Title:
TONOMETER CALIBRATION TOOL
Document Type and Number:
WIPO Patent Application WO2003088807
Kind Code:
A3
Abstract:
An apparatus (14) for calibrating a non-contact tonometer (12) includes an electronic eye (24) having a damped pressure sensor (60) for receiving a tonometer air pulse and providing a pressure signal in response to the air pulse, and applanation simulation means (70) connected to the pressure sensor for providing a pseudo-applanation event when the pressure signal reaches a predetermined level corresponding to a known IOP measurement standard. A method for calibrating a non-contact tonometer using the inventive calibration apparatus is also described.
