Pascal dynamic contour tonometer (dct)
I have two Pascal Tonometers that were purchased new in 2009. I also have one mini laptop pc with the Pascal DataWizard Software. These units work flawlessly. I am selling them because I have been using my traditional Goldmann tonometers more lately. The technology is sound and very accurate. This is a must for any glaucoma Optometry or Ophthalmology practice. I would like to sell both units together but would consider selling only one at a time. Below is the website for the DCT and the information from that site.

The PASCAL 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 tonometer provides an accurate and direct measurement of true IOP, which is independent of inter-individual variations in corneal properties and biomechanics.
Note that IOP measurement is accurate even on post-LASIK and keratoconic eyes.
PASCAL detects and accurately measures the dynamic fluctuations in IOP and thus allows for a more detailed assessment of the pressure range to which the eye is subjected due to pulsatile ocular blood flow.
PASCAL repeatedly samples intraocular pressure at a rate of 100 times per second. The ocular pulse amplitude (OPA) and the systemic pulse rate are continuously measured and recorded by the instrument. In addition, the ocular pressure pulse is graphically represented on the patient report.
A disposable silicone tip cover prevents cross contamination and greatly reduces the likelihood of corneal abrasion, even with inexperienced users.
Convenient documentation and visualization of numerical results and IOP curves is possible with the optional wireless printer and PASCAL DataWizard PC software.
