Standardized guidelines that are clinically practical are needed to assist the prescriber in minimizing the risk of conveying infection through multiuse diagnostic contact lens use and reuse.Contact lens prescribers face the specter of transferring potential pathogens from one patient to another when reusing diagnostic (trial) contact lenses on multiple patients because infectious organisms have been recovered from worn contact lenses, although there is no evidence of transmission through this mechanism. These pathogens can be introduced into the system from one patient to another, or they may be introduced by clinician lens handling, storage, or both. These pathogens can cause acute or chronic systemic or ocular infection that can lead to significant morbidity (temporary or permanent) that includes vision loss.
需要制定临床实用的标准化指南，以帮助医生尽量降低通过重复使用多用途诊断接触镜传播感染的风险。当在多名患者身上重复使用诊断（试用）接触镜时，接触镜开方者会面临将潜在病原体从一名患者转移到另一名患者的风险，因为已经从佩戴过的接触镜中回收了传染性生物体，尽管没有通过这种机制传播的证据。这些病原体可能会从一名患者传播到另一名患者，或者可能会通过临床医生的镜片处理、储存或两者兼而有之引入系统。这些病原体可能会引起急性或慢性全身性或眼部感染，从而导致严重的发病率（暂时性或永久性），包括视力丧失。
