Zeiss Cirrus 4000 OCT – Refurbished

Post date November 2, 2020

Specifications for Zeiss Cirrus 4000

The ZEISS Cirrus HD-OCT 4000 (Cirrus HD-OCT or Cirrus) enables examination of the posterior and anterior of the eye at an extremely fine spatial scale, without surgical biopsy or even any contact with the eye.

The Cirrus HD-OCT builds on and refines the retinal imaging technology first introduced with the ZEISS Stratus OCT™.

Employing the advanced imaging technology of spectral-domain optical coherence tomography, Cirrus HD-OCT acquires OCT data about 70 times faster (27,000 vs. 400 A-scans per second) and with better resolution (5 μm vs. ~10 μm axial resolution in tissue) than first-generation OCT technology.

Cirrus acquires whole cubes of OCT image data, composed of hundreds of line scans, at about the same time as Stratus acquires a six-line scan. You can view these data cubes in three planes or through three dimensions, giving you access to extensive retinal image data in one scan.

Specifications for Cirrus 4000

The Zeiss Cirrus 4000 HD-OCT with Retinal Nerve Fiber Layer (RNFL), Macular, Optic Nerve Head, and Ganglion Cell Normative Databases is indicated for in-vivo viewing, axial cross-sectional, and three-dimensional imaging and measurement of anterior and posterior ocular structures.

Indications for Use

The Cirrus HD-OCT is a non-contact, high-resolution tomographic and biomicroscopic imaging device. It is indicated for in-vivo viewing, axial cross-sectional, and three-dimensional imaging and measurement of anterior and posterior ocular structures, including cornea, retina, retinal nerve fiber layer, ganglion cell plus inner plexiform layer, macula, and optic nerve head.

The Cirrus normative databases are quantitative tools for comparing retinal nerve fiber layer thickness, macular thickness, ganglion cell plus inner plexiform layer thickness, and optic nerve head measurements to a database of normal subjects.

The Cirrus HD-OCT is intended for use as a diagnostic device to aid in detecting and managing ocular diseases including, but not limited to, macular holes, cystoid macular edema, diabetic retinopathy, age-related macular degeneration, and glaucoma.

Note: The Zeiss Cirrus 4000 HD-OCT is not intended to be used as the sole diagnostic for disease.

Essential Performance

The Essential Performance of the Zeiss Cirrus 4000 is to provide accurate measurements of the anterior and posterior ocular structure.

Patient Population

The Cirrus HD-OCT may be used on all adults needing diagnostic eye evaluation. This includes (but is not limited to) patients with the following disabilities or challenges:

• Wheelchair user
• Very low or not measurable visual acuity
• Fixation problems
• Postural problems
• Deafness
• Large body, but not those above 99th percentile based on anthropomorphic data

There is a general requirement that the patient sit upright and place their face in the chin and forehead for the rest of the instrument (with or without supplemental human or mechanical support).

The Zeiss Cirrus 4000 HD-OCT is designed for in-vivo viewing, axial cross-sectional imaging, and three-dimensional measurement of anterior and posterior ocular structures.

Optovue iVue OCT – Refurbished

Post date November 17, 2020

The Optovue iVue is the benchmark for eye care practitioners seeking unmatched OCT performance and value – with capabilities you would expect to cost far more.

At first glance, the iVue® OCT system may strike you as a simplified OCT. Lightweight and modular, it can be positioned wherever it suits your needs.

As for operational ease, from the moment you turn the system on, its familiar slit-lamp-style design makes scanning a breeze. But when you look deeper at the resulting diagnostic screens, you get a different picture—the big one.

Extras are Standard

The iVue provides an impressive array of standard features. OCT scanning and resolution are excellent.

The resulting reports for retina, optic nerve head, and anterior segment assessment are comprehensive, providing capabilities for which other systems charge extra—if they have them at all.

Some are Optovue exclusives such as FLV% and GLV% analysis and the iWellnessExam® for more personalized patient eye care.

Advanced diagnostic imaging capabilities

The iVue® platform supports highly advanced diagnostic imaging applications off the shelf, including the retina, optic nerve head, and anterior segment assessments.

Ganglion Cell Complex (GCC) – Advanced GCC imaging reveals ganglion cell and axon loss in optic nerve head disease. GCC thickness mapping improves clarity in structural change identification. Optovue’s exclusive FLV% and GLV% analyses increase GCC sensitivity and specificity.
3D and En Face—The 3D and en face view provides a multi-layer, high-resolution virtual dissection of the retina and optic disc and depicts them in a way that preserves the retina’s natural curvature. This reduces distortion for simpler interpretation and enhanced 3D visual assessment.
Cornea Advance—Cornea Advance expands iVue’s clinical utility for pre-surgical planning and post-operative assessment. It enhances anterior chamber and cornea analysis via anterior segment angle measurements and pachymetry with change analysis.

Essential imaging capabilities

Retina mapping and analysis – Retina mapping with normative comparison, retina change analysis, and 3D retinal imaging with en-face presentation are all depicted in high-resolution, easy-to-interpret color reports.
Optic disc and RNFL assessment – Advanced capabilities include RNFL and GCC® combination reports with normative comparison and RNFL and GCC trend analysis —both standard.
Comprehensive anterior segment analysis – Anterior segment capabilities include highly detailed reports for pachymetry mapping with change analysis and anterior segment angle measurement.

iWellnessExam

The iWellnessExam® is an Optovue exclusive available on all iSeries OCT systems that delivers a quick, easy OCT scan to promote better overall patient eye health.

Its usefulness stems from a single, comprehensive report that depicts:

Retinal thickness and GCC® thickness with normative comparison
Symmetry analysis
FLV% and GLV%, proprietary Optovue GCC metrics that provide important information to aid in ocular disease diagnosis and management
Eight high-resolution B-scans

iWellnessExam benefits patients

Ultimately iWellness benefits patients by helping them become more involved in their eye health. Scanning is simple and quick, and each patient receives comprehensive, personalized eye health information in an easy-to-understand report.

iWellnessExam benefits eye care providers

iWellness benefits ECPs by providing a valuable assessment tool that can reveal the need for more extensive imaging. It also streamlines the exam process by quickly confirming normal—or helping you more efficiently diagnose pathology.

Optovue’s current iWellnessExam users have affirmed that the iWellnessExam improves patient involvement, loyalty, and retention. This helps you grow and differentiate your eye care practice while also providing a new revenue stream.

Networking Solutions

NetVue Pro allows viewing and modifying images from a single Optovue OCT system on up to eight review stations. In addition, with NetVue Pro, new patient scans may be captured while existing scans are reviewed.
NetVue Enterprise enables viewing and modifying images from multiple Optovue OCT systems on up to 20 review stations.
NetVue Web is a browser-based solution that brings Optovue OCT images to a smartphone, tablet, or PC.

Zeiss Cirrus 5000 OCT – Refurbished

Post date August 26, 2020

The Zeiss Cirrus 5000 HD-OCT improves on the Cirrus 4000 model in hardware and software. It retains the most essential features of the 4000 model and upgrades on hardware and Smart HD Scans.

Eye motion artifacts are reduced with FastTrac retinal tracking, which enables tracking of the current scan to the position of a previous scan, which provides a better progression analysis.

The monitor has been improved, too, with a 19-inch display for high-definition scans.
