This paper present a tonometer incorporated in a contact lens, which allows simultaneous measurement of intraocular pressure and performance ophthalmoscopy. The tonometer can record the pulse curve continuously, which can give us an indication of any circulatory problem. The device is therefore expected to yield additional information useful for the diagnosis of early glaucoma. Te device has three force sensors built in, which allow continuous measurement of the force exerted on the eye surface by the contact lens. The force of the contact lens on the eye can be altered and makes the adjustment of different eye pressures possible. These induced changes of the eye pressure and their influence on the fundus can be checked. We have taken some measurements on enucleated human eyes to compare our device with a Statham tansducer in the vitreous. We found a good correlation. We are currently taking measurements in volunteers. The clinical relevance of these observations and measurements will be examined in a future study.
本文介绍了一种集成在隐形眼镜中的眼压计，它能够同时测量眼压并进行眼底镜检查。该眼压计可以连续记录脉搏曲线，这能为我们提供任何循环系统问题的迹象。因此，该设备有望产生有助于早期青光眼诊断的额外信息。该设备内置了三个力传感器，可连续测量隐形眼镜施加在眼表面的力。隐形眼镜对眼睛的作用力可以改变，从而能够调节不同的眼压。可以检查这些眼压的诱发变化及其对眼底的影响。我们对摘除的人眼进行了一些测量，以便将我们的设备与玻璃体内的Statham换能器进行比较。我们发现两者有很好的相关性。我们目前正在对志愿者进行测量。这些观察和测量的临床相关性将在未来的研究中进行检验。
