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.
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.
