Force-Triggered Applanation Tonometer

US Patent:
4624235, Nov 25, 1986
Filed:
Apr 13, 1984
Appl. No.:
6/599967
Inventors:
Albert C. Krabacher - Lakewood CO
George J. Eilers - Evergreen CO
International Classification:
A61B 316
US Classification:
128652
Abstract:
A portion of the cornea or similar flexible membrane is flattened by urging against the cornea a footplate with a measurable force and deriving a signal proportional to the magnitude of the applanated area of the cornea when the applanating force is compared to a threshold which corresponds to a force equal to a selected reference force on the planar footplate contacting the cornea. When the selected reference force signal is reached the area of the applanated region of the cornea is transferred as a signal for scaling by another signal proportional to the force.
