  1. Early Results of Static and Dynamic Iris Tracking for Moderate and High Astigmatism in LASIK Patients Michael J. Endl, M.D. The author of this poster has no financial interest in the subject matter of this poster.

  2. Early Results of Static and Dynamic Iris Tracking for Moderate and High Astigmatism in LASIK Patients Presented by Michael J. EndlMD Fichte-Endl, & Elmer Eye Associates ASCRS 2011

  3. Early Results of Static and Dynamic Iris Tracking for Moderate and High Astigmatism in LASIK Patients Moderate to High Astigmatism • n=265 • 126 eyes between 0.75 to 1.5 D Cylinder • 139eyes > 1.5 D Cylinder

  4. Wavefront Guided and Standard Treatments Zyoptix = 190 eyes Planoscan= 75 eyes

  5. Key-Values of Combined Data Sets Spherical Equivalent [Dpt] Wavefront & Standard Sphere [Dpt] Wavefront & Standard

  6. Cylinder Key Data Cylinder [Dpt] Wavefront & Standard, Moderate & High Astigmatism

  7. Moderate and High Astigmatism Key Data Sets Wavefront & Standard, Moderate Astigmatism 0.75 – 1.5 D Cylinder • Wavefront & Standard, High Astigmatism >1.5 D Cylinder

  8. Data Sets by Treatment Type Zyoptix Cylinder Values PlanoscanCylinder Values

  9. Combined Wavefront & Standard n=265

  10. Combined Wavefront & Standard n=265

  11. Combined Wavefront & Standard n=265

  12. Wavefront & Standard

  13. Wavefront & Standard

  14. n-265 Wavefront & Standard

  15. n=265 Wavefront & Standard

  16. Wavefront & Standard ** Remainder of eyes had between 0-5 degrees of dynamic rotation.

  17. Conclusions A significant degree of both static and rotational cyclotorsion occurs in eyes undergoing myopic refractive surgery. The newly FDA approved static and active tracking system on the Technolas 217z excimer provides safe and accurate outcomes for the treatment of both moderate and high amounts of refractive astigmatism, for both wavefront driven and standard excimer treatments.
