While it resembles a classical contact tonometer à la Goldmann, the PASCAL Dynamic Contour Tonometer works on a fundamentally different principle and is packed with advanced features that are only possible due to the advanced, entirely digital, concepts implemented in the PASCAL. Analog-to-digital conversion, digital signal processing and analysis, numerical and graphic (optional) display of data, automatic monitoring of signal and result quality, storage and retrieval of results, customized measurement and display options are just some of the advantages a microprocessor-based instrument concept offers.

Direct measurement of pressure eliminates systematic errors from force-to-pressure conversion.
Numerical display of result on LCD screen avoids operator bias and reading errors.
Audio feedback during measurement aids alignment and data taking.
Completely objective measurement – no mires to align!
Quality reading ("Q score”) avoids erroneous readings due to poor data quality.
Automatic end-point detection terminates measurement when pre-set quality score is reached.
Attaches to slitlamp like the familiar Goldmann tonometer.
No need for fluorescein. Room lights can remain on.
Reads IOP dynamically at 100 times/second.
All functions are accessed with the unique Blue Knob – easy, single button operation.
Self-calibrates at the beginning of every measurement – no calibration required.

: THE PASCAL is mounted on any slitlamp like the traditional applanation tonometer.
