Ocular Response Analyzer® (ORA) is the only device 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.2
Ocular Response Analyzer® G3 and Corneal Hysteresis:
Make a more confident glaucoma risk assessment, with Corneal Hysteresis. Only Ocular Response Analyzer® G3 from Reichert® measures Corneal Hysteresis (CH), a superior predictor of glaucoma progression, which is more associated with visual field progression than CCT or IOP.1,3,5 Ocular Response Analyzer helps add clarity to your glaucoma decision making process. CPT Code 92145, was published for the Corneal Hysteresis measurement provided by Ocular Response Analyzer..
Insights on the role of Corneal Hysteresis in Glaucoma management.

“Hysteresis is a very powerful risk factor for progression of the disease, and I think it’s one that’s largely overlooked. In fact, if you take Hysteresis out of the central corneal thickness measurement, central corneal thickness might not even be a risk factor for glaucoma progression.
