Is Ocular Safety in Orthopedics Overlooked? A Systematic Review of Annual Ocular Radiation Exposure and Protective Measures
Across 23 dosimetry studies, most orthopaedic surgeons' eye doses were below the 20 mSv annual limit, though high-volume fluoroscopy users may exceed it. Wrap-around leaded glasses cut eye dose about…
