated with the laser, most of them can be prevented through good training, the use of proper protection equipment, and ensuring the safe operation of the laser at all times. Due to the increasing use of lasers and the growing interest in their use, medical institutions should particularly emphasize the safe use of lasers and introduce systems for laser safety.
