Reichert® Ocular Response Analyzer® G3. Make a more confident glaucoma risk assessment, with Corneal Hysteresis. 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 were 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...

Ocular Response Analyzer® G3

An indispensable tool in the glaucoma decision making process. Corneal Hysteresis has consistently shown to be predictive of, or strongly associated with, glaucoma progression, and more powerfully so, than key indicators such as IOP and CCT, making it an indispensable tool in the glaucoma decision making process. Glaucoma is the second leading cause of irreversible blindness in the world. Despite the fact that there are a variety of wellknown risk factors, it can be difficult to diagnose. Beyond diagnosing, predicting an individual patient’s rate of future glaucoma progression is often...

Corneal Compensated IOP (IOPcc): Less affected by corneal properties. Ocular Response Analyzer takes corneal biomechanical properties into consideration, providing Corneal Compensated IOP (IOPcc). The patented bi-directional applanation system enables the measurement of Corneal Hysteresis and IOPcc. Intraocular pressure (IOP) is the only modifiable risk factor for glaucoma. As such, accurate measurement of IOP is critical for proper diagnosis and management. However, it is widely recognized that Goldmann and other tonometers are influenced by corneal properties. While corneal thickness has...

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 ability to absorb and dissipate energy which is a function of visco-elastic biomechanical Unparalleled user experience. Measurements could not be quicker or simpler with Ocular Response Analyzer G3. A single touch of the intuitive user nterface initiates a fully automated simultaneously displaying Corneal Compensated I0P (lOPcc), Corneal Hysteresis (CH), Goldmann correlated I0P (lOPg), and...

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 timeconsuming sterilization of tonometer prisms, costly replacement of prisms, or use of expensive disposables is eliminated. Unique design with patients in mind. Ocular Response Analyzer G3 is designed with no chinrest, which saves time by simplifying patient positioning. This unique design also makes patients...

CPT® Code 92145 published for Corneal Hysteresis. A new CPT code, 92145, has been published specifically for the Corneal Hysteresis measurement provided by the Reichert® Ocular Response Analyzer®. In the 2015 CPT handbook, a new, permanent, Category I CPT code, 92145 (Corneal hysteresis determination, by air impulse stimulation, unilateral or bilateral, with interpretation and report), replaces the prior temporary, Category III CPT code, 0181T. The new code took effect January 1, 2015. For more information regarding CPT Code 92145, please consult your medical billing specialist. Made in the...

Decades of Glaucoma Care Innovation. In 1959 Dr. Bernard “Bernie” Grolman flipped on the radio during his morning commute to American Optical, now Reichert Technologies, and heard a public service announcement about the prevalence of glaucoma. Being familiar with tonometry due to his industry experience he thought, “What if I could create an instrument that eye doctors could use to help diagnose a leading cause of blindness, without touching the cornea?” “The need for a non-contact tonometer was so obvious,” said Grolman, who would spend the next 10 years of his life designing and testing...
