Description
Condition & Warranty
Used. This Reichert G3 Ocular Response Analyzer (ORA) has been fully tested and is in excellent working order. The non-contact air-puff fluidics fire cleanly, the infrared optical sensors track corneal deformation accurately, and the touchscreen interface is bright and responsive. All internal diagnostic parameters—including Corneal Hysteresis (CH) and Corneal-Compensated Intraocular Pressure (IOPcc)—calculate seamlessly. The chassis shows minor signs of cosmetic wear as expected for used automated clinical equipment. Carefully tested before shipping. Covered by a 90-day warranty on parts and workmanship.
Reichert G3 Ocular Response Analyzer (ORA) — Used Non-Contact Tonometer w/ Corneal Hysteresis
The Reichert G3 Ocular Response Analyzer (ORA) is a revolutionary non-contact diagnostic platform that goes far beyond traditional tonometry by evaluating the dynamic biomechanical properties of the cornea. Utilizing a patented, ultra-fast air-puff sequence, the G3 measures the cornea’s bi-directional applanation response. This process isolates Corneal Hysteresis (CH)—a critical metric reflecting the tissue’s ability to absorb and dissipate energy—providing vital insight into corneal biomechanical resistance.
Unlike standard applanation or non-contact tonometers whose readings can be significantly skewed by thick, thin, or post-refractive corneas (such as post-LASIK/PRK), the G3 generates Corneal-Compensated Intraocular Pressure (IOPcc). This measurement provides an accurate intraocular pressure reading independent of corneal thickness or biomechanics. Combined with traditional Goldmann-Correlated Pressure (IOPg) and an intuitive motorized alignment interface, this used G3 workstation is an essential asset for advanced glaucoma risk assessment and refractive surgery screening.
Research published in the National Library of Medicine confirms that Corneal Hysteresis measured by the Reichert ORA is an independent risk factor for glaucoma progression, where lower CH values strongly correlate with faster rates of visual field loss and optic nerve damage regardless of baseline intraocular pressure.
Why Practices Choose the Reichert G3 ORA
-
Exclusive Corneal Hysteresis (CH) Tracking — Measures fundamental tissue biomechanics to identify patients at high risk for glaucoma progression before structural nerve loss occurs
-
Corneal-Compensated IOP (IOPcc) — Delivers highly accurate pressure metrics that are less influenced by corneal thickness, curvature, or biomechanical alterations from prior LASIK/PRK
-
Non-Contact Air-Puff Precision — Gentle, ultra-rapid air impulse eliminates physical corneal contact, topical anesthetics, and cross-contamination risks
-
Automated 3D Motorized Alignment — Advanced tracking system automatically centers on the pupil and triggers the measurement sequence for fast, technician-friendly operations
-
Objective Biomechanical Signal Analysis — Evaluates real-time corneal deformation waveforms, providing an objective quality score (Waveform Score) for every measurement
-
Comprehensive Glaucoma & Refractive Screening — Serves as a vital dual-purpose tool for identifying glaucoma susceptibility and screening candidates for ectasia prior to corneal refractive surgery
-
Compact Integrated Workstation — Features an all-in-one footprint with an integrated touchscreen monitor and internal data processing suite
Clinical Applications
-
Advanced Glaucoma Risk Assessment leveraging Corneal Hysteresis (CH) to stratify high-risk patients and customize target IOP goals
-
Post-Refractive Surgery Tonometry obtaining accurate IOPcc readings in post-LASIK, PRK, or SMILE patients where standard applanation yields artificially low pressure values
-
Refractive Surgery Pre-Op Screenings evaluating preoperative corneal biomechanical integrity to detect early subclinical keratoconus or ectasia risks
-
Normotensive Glaucoma (NTG) Evaluations detecting compromised corneal biomechanics in patients with progressive visual field loss despite “normal” standard pressure readings
Who This Is For
-
Glaucoma Specialists and Ophthalmologists seeking a proven, independent risk factor tool to track aggressive visual field loss and set precise target pressures
-
Refractive and Corneal Surgeons requiring objective biomechanical evaluations before performing LASIK, PRK, or corneal cross-linking
-
Progressive Comprehensive Practices looking to upgrade standard non-contact air-puff tonometers with high-tier biomechanical diagnostics
