Dynamic Contour Tonometer
The PASCAL TONOMETER - Dynamic Contour Tonometer
(DCT) is a 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).
PASCAL Tonometer offers valuable 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 Tonometer 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.
A disposable silicone tip cover prevents cross
contamination and greatly reduces the likelihood of corneal abrasion,
even with an inexperienced user.
Convenient documentation and visualization of numerical
results and of IOP curves is possible with the optional wireless
printer or PASCAL DataWizard PC software.
