Where this comes from

Abstract

A miniaturized hand-held applanation tonometer is introduced, in which a special cone prism is employed to be an applanation probe to flatten the eye vertically. The self-weight of the probe is just the applanation force, and the applanation area of the ocular cornea is monitored by the optoelectronic signal. The preliminary test demonstrates its good clinical acceptance and its accuracy meeting clinical needs.
