What protective measures should be followed when lasers are used in the OR?

• A. Wear no eye protection
• B. Wear appropriate eye protection, use non-reflective surfaces, and ensure proper smoke evacuation
• C. Allow reflective surfaces near the beam
• D. Ignore smoke evacuation

Answer: (B)

When lasers are used in the OR, protecting the eyes, reducing reflections, and managing laser plume are essential safety steps. Eye protection must be appropriate for the specific laser’s wavelength and power, and worn by all personnel who could be exposed to the beam, because even brief exposure can cause serious eye injury. Minimizing reflective surfaces is important because a reflected beam can travel unpredictably and injure someone or ignite materials; using non-reflective, matte finishes on instruments, drapes, and surrounding surfaces and arranging equipment to keep the beam path controlled reduces this risk. Smoke evacuation is also critical because laser plume contains fine particulates and potentially toxic gases; a proper smoke evacuator near the surgical field helps protect staff from inhalation exposure and maintains visibility for the surgeon. Together, these measures create a safer laser environment in the OR.
