There is a continuous process of development of new tonometer types following different measurement principles. The impedance measurement method, using the elasticity of the eyeball, allows tonometry even through the eyelid. Two new tonometers based on the impedance principle were investigated by clinical comparison measurements according to the international standard for human eye tonometers ( ISO 8612). The tested tonometers determine the intraocular pressure without topical anaesthesia. The different elastic properties of an individual eyelid and also the different elastic properties of the human eye due to a large variation in rigidity cause serious problems for these measurements. Statistical properties of the two investigated tonometers are presented and discussed. Statements and conclusions about the medical application of these measurement devices for ophthalmologists are made.
新型眼压计不断涌现，遵循不同的测量原理持续发展。阻抗测量法利用眼球弹性，甚至可隔着眼睑进行眼压测量。根据国际人眼眼压计标准（ISO 8612），通过临床对比测量对两款基于阻抗原理的新型眼压计进行了研究。受试眼压计无需局部麻醉即可测定眼压。个体眼睑弹性各异，且由于硬度差异极大，人眼弹性也各不相同，这给这些测量带来了严重问题。文中给出并讨论了两款受试眼压计的统计特性。针对眼科医生就这些测量设备的医学应用给出了说明和结论。
