The Reichert 7CR from Reichert Technoligies is designed to use a patented bi-directional applanation process to characterize the bio-mechanical properties of the cornea and reduce their impact on the IOP measurement. Thus making the eye checking procedure more accurate and speedy. The said measurement also known as the Corneal Compensated IOP (IOPcc) is minimally affected by corneal visco-elastic properties, thickness, or surgical procedures such as LASIK or PRK. As such, IOPcc is a better indicator of glaucoma than other methods of tonometry, including Goldmann Applanation.
