Likely contamination of a surgeon's conjunctiva by patients' body fluids is surprisingly frequent. Blood and fat are the most common agents but cellular implantation may occur. Possible contamination was documented in 37 of 60 orthopedic procedures. Power tools, hammering and the use of rongeurs are the main culprits in producing a forced spray most likely to cause contamination. Reduction of the hip at the time of replacement arthroplasty is often associated with propulsion of blood. Not a single case of possible contamination resulted from the pumping action of a severed vessel. Since orthopedic surgeons work in a high-risk environment, safety glasses are recommended to prevent contraction of viral diseases such as hepatitis B and acquired immune deficiency syndrome by way of the conjunctiva. The glasses will also protect the surgeon from bacterial and cellular conjunctival contamination, in addition to preventing physical damage secondary to propelled bone and cement.
外科医生的结膜很可能被患者体液污染，这种情况出奇地频繁。血液和脂肪是最常见的污染物，但也可能发生细胞植入。在60例骨科手术中，有37例记录了可能的污染情况。电动工具、锤击和使用咬骨钳是产生最有可能导致污染的强力喷雾的主要原因。置换关节成形术时髋关节复位常伴有血液推进。没有一例可能的污染是由切断血管的泵吸作用导致的。由于骨科医生在高风险环境中工作，建议佩戴安全眼镜，以防止通过结膜感染乙型肝炎和获得性免疫缺陷综合征等病毒性疾病。除了防止被推进的骨头和骨水泥造成身体损伤外，眼镜还能保护外科医生免受细菌和细胞性结膜污染。
