A device for calibration of a dynamic tonometer was developed. The principle of operation of the device is based on measurement of the rigidity of a dynamic system comprising a vibrator and the elastic surface of the eye. The rigidity is determined by monitoring the oscillation period of the system. The rigidity of the cornea is mathematically correlated with eye pressure. A flat spring with given...
The principle of action of a dynamic tonometer for measuring intraocular pressure is considered. It is based on monitoring of the oscillation period of the dynamic system of tonometer elements and the eye. A model of the tonometer-eye oscillation system is presented. The effect of eye elements (eyelid and cornea) on the oscillation period of the system is considered. An example of practical implementation...
