Technology – Advanced Eye Care

The ZEISS Cirrus HD-OCT 4000 (Cirrus HD-OCT or Cirrus) enable 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™. HD-OCT stands for "high-definition optical coherence tomography." 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), compared to first-generation OCT technology. Cirrus acquires whole cubes of OCT image data, composed of hundreds of line scans, in 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 an extensive amount of retinal image data in one scan. Intended Use The Cirrus 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 Humphrey Visual Field HFA 740 is loaded with features including 19 test patterns, and user designed custom testing capabilities with a testing range out to 90 degrees. Includes an integrated hard drive, eliminating the need for an external computer. The Zeiss 740 also offers SITA, the expert operating system, as an optional feature; however, the Zeiss 740 does include FastPac software as a standard feature, reducing testing time by 40%. Also offers Multiple StatPac Analysis Software test results, which can be printed to compare Visual Field progression over time. Additional features on the Humphrey Visual Field HFA 740 include Full threshold testing, stimulus sizes from Goldman I-V, and stimulus colors in Red or Blue on White are included. The Zeiss 740 Perimeter also includes a VGA monitor hook up for external viewing of test results. The Humphrey Visual Field HFA 740 is a very reliable, yet affordable visual field. The 740 performs most tests flawlessly and at at an acceptable speed. Our units are sold fully refurbished, inspected and upgraded. Our visual fields are also sold with the Zeiss power table with integrated printer. The Humphrey 740 perimeter includes 19 test patterns, user designed custom testing capability with a testing range out to 90 degrees. A 1.1GB hard disk storage is provided, eliminating the need for an external computer. SITA, the expert operating system, is an optional feature on the model Humphrey 740.

Produces incredible images of the unique contours of your eye. This is great for fitting sclerals. Advanced vision-assessment system that combines topography, wavefront, autorefraction, keratometry, and pupillometry — allowing accurate and reliable analysis of corneal aberration.

Used for inspecting the retina and other parts of the eye.
