The World’s Most Accurate Tonometer

The PASCAL Dynamic Contour Tonometer (DCT) is a third-generation, digital,
contact tonometer for ophthalmological applications. The slitlamp mounted
device furnishes a numeric output of intra-ocular pressure (IOP) and of ocular
pulse amplitude (OPA) upon touching the cornea for a few seconds. It measures
pulsatile IOP directly and continuously (dynamically).


Features
Direct measurement of pressure eliminates systematic errors from force-topressure
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.

Clinical Benefits
Unlike applanation tonometers, which are influenced by corneal thickness
and other characteristics of the cornea, and hence may produce misleading
estimates of IOP, the PASCAL provides an accurate, direct measurement
of true IOP which is independent of inter-individual variations in corneal
properties and biomechanics.
IOP measurement is accurate even on post-LASIK and keratoconic eyes.
PASCAL detects and accurately measures the dynamic fluctuations in IOP
and thus permits a more detailed assessment of the pressure range to
which the eye is subjected due to pulsatile ocular blood flow.
Silicone tip covers prevent cross-contamination and eliminate possibility of
corneal abrasion, even with an inexperienced user.
Convenient documentation and visualization of IOP curve with optional
wireless printer or PASCAL DataWizard PC software.
