Abstract

The use of laser radiation for endoscopic surgery has been a significant advance in patient care. The usual modality is to use an optical fiber to deliver the light energy from the laser to the patient. However, there have been a number of incidents of the optical fiber breaking while the beam was active. Although no injuries have been reported, we investigated the hazard posed by such broken fibers to operating room (OR) personnel. Optical fibers were fractured in a manner that simulated the fractures in the ORs and the output power and divergence measured. In most cases, the laser emission was still `beam-like,' presenting a potential ocular hazard. Clearly proper use of eye protection and administrative controls are needed to avoid injuries.
