The Zeiss Cirrus 4000 OCT (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™.
The Zeiss Cirrus 4000 OCT (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. Also known as Cirrus4000.
FEATURES:
- Unprecedented Visualization of Anatomical Details
- HD Layer Maps
- HD Enhanced Raster Scan
- Cirrus HD-OCT Scan Engine
- Correlation Between OCT Scan and Fundus Image
- Superior Image Data
- Designed for efficiency
