Description
Zeiss Cirrus 400 OCT Refurbished — Spectral-Domain Retinal Imaging

A National Library of Medicine study confirms that spectral-domain OCT macular layer analysis provides superior diagnostic ability across all stages of glaucoma compared to conventional single-layer methods.
What’s Included
- Zeiss Cirrus 400 OCT main unit
- Patient chin rest and forehead support assembly
- Integrated acquisition computer with Cirrus OCT software
- ZEISS DICOM Gateway connectivity
- Power cable and accessories
- 6-month Digital Eye Center warranty
Why Practices Choose the Zeiss Cirrus 400
- Live OCT Fundus™ Technology — generates the fundus reference image directly from OCT scan data, eliminating the need for a separate line-scanning ophthalmoscope and reducing system cost and complexity.
- 27,000 A-Scans Per Second — captures high-density macular and RNFL cubes with minimal motion artifact, even in patients with poor fixation.
- 5 μm Axial Resolution — resolves individual retinal layers with precision, enabling accurate RNFL and macular thickness measurements benchmarked against a built-in normative database.
- Guided Progression Analysis (GPA) — automatically compares current scans to baseline for longitudinal glaucoma monitoring, flagging statistically significant change over time.
- Comprehensive Software Suite — includes Macular Thickness, RNFL Thickness, ONH Analysis, Macular Change Analysis, Anterior Segment Imaging, and 3D Display modules.
- DICOM Connectivity — integrates with practice EMR and PACS systems via the ZEISS DICOM Gateway for seamless data management.
- Cost-Effective Entry Point — delivers the core Cirrus HD-OCT platform capabilities at a fraction of the cost of newer models, making spectral-domain OCT accessible for smaller practices and mobile programs.
Clinical Applications
- Glaucoma Detection and Monitoring — RNFL and optic nerve head analysis with normative database comparison and automated GPA progression tracking.
- Macular Disease Assessment — quantitative macular thickness maps and layer-by-layer analysis for AMD, diabetic macular edema, and epiretinal membrane evaluation.
- Diabetic Retinopathy Screening — structural retinal thickness measurements to identify early changes before visual symptoms develop.
- Anterior Segment Imaging — corneal cross-section and anterior chamber visualization for cataract and glaucoma surgical planning.
- Longitudinal Disease Tracking — Macular Change Analysis and GPA software enable reliable long-term follow-up and early detection of disease progression.
Who This Is For
- Solo and Small Group Ophthalmology Practices — seeking cost-effective entry into spectral-domain OCT without sacrificing clinical capability.
- Optometry Practices — adding OCT for glaucoma co-management, macular screening, and diabetic eye care on a proven, well-supported platform.
- Mobile Eye Care Programs — needing a capable, established OCT system at a lower investment than current-generation devices.
- Teaching and Research Settings — where Cirrus HD-OCT familiarity is established and budget constraints favor the 400 platform over newer models.
