What type of injury is possible with Class IIIB lasers?

Class IIIB lasers, which operate within a certain power range, are significant in terms of their potential biological effects, particularly regarding eye safety. The correct answer points to a common eye injury as a notable risk associated with the use of these lasers. When directed toward the eye, Class IIIB lasers can cause damage to the retina, leading to visual impairment or even permanent injury. This ability to inflict harm is due to the wavelength and power output, which can penetrate the eye and damage sensitive tissues.

While severe skin burns, minor skin irritation, and severe respiratory problems can be associated with other types of lasers or hazardous materials, they are not the primary concerns in the context of Class IIIB lasers. The specific capabilities of these lasers mean that the risk of eye injury is significantly heightened, necessitating stringent safety precautions, such as protective eyewear for both operators and bystanders during procedures.
