Applanation tonometry based on Imbert-Flick's law and calibrated by Goldmann for clinical application is generally performed today with a standard diameter of the applanation surface of 3.06 mm. This diameter is determined optically by the examiner; the force required for applanation is the measured variable. With electronic, nonoptical definition of the applanation area a reading which cannot be falsified by an error on the part of the examiner can be obtained automatically and considerably faster.
基于伊姆伯特-弗利克定律并经戈德曼校准用于临床的压平眼压测量法，如今通常采用压平表面标准直径为3.06毫米来进行。该直径由检查者通过光学方式确定；压平所需的力是测量变量。通过对压平面积进行电子而非光学定义，可自动且更快地获得一个不会因检查者的误差而被篡改的读数。
