The Ocular Response Analyzer (ORA) is the only instrument capable of measuring Corneal Hysteresis (CH); an indication of the biomechanical properties of the cornea. This information is different from thickness or topography, which are geometrical attributes of the cornea. Corneal Hysteresis represents a tissue property, which provides more comprehensive information about ocular biomechanics. There are over 400 publications about Ocular Response Analyzer in the peer-reviewed literature.
The Corneal Hysteresis measurement has been shown to be consistently associated with, or predictive of, rate of glaucoma visual field progression. In addition, corneal biomechanics are the primary influence on tonometer accuracy. Ocular Response Analyzer's ability to measure Corneal Hysteresis enables the device to provide corneal compensated IOP, called IOPcc, which has been proven to be less influenced by corneal properties than Goldmann or other methods of tonometry.
