Ocular Response Analyzer® (ORA) is the only tonometer that measures Corneal Hysteresis (CH), a superior predictor of glaucoma progression. Corneal Hysteresis is an indication of the biomechanical properties of the cornea differing from thickness or topography, which are geometrical attributes.
“CH measurements are significantly associated with risk of glaucoma progression. Eyes with lower CH had faster rates of visual field loss than those with higher CH.”1
In addition to Corneal Hysteresis, Ocular Response Analyzer provides Corneal Compensated Intraocular Pressure (IOPcc), a better indication of the true pressure, proven to be less influenced by corneal properties than Goldmann or other methods of tonometry
