最近注意力已经转向用于对眼压计进行消毒以消除在眼泪中发现的人类免疫缺陷病毒和其他病毒的适当方法。 非接触式眼压计，利用压缩空气的短暂脉冲，是一种替代方案，避免了消毒程序的需要。 我们使用与美国光学非接触式II眼压计（剑桥仪器公司，剑桥，马萨诸塞州）或Keeler Pulsair眼压计（Keeler仪器公司，Broomall，宾夕法尼亚州）电耦合的照相机和闪光灯，在眼压测量期间拍摄角膜轮廓。 大多数眼睛显示一定程度的泪膜裂开和微气溶胶形成。 虽然眼泪还没有被认为是人类免疫缺陷病毒感染的来源，但可能被人类免疫缺陷病毒和其他病毒污染的液滴很容易被分散，这是令人不安的。 “空气抽吸”眼压测量可能不是如先前假定的无菌的。
Attention has been directed recently to appropriate methods for sterilizing tonometers to inactivate the human immunodeficiency virus and other viruses that have been found in tears. Noncontact tonometry, utilizing a brief pulse of pressurized air, is an alternative that avoids the need for sterilization procedures. We used a camera and flash electrically coupled to an American Optical Non-Contact II tonometer (Cambridge Instruments Inc, Cambridge, Mass) or a Keeler Pulsair tonometer (Keeler Instruments Inc, Broomall, Pa) to photograph the corneal profile during tonometry. Most eyes revealed some degree of tear film dehiscence and microaerosol formation. While tears have not been implicated as a source of human immunodeficiency virus infection, the ease with which droplets, potentially contaminated with human immunodeficiency virus and other viruses, are dispersed is disturbing. "Air-puff" tonometry may not be aseptic as previously presumed.
