3 ATLAS Model 9000 Overview Next-generation corneal topography system Small footprint, self-contained, no external PC required Modern Windows XP platform Highly accurate Proven Placido disk technology, found in more than 5,000 ATLAS systems worldwide Patented surface reconstruction Easy to use Delegate topography to staff Reproducible results independent of operator technique

of corneas expected in clinical practice Superior alignment through triangulation with patented Cone-of-

4 ATLAS Placido Disk Technology Ideal Placido disk design means reliable results for a wide range of patients Large diameter, closely spaced rings minimizes ring jam found in smallcone systems Optimized for the range of corneas expected in clinical practice Superior alignment through triangulation with patented Cone-of- Focus Removes axial positioning uncertainty Enables automatic correction of operator focus and positioning error

5 Accuracy via the Arc-Step Method Arc-Step Method Throws a net over cornea, reconstructing cornea where net intersects itself Ensures accurate transition from ring to ring Minimal residual error Only the ATLAS performs multiple iterations of triangulation (the Van Saarloos Variant) to minimize any residual error

Designed for Practitioner and Patient Easy to use Long working distance (70 mm) is less sensitive to alignment error Comfortable for the patient Does not enter patient s orbit

6 Designed for Practitioner and Patient Easy to use Long working distance (70 mm) is less sensitive to alignment error Comfortable for the patient Does not enter patient s orbit Non-visible infrared (IR) ring illumination for increased patient comfort and corneal coverage Unique chinrest positions patient for wide peripheral coverage and automatically detects OD/OS

13 Clinical Applications of ATLAS Corneal Topography

Detect and Manage Pathology Axial map reveals a displaced corneal apex and inferior steepening, which standard keratometry at 3 mm would have missed.

14 Detect and Manage Pathology Axial map reveals a displaced corneal apex and inferior steepening, which standard keratometry at 3 mm would have missed. Irregularity map, relative to a best-fit ellipsoid, highlights surface irregularities that may limit bestspectacle corrected visual acuity. Elevation map shows a 29 micron protrusion above a best-fit reference sphere. Mean Curvature map eliminates corneal astigmatism, highlighting underlying features, such as this cone peak.

Track Corneal Health for Improved Care Axial map reveals inferior steepening and corneal warpage from years of wearing an improperly fit RGP contact lens with a highly aspheric back surface.

15 Track Corneal Health for Improved Care Axial map reveals inferior steepening and corneal warpage from years of wearing an improperly fit RGP contact lens with a highly aspheric back surface. The cornea was allowed to normalize over approximately 4 months and returned to a normal appearing astigmatic shape. Image simulation displays higher-order corneal aberrations and confirms patient s complaints of severe spectacle blur. Image simulation shows the improvement in visual acuity with a reduction in higher-order aberrations.
