The PASCAL tonometer from Ziemer Ophthalmic System AG is on the market since almost 10 years. To date it’s the only device that measures IOP fluctuations independently of the patient’s cornea. Independent studies have shown the PASCAL to be the most accurate and precise tonometer available today.

  • True and accurate measurement independent from corneal properties
    like CCT and corneal rigidity
  • Highest repeatability allowing a refined IOP progression analysis
  • True and accurate measurement of both static pressure (IOP)
    and pressure fluctuation (OPA)
  • True and accurate measurement – no late or missed diagnosis
  • Device can be connected to wireless printer or PC and is EMR compatible
  • Automatic self calibration – no additional calibration stepts needed
  • Low risk of cross infection due to sterile sensor caps
