Abstract: A non-contact tonometer comprises a fluid pump system configured and mounted to dissipate vibration energy to reduce the effect of vibrations on measurement components caused by the stroke of a piston with respect to a cylinder in the fuid pump system. In a preferred embodiment, a compression chamber receiving a piston and plenum chamber containing a pressure sensing device are spaced apart from one another and connected by a flow tube formed of a vibration damping material, and at least one vibration damping element is provided between the cylinder and a support frame of the non-contact tonometer.

Abstract: A fluid pump system of a non-contact tonometer is numerically simulated through its compression stroke by a simulation software program. System dynamic behavior is modeled for a variety of piston diameters, whereby an optimal piston diameter or range of piston diameters is selected in view of stoke length limitations and target applanation pressure requirements.
