    • A tonometer system for measuring intraocular pressure by accurately providing a predetermined amount of applanation to the cornea and detecting the amount of force required to achieve the predetermined amount of applanation. The system is also capable of measuring intraocular pressure by indenting the cornea using a predetermined force applied using an indenting element and detecting the distance the indenting element moves into the cornea when the predetermined force is applied, the distance being inversely proportional to intraocular pressure. Also provided is a method of using the tonometer system to measure hydrodynamic characteristics of the eye, especially outflow facility. The tonometer system includes a contact device for placement in contact with the cornea and an actuation apparatus for actuating the contact device so that a portion thereof projects inwardly against the cornea to provide a predetermined amount of applanation. The system further includes a detecting arrangement for detecting when the predetermined amount of applanation has been achieved and a calculation unit responsive to the detecting arrangement for determining intraocular pressure based on the amount of force the contact device must apply against the cornea in order to achieve the predetermined amount of applanation. An indentation distance detection arrangement is also provided for use when intraocular pressure is to be detected by indentation. In carrying out the method, the system is used to detect intraocular pressure between successive steps of forcing intraocular fluid out from the eye.
    • 一种用于通过准确地向角膜提供预定量的压平来测量眼压并且检测达到预定量的压平所需的力量的眼压计系统。 该系统还能够通过利用使用压印元件施加的预定力压印角膜来测量眼内压并且当施加预定力时检测压印元件移动到角膜中的距离,该距离与眼内压成反比。 还提供了使用眼压计系统来测量眼睛的流体动力特性的方法,特别是流出设备。 眼压计系统包括用于放置成与角膜接触的接触装置和用于致动接触装置的致动设备,使得其一部分向内突出抵靠角膜以提供预定量的扁平化。 该系统还包括检测装置,用于检测何时已经达到预定量的扁平化,以及响应于检测装置的计算单元,用于基于接触装置必须抵靠角膜施加的力量来确定眼内压,以便实现 预定量的压平。 还提供了一种压痕距离检测装置,用于在通过压痕检测眼压时使用。 在实施该方法时,该系统用于检测迫使眼内液从眼中流出的连续步骤之间的眼内压。
