iTrace Dynamic Laser Refraction: Clinical Application Joe S. Wakil, M.D. Chairman, Tracey Technologies, LLC and EyeSys Vision, Inc. Speaker has a Financial Interest

Why Dynamic Ray Tracing? Because… the Eye is NOT a Telescope! Pupil Size: Accommodation: Tear Film: Effects Refraction (ex. Night Myopia) Refraction is NOT a FIXED Number! Effects Refraction (Instrument Myopia) Effects Quality of Vision (Aberrations) Where are the Sources of Aberrations? How do they change with Surgery? Cornea: Lens: Astigmatism (Irreg.), Sph & other HOA Astigmatism, Coma & other HOA

Aberrometer/Wavefront Technologies Hartmann-Shack Lenslet Array Tscherning Aberrometer Differential Skiascopy Ray Tracing Features: -Rapid, point by point, IR measurement - no data confusion -Pupillometry with auto-tracking/capture -Programmable sampling (256 pts.) in any pupil up to 8mm -Open Field Fixation – avoid instrument myopia and measure Accommodation -Corneal Topography integration – able to measure Lens Aberrations -VISX license for Custom LASIK

Advantages of Ray Tracing Aberrometry Combined with Corneal Topography - iTrace Robust dynamic range to measure highly irregular eyes including immediately post-op Multi-Zone Refraction in seconds to measure variations in refraction from normal night myopes to post-op results saving chair time Able to separate Corneal from Lenticular (internal ocular) sources of aberrations with EyeSys Corneal Topography Improved Diagnostic Wavefront to help in patient selection including Custom LASIK and IOL procedures - Thank You For Your Attention -

Conclusion The Tracey iTrace brings a new standard of care in completely assessing vision in terms of quality of vision and corneal topography to progress visual correction through surgery to its ultimate goals.
