PASCAL Dynamic Contour Tonometer System

The PASCAL Dynamic Contour Tonometer (DCT) is a digital contact tonometer for ophthalmological applications. Upon touching the cornea for a few seconds, this slit lamp mounted device furnishes a numeric output of intra-ocular pressure (IOP) and of ocular pulse amplitude (OPA). It measures pulsatile IOP directly and continuously (dynamically). Unlike applanation tonometers, which are influenced by corneal thickness and other characteristics of the cornea, the PASCAL tonometer provides accurate and direct measurement of true IOP – eliminating the potential for misleading estimates of IOP.
