The Reichert 7CR from Reichert Technoligies utilizes a patented bi-directional applanation process to characterize the biomechanical properties of the cornea and reduce their impact on the IOP measurement. This measurement, referred to as 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 risk than other methods of tonometry, including Goldmann Applanation.
The Reichert 7CR is more clinically valid in all subjects, including: normal tension glaucoma patients, primary open angle glaucoma patients, post-LASIK and refractive surgery patients, patients with Fuchs' or corneal edema, keratoconus patients, and patients with thick, thin, or otherwise biomechanically atypical corneas.
Waveform Score ensures reliability of results:
The Reichert 7CR employs an advanced signal-scoring feature that helps ensure the accuracy and reliability of measurement results. Each measurement is assigned a score based on internally-processed signal analysis algorithm. Scores below a certain threshold are indicated as unreliable. When multiple measurements are taken on the same eye, an intelligent averaging technique provides a weighted average, dependent upon the waveform score. No other tonometer provides operators with objective feedback about the quality of the measurement taken!
Non-Contact measurement methodology:
Alignment and measurement with the Reichert 7CR are FULLY AUTOMATED. A collimated air-jet provides gentle force to the cornea while an electro-optical system monitors the applanation process.
