Despite documented cases of infectious disease transmission to medical staff via conjunctival contamination and widespread recommendation of protective eyewear use during surgical procedures, a large number of surgeons rely on their prescription spectacles as sole eye protection. Modern fashion spectacles, being of increasingly slim design, may no longer be adequate in this role.
A survey was conducted among the surgeons at Waikato Hospital from December 7, 2004 to February 1, 2005, to assess current operating theater eyewear practices and attitudes. Those who wore prescription spectacles were asked to assume a standardized "operating position" from which anatomic measurements were obtained. These data were mathematically analyzed to determine the degree of palebral fissure protection conferred by their spectacles.
Of 71 surgical practitioners surveyed, 45.1% required prescription lenses for operating, the mean spectacle age being 2.45 years; 84.5% had experienced prior periorbital blood splashes; 2.8% had previously contracted an illness attributed to such an event; 78.8% participants routinely used eye protection, but of the 27 requiring spectacles, 68.0% used these as their sole eye protection. Chief complaints about safety glasses and facial shields were of fogging, poor comfort, inability to wear spectacles underneath, and unavailability. Our model predicted that 100%, 92.6%, 77.8%, and 0% of our population were protected by their spectacles laterally, medially, inferiorly, and superiorly, respectively.
Prescription spectacles of contemporary styling do not provide adequate protection against conjunctival blood splash injuries. Our model predicts the design adequacy of currently available purpose-designed protective eyewear, which should be used routinely.
尽管有记录表明传染病可通过结膜污染传播给医务人员，并且广泛推荐在外科手术过程中使用防护眼镜，但仍有大量外科医生仅依靠他们的处方眼镜作为眼部防护。现代时尚眼镜的设计越来越轻薄，可能不再足以胜任这一角色。
2004年12月7日至2005年2月1日期间，对怀卡托医院的外科医生进行了一项调查，以评估当前手术室眼镜的使用情况和态度。要求佩戴处方眼镜的医生摆出标准化的“手术姿势”，并获取解剖学测量数据。对这些数据进行数学分析，以确定他们的眼镜对睑裂的保护程度。
在接受调查的71名外科医生中，45.1%的人手术时需要佩戴处方眼镜，眼镜的平均使用年限为2.45年；84.5%的人曾有过眶周血液飞溅的经历；2.8%的人曾因这类事件感染疾病；78.8%的参与者经常使用眼部防护用品，但在27名需要佩戴眼镜的人中，68.0%的人仅将眼镜作为眼部防护用品。对安全眼镜和面罩的主要抱怨包括起雾、舒适性差、无法在下面佩戴眼镜以及难以获得。我们的模型预测，我们研究对象中分别有100%、92.6%、77.8%和0%的人在外侧、内侧、下方和上方受到眼镜的保护。
现代款式的处方眼镜不能提供足够的防护以避免结膜血液飞溅伤。我们的模型预测了目前市售的专用防护眼镜的设计适用性，应常规使用此类眼镜。
