Focus on Corneal Topographers

THE ATLAS SYSTEM MODEL 9000

Carl Zeiss Meditec
■ Leveraging proven placido disk technology, the next-generation Atlas is a compact, all-in-one system that provides unmatched accuracy and ease-of-use, says CZM. New Zernike corneal wavefront analysis helps optimize aspheric IOL selection and the new PathFinder II Corneal Analysis Software simplifies refractive surgery screening.

Smartcapture Image Analysis analyzes 15 digital images per second during alignment and automatically selects the highest quality image, resulting in decreased dependence on operator technique. The 22-ring placido disk presents a large limbus-to-limbus field of view and its spacing is designed to avoid ring crossover, delivering more reliable results for a wide range of patients.

The ergonomic and compact design combined with an integrated computer makes examination effortless, the company says.

GALILEI DUAL SCHEIMPFLUG ANALYZER

Ziemer USA
■ The Galilei Dual Scheimpflug Analyzer is a high-precision optical system for corneal topography and three-dimensional analysis of the anterior eye segment, based on Revolving Dual Channel Scheimpflug cameras and a placido disk. The Galilei combines the advantages of two technologies: placido imaging furnishes high-accuracy curvature data, while Scheimpflug imaging is optimal for precise elevation data. Within a single scan of less than 2 seconds, the Galilei captures up to 60 high-resolution slit images, placido images and top view images of the anterior segment of the eye. After correction for eye motion, all images are then merged into a single high-precision dataset, to deliver the highest achievable precision in 3-D pachymetry, topography and anterior chamber geometry, says the company.

Galilei also features an adjustable near/far fixation target that allows examination at different accommodation states.
