An estimated 39,000 diagnostic OCT scans are taken in America daily– a number that is only growing as the technology becomes more mainstream and affordable. At the forefront of this ophthalmic tomography, is no other than major manufacturer Carl Zeiss Meditec and their Spectral Domain Optical Coherence Topographers. Since its inception, the Cirrus is undoubtedly the market leader, and in our opinions, makes the best OCT offered anywhere. It starts with the fact that no external computer, monitor, or anything for that matter is necessary to operate it; everything is built-in and fit into a giant boat-like triangular thing. Except it’s not a boat thing, it’s a yacht carrying the greatest and latest Ophthalmic technology bundled into a large computer that still sits on your pretest table. Yes, it is big, but it’s extraordinary to look at; overly impressive, awe-inspiringly futuristic and robotic. But you don’t buy an OCT to look at it (it will make your Optometric practice seem more scientific and medically versed however) you make this investment for the imagery, and Cirrus delivers on all fronts. Cirrus gives you the ability to view pathologies from multiple vantage points—and with a range of at-a-glance visualization formats. From the basic LSO Fundus Imaging, to the Macular Thickness Map, to the HD 5 Line Raster display, to the 3D visualization…you’ll be able to assess your patient’s condition and determine the appropriate course of action better than ever before. And that’s before we’ve even discussed the data-packed Cirrus Cube. It is the literal trophy of owning a Cirrus and a tightly packed, detail-rich cube of data (captured in just seconds) that allows you to visualize and analyze your patient’s condition. The multi-layered cube is a product of 67 million total data points being produced multi-dimensionally in a 2.4 second scan– what a way to explore pathology. It’s possible by directing tightly spaced A and B-scans in 512×128 scan patterns which closely capture subtle defects or central fovea pathology. This data is then fed into Zeiss algorithms and compared with normative data for accurate segmentation and reproducible measurements. This makes capturing the 3-D cube only the beginning, granting you the ability to see beyond the scan and transform information into insight. 


OUR TAKE: Cirrus offers the best of the best for Optical Coherence Tomography and a game changer for pathology detection in your practice.

Generating a comprehensive cube of data is only the beginning. Cirrus gives you the ability to see beyond the scan and transform information into insight, becoming an indispensable part of your day-to-day clinical decision-making process.


  • Algorithm Excellence – Carl Zeiss Meditec and its research collaborators have developed advanced algorithms to measure and display layers.
  • Automatic, Accurate Centering of the Measurement – FoveaFinder™ and AutoCenter™ technologies ensure that measurements are made in the correct locations, taking the pressure off the operator to center the scans perfectly.
  • Cube Registration to Track Change – Cirrus data cubes are automatically registered with data from prior visits, allowing for point-to-point comparisons.
  • Normative Data – Diversified normative databases for ONH, RNFL and macular thickness facilitate at-a-glance assessments.


Cirrus offers unsurpassed OCT technology. Capturing a tightly packed, detail-rich cube of data in just seconds, it allows you to both visualize and analyze your patient’s condition. Because the cube is populated with such high-density data, you can explore pathologies without requiring additional scan patterns.

  • Scan With Greater Granularity – Closely spaced B-scans within the cube ensure that even small areas of pathology are captured and easily viewable, unlike scans that are spaced further apart, which may miss the central fovea or nearby subtle defects.
  • Enhance Your Analysis – Millions of data points from the cube are fed into ZEISS proprietary algorithms for accurate segmentation, reproducible measurements and registration for change analysis.

With Cirrus, all traditional RNFL measurements based on the 3.4 mm circle are present; however, Cirrus enables you to see past the circle-based assessments. Spotting wedge defects and other patterns of loss is simplified with Deviation Maps, which show comparisons to normative data for each superpixel in the 6 x 6 mm area.

Unique Cirrus Optic Nerve Head analysis provides automated identification of the optic disc and cup boundaries. The analysis is generated using the dense data in the Optic Disc 200 x 200 data cube in tandem with a proprietary ZEISS algorithm. This algorithm precisely measures the neuroretinal rim while accounting for tilted discs, disruptions to the RPE and other challenging pathologies.

  • AutoCenter™ – After the scan is acquired, Cirrus automatically centers the measurement circle around the disc. The placement is not operator-dependent.

  • Guided Progression Analysis™ – (GPA) compares RNFL thickness measurements from data cubes obtained during different visits and allows you to determine if statistically significant change has occurred over time.

  • The HFA-Cirrus Combined Report – available exclusively with ZEISS FORUM®, summarizes patient structure and function information in a single display.

Cirrus gives you the ability to view pathologies from multiple vantage points—and with a range of at-a-glance visualization formats, you’ll be able to better assess your patient’s condition and determine the appropriate course of action.

Cirrus offers anterior segment imaging of the angle and cornea and the ability to measure central cornea thickness.

With high-density cube data and proven segmentation, Cirrus delivers a diagnostic analysis you can trust.


With legendary ZEISS optics and Cirrus, you’ll experience brilliant, detail-rich visuals to help you diagnose and care for your patient.

Cirrus uses Selective Pixel Profiling™ to optimize each pixel in its HD Raster Scans. It produces imagery that goes beyond mere image-averaging. It’s a difference you need to see to believe.


Your refurbished Zeiss Cirrus 4000 OCT will come pre-installed on an inherent Windows 7 OS running Cirrus V. 7.0 or greater.

The Cirrus 4000 performs 27,000 a-scans per second, analyzing 1,024 data points per scan within a 512 x 128 pattern.

You bet. The Cirrus 4000, along with all Cirrus Spectral Domain OCTs, will integrate directly with EHR/EMR and Zeiss’ FORUM software.
