Reichert Ocular Response Analyzer® G3
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..
Ocular Response Analyzer is made in the USA.

- A New Glaucoma "Vital Sign": How Corneal Hysteresis is Improving Glaucoma Patient Management.
By John Berdahl, MD, Felipe Medeiros, MD, PhD, Nathan Radcliffe, MD, and Davinder S. Grover, MD, MPH
"Science has clearly demonstrated that CH (Corneal Hysteresis) is tied to glaucoma progression risk." - Felipe Medeiros, MD
Corneal Hysteresis: An Essential Factor for Glaucoma Diagnosis and Management.
By Felipe Medeiros, MD, PhD, Nathan Radcliffe, MD, and James Thimons, OD, FAAO
"Even after adjusting for age, intraocular pressure central corneal thickness, pattern standard deviation (PSD) and treatment, CH was still highly predictive of glaucoma development. Every 1mmHg lower CH was associated with a 21% increase in the risk of developing glaucoma."
- Taking Glaucoma Risk Assessment to the Next Level: The Role of Corneal Hysteresis
- A group of glaucoma specialists (including Robert M. Weinreb, MD; Jamie D. Brandt, MD; Nathan M. Radcliffe, MD; Felipe A. Medeiros, MD) discuss data supporting the role of Corneal Hysteresis (CH) in glaucoma risk assessment. The experts give a historical perspective on CH, explain how it works as a potential biomarker, and indicate which patients are good candidates and provide guidance on incorporating CH into clinical practice. Importantly, they demonstrate how recent clinical research findings show compelling evidence that CH is a powerful asset for assessing patients at high risk for developing glaucoma and disease progression.
