Pascal Tonometer
Dynamic Contour Tonometer (DCT)
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).
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.
