The PASCAL Dynamic Contour Tonometer is a revolutionary new digital tonometer that provides a direct trans-corneal measurement of intra-ocular pressure (IOP), and is sensitive enough to detect the ocular pulse amplitude (OPA) due to the patient's heartbeat.
Using the principle of contour matching instead of applanation, the PASCAL eliminates the systematic errors inherent in all previous tonometers, such as the influence of corneal thickness and rigidity.
Accurate and convenient to use, the PASCAL meets the eye care professional?s need for conclusive, reliable and objective IOP measurements. It is quickly being adopted as a new standard for precision tonometry.

Numerical display of result - Avoids operator bias and reading errors.
-
Audio feedback helps operator to record high quality data
-
Each measurement comes with a Quality score - Avoid erroneous readings due to poor quality
-
Self-calibrating - No calibration requirred
-
Battery operated - No cabling
-
Transparent tip provided for visual control of corneal interfase
-
All functions are accessed with the unique Blue Knob - Easy, single button operation
CLINICAL BENEFITS
-
Unlike applanation tonometers, which are influenced by corneal thivkness and other characteristics of the cornea and hence may produce misleading estimades of IOP, a contour tonometer provides an accurate direct measurement of true IOP which is independent of inter-individual variations in corneal properties and biomechanics.
-
IOP measurementworks correctly even on post-LASIK eyes.
-
PASCAL detects and accurately measures the dynamic pulsatile fluctuations in IOP and thus permits a more datailed assessment of the pressure range to which the eyes is subjected due to pulsatile ocular blood flow.
-
Convenient documentation and visualization of IOP curve with optional wireless printer or PASCAL DataWizard softare for PC.
