Reichert 7CR Auto Tonometer + Corneal Response Technology
IOP is the only modifiable risk factor for glaucoma and, as such, accurate tonometry is of critical importance in the diagnosis and management of this disease. It is widely
recognized that the current gold standard for measuring pressure, the Goldmann Applanation Tonometer (GAT), has considerable flaws.
Goldmann, and other current tonometers, are significantly influenced by corneal properties such as rigidity and thickness. Though it has been shown that GAT provides clinically
reliable measurements in eyes with “average” corneas, we now know that many corneas vary more significantly from average than previously thought.
Numerous Studies have shown that thicker corneas overstate IOP values and thinner corneas understate IOP. However, thickness does not adequately describe corneal biomechanical
properties, making the use of CCT-based correction algorithms questionable at best. In fact, researchers have concluded that correcting IOP based on CCT can lead not only to
errors in the magnitude, but also in the direction of the adjustment. “ Correction nomograms that adjust GAT IOP based solely on CCT are neither valid nor useful in individual
patients.” – Pg 18. Robert N. Weinreb, James D. Brandt, David Garway- Heath and Felipe Medeiros. World Glaucoma Association on Intraocular Pressure; Consensus Series 4; May 5,

Reichert’s 7CR Auto Tonometer + Corneal Response Technology takes corneal biomechanical properties into consideration, providing Corneal Compensated IOP (IOPcc) – a pressure
measurement that is significantly less affected by the cornea than other methods of tonometry. The instrument’s unique ability to simultaneously provide a Goldmanncorrelated IOP
measurement (IOPg) and IOPcc, provides clinicians with a better understanding of patient tonometry values,
enhancing clinicians ability to make critical diagnosis and treatment decisions.
