Extended insights

Precise corneal topography and visualization

Equipped with a variety of measurement capabilities, the ZEISS ATLAS 500 quickly captures relevant corneal properties with high resolution images and videos.

The Placido-based measurements provide a variety of corneal topography analysis options:

  • Summary/custom view including all common topographic maps
  • Elevation (spheric, aspheric and aspheric-toric)
  • Corneal wavefront analysis
  • Optical quality analysis
  • Contact lens fitting

Extended insights

Tear film meniscus

The device features image and video capture under white and blue light conditions. The magnification can be changed allowing the capture of images with a wide visual field such as the tear meniscus and corneal redness

Static and dynamic pupillometry

Analyze pupil size and decentration in scotopic, mesopic and photopic light conditions. Choose between static and dynamic acquisition modes.

Contact lens fitting

The luminous source with cobalt blue light allows you to analyze the clearance of rigid contact lenses in fluorescein and detects corneal staining and scars. Simulate the fit of rigid contact lenses based on the internal databases of the lens manufacturers.

Optimized design

Easy operation and quick data acquisition

With its proven performance, advanced features and streamlined, contemporary design, the ZEISS ATLAS 500 is designed to fit into any modern clinic or practice environment and provides a positive experience for both operator and patients.

Swivel-out measurement head
Swivel-out measurement head significantly reduces nasal shadows. [BEFORE] Measurement in center position: nasal shadows visible. [AFTER] Measurement head in angled position: nasal shadows reduced.

Swivel-out measurement head

The unique, swivel-out measurement head helps reduce nasal shadows during data acquisition to increase the captured area of the cornea.

Enhanced working distance

ZEISS ATLAS 500 features two image capture options, which provide both close-up and overview images to evaluate the details of the ocular surface and photograph external structures.

Acquisition support

Alignment instructions on the left guide the operator for correct acquisition.

Digital documentation

Speed up practice workflow with less manual errors

The ZEISS ATLAS 500 is optimized for integration into the ZEISS medical ecosystem. The ZEISS FORUM connectivity enables patient data export, including PDF reports, to optimize your workflow.
