Corneal Hysteresis and IOPcc
Ocular Response Analyzer® (ORA) G3 is the only device that measures Corneal Hysteresis (CH) and Corneal Compensated IOP (IOPcc). Corneal Hysteresis has consistently shown to be a more powerful predictor of, and strongly associated with, glaucoma progression, more so than key risk factors such as IOP and CCT. IOPcc is a pressure measurement that is less affected by corneal properties and more associated with glaucoma risk than Goldmann and other tonometers. Ocular Response Analyzer is engineered, designed, and assembled in USA.
How is Corneal Hysteresis measured?
Corneal Hysteresis is the difference in the inward and outward pressure values obtained during the patented dynamic bi-directional applanation process utilized by the Ocular Response Analyzer. It is a characterization of the cornea’s ability to absorb and dissipate energy, which is a function of visco-elastic biomechanical properties of the cornea.
Unparalleled user experience.
Measurements could not be quicker or simpler with Ocular Response Analyzer G3. A single touch of the intuitive user interface initiates a fully automated alignment and measurement, simultaneously displaying Corneal Compensated IOP (IOPcc), Corneal Hysteresis (CH), Goldmann correlated IOP (IOPg), and Waveform Score (WS).
Confidence, reliability and efficiency.
The advanced, patent-pending Waveform Score feature, combined with Reichert’s unique intelligent averaging technique, enhances measurement reliability and repeatability so operators can be confident in the accuracy of the measurement results. Operators can easily access all functions through the integrated touch screen display, including export of patient data for effortless EMR integration. Delegate your tonometry and Corneal Hysteresis measurements to trained technicians with ease.
Non-contact saves time and money.
Because the Ocular Response Analyzer G3 measurement is rapid and non-contact the use of topical anesthesia and/or fluorescein drops is not required, saving time and money. In addition, the risk of cross contamination is greatly reduced. The need for time-consuming sterilization of tonometer prisms, costly replacement of prisms, or use of expensive disposables is eliminated.
