Reichert Ocular Response Analyzer G3
The Reichert Ocular Response Analyzer G3 goes beyond traditional IOP measurement to deliver Corneal Hysteresis (CH) and Corneal Compensated IOP (IOPcc) — biomechanical metrics that add critical context to glaucoma risk assessment and progression prediction. CH is a more powerful predictor of glaucoma progression than IOP or central corneal thickness alone, and IOPcc provides a pressure reading less influenced by individual corneal properties — reducing the up-to-17 mmHg variance that affects traditional tonometry in normal eyes. Non-contact, no topical anesthesia required, single-touch automated alignment, and a touchscreen interface make the ORA G3 a practical, delegable addition to any pretest workflow focused on glaucoma-aware care. CPT 92145 is established for Corneal Hysteresis measurement.
- Corneal Hysteresis (CH) — stronger predictor of glaucoma progression than IOP + CCT
- Corneal Compensated IOP (IOPcc) — less affected by corneal properties than other tonometers
- Non-contact measurement — no topical anesthesia, no fluorescein required
- Single-touch automated alignment and measurement
- Intuitive touchscreen interface with Waveform Score quality metric
- No chinrest design for patient comfort
- EMR integration via ReichertCapture software (RS-232)
- CPT 92145 established — billable corneal hysteresis measurement
- Designed and assembled in the USA — made in Buffalo, New York
