The optical engine captures high-resolution cross-sectional scans, the mechanical chinrest moves smoothly, and the internal computer system has been upgraded and optimized with Windows 10 for enhanced clinical security and speed. The unit shows minor signs of usage as expected for used diagnostic equipment. Carefully tested before shipping. Covered by a 90-day warranty on parts and workmanship.
Carl Zeiss Cirrus 500 HD-OCT — Used with Windows 10 Upgrade
The Carl Zeiss Cirrus 500 is an industry-standard, high-definition spectral-domain optical coherence tomography (SD-OCT) system designed to deliver exceptional diagnostic imaging of the posterior segment. This specific unit features an upgraded Windows 10 operating platform, providing modern network security, faster processing speeds, and smoother integration into electronic medical records (EMR) systems. Utilizing advanced line-scanning technology, the Cirrus 500 offers highly detailed cross-sectional tissue visualizations, allowing clinicians to inspect individual retinal layers with micrometer-scale resolution.
Equipped with proprietary Zeiss algorithms, the Cirrus 500 excels at early detection and management of glaucoma and retinal disease. It features the standard Macular Cube 512×128 scan and specialized Optic Nerve Head (ONH) tracking, which automatically cross-references data against a comprehensive normative database. With its proven track record for repeatability, this refurbished Windows 10 model provides top-tier ophthalmic imaging without the overhead of a brand-new system.
Research published in the National Library of Medicine confirms that spectral-domain OCT systems provide highly reproducible retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) measurements, serving as the definitive clinical benchmark for tracking progressive structural damage in glaucoma and macular pathologies.
Why Practices Choose the Carl Zeiss Cirrus 500
-
Windows 10 Operating System — Upgraded architecture provides modern cybersecurity compliance, faster data handling, and reliable practice networking
-
High-Definition Retinal Mapping — Captures dense data cubes instantly, allowing for precise cross-sectional slicing of macular and optic nerve structures
-
Fovea Finder™ and Fast-Acuity Alignment — Automatically centers the scan on the patient’s fovea or optic disc, ensuring repeatable tracking across multiple visits
-
Ganglion Cell Analysis (GCA) — Maps the macular ganglion cell-inner plexiform layer to identify early structural loss from glaucoma before visual field defects appear
-
Guided Progression Analysis (GPA) — Compares historical exam data to quantify true structural change over time, distinguishing disease progression from clinical noise
-
Compact Single-Table Footprint — Integrates the optical head and data processing computer into an efficient tabletop unit that easily fits standard exam rooms
-
Extensive Normative Database — Instantly compares age- and race-matched patient tissue thickness against healthy baselines for immediate diagnostic confidence
Clinical Applications
-
Glaucoma Diagnosis and Management through high-precision RNFL, ONH, and Ganglion Cell layer thickness assessments
-
Macular Disease Assessment for the tracking of age-related macular degeneration (AMD), diabetic macular edema (DME), and macular holes
-
Anterior Segment Imaging (with appropriate lens modules) for evaluating corneal thickness and anterior chamber angles
-
Pre- and Post-Operative Retinal Tracking to closely monitor anatomical restoration following vitreoretinal surgeries
