TONOMETRY CALIBRATION ERRORS

SOURCE: Sandhu SS, Chattopadhyay S, Birch MK, Ray-Chaudhuri N. Frequency of Goldmann applanation tonometer calibration error checks. J Glaucoma 2005;14(3):215-8.

According to this study,
"Calibration error checks should be carried out monthly and tonometers with calibration error greater than +/- 2.5 mmHg returned to the manufacturer for re-calibration."

Does anyone know how to calibrate the Goldmann Tonometer? This is not something I've ever thought about, and yet we have so many glaucoma patients where 1 or 2 mmHg makes a difference in making clinical decisions. This sounds like a question for the manufacturer. If anyone knows anything about this please comment.

    Kevin,
    Essie knows how to calibrate them, however SWEC does not seem to have a strict policy on equipment maintenance in this regard.
    You have to ask Essie to do it.
