The Atlas 9000 is one of the best and most reliable topographers offered by Carl Zeiss. With its patented Cone-of-Focus Alignment System and Arc-Step Algorithm, the Atlas 9000 delivers sub-micron elevation accuracy. Using triangulation, the advanced ATLAS Arc-Step algorithm provides reliable surface reconstruction, 22-ring Placido disk optimized to avoid ring crossover, which means reliable results for a wide range of patients, and long, comfortable 70 mm working distance minimizes focusing error found in “small cone” systems.

Key Features

  • By merging proven ATLAS Placido disk technology with Visante OCT pachymetry, Visante Omni now provides comprehensive anterior and posterior topography.
  • Proven Placido Disk Technology with patented Cone-of-Focus™ Alignment System
  • SmartCapture™ Image Analysis Technology analyzes multiple images during alignment and automatically selects the highest quality image
  • MasterFit™ II Contact Lens Software helps streamline the fitting of gas permeable (GP) lenses and guides you through difficult and specialty fits
  • Data compatibility with previous generation ATLAS Corneal Topography Systems to facilitate data management and patient follow up
  • SmartCapture analyzes 15 digital images per second during alignment and automatically selects the highest quality image
  • Next generation image processing provides more repeatable, reliable results, even in difficult cases
  • Less dependence on operator technique means greater efficiency and fewer repeat exams
  • Corneal Wavefront Analysis takes corneal topography to a new dimension.
  • Using ray tracing technology, the ATLAS displays higher-order corneal aberrations, providing valuable insight for patient education and treatment planning.
  • Educate patients about higher-order aberrations and simulate visual acuity
  • Assess corneal refraction with image simulation and point spread function
  • Measure corneal spherical aberration with Zernike analysis to optimize the selection of aspheric IOLs
  • View the effects of individual higher order corneal aberrations
  • View changes in contrast sensitivity through the modulation transfer function (MTF)
  • Pupil size, measured at two levels of illumination (scotopic and photopic @700 nm), provides insight into optical zone under varying light conditions
  • View centration of LASIK or orthokeratology treatment in relation to pupil center to assess treatment effectiveness
  • Improve multi-focal contact lenses selection by understanding patient’s pupil size at two levels of illumination
  • Streamline contact lens selection and fitting with automatic Horizontal Visible Iris Diameter (HVID) meCompact, integrated system with powerful computer and analysis software
  • Unique chin rest positions patient for easy image capture and wide peripheral coverage and automatically detects OD/OS
  • Non-visible Placido ring illumination is comfortable for even the most light-sensitive patients
