Method for optimizing piston diameter in a non-contact tonometer, and non-contact tonometer having fluid pump designed by said method

摘要

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.
