Ocular Response Analyzer G3 (ORA G3)
Brand:Reichert
Biomechanical tonometer measuring corneal hysteresis (CH) and cornea-independent IOP (IOPcc). Additional insight for glaucoma risk and corneal assessment.

Air pulse + deformation analysis
Product Description
The Ocular Response Analyzer G3 analyzes the bidirectional corneal response to an air pulse, measuring corneal hysteresis (CH) and corneal resistance factor (CRF); it provides corneal-compensated IOP (IOPcc) and Goldmann-correlated IOP (IOPg). IOPcc is largely independent of corneal thickness and structure; corneal hysteresis is a parameter associated with glaucoma progression risk that standard tonometers do not provide. It delivers additional clinical value in pre-refractive surgery corneal assessment and glaucoma follow-up.
