  1. Analysis of Ophthonix vs. LASIK vision correction March 8, 2005

  2. Ophthonix Wavefront-guided Eyeglasses = New method of vision correction using similar technology as LASIK surgical correction However, the laser doesn’t tailor-cut your eyes, but is used to etch customized eyeglasses to correct your specific eye aberrations

  3. Agenda • Introduction to 2’00” Ophthonix Wavefront-Guided Corrective Technology • Movie: “Eye-Wars: Return of the Eyeglasses” 7’00” Explain vision optimization process with: - Eyeglasses - LASIK surgical correction - Ophthonix Wavefront correction • Statistical Analysis of Contrast / Visual Acuity Studies3’00” Ophthonix vs. Current Corrective Technologies

  4. Ophthonix Wavefront-guided lenses combine all of these legacy technologies! Ophthonix Wavefront-guided eyeglasses is the latest technology in vision optimization … Eyeglasses(ja-gillion years ago) OphthonixWavefront-GuidedLenses (2005) Radial Keratotomy(~1960s) LASIK (~1990s) PRKPhotorefractive Keratotomy(~1987)

  5. THE PROBLEM WITH TODAY’S TECHNOLOGY: Matching an “imperfect” eye to a “perfect” lens Today’s Perfect Lens Imperfect Eye Mismatch! “All of the idiosyncrasies and aberrations of the eye can’t be corrected by a standardized lens!”

  6. THE SOLUTION TO THIS PROBLEM: Matching an “imperfect” eye to an “imperfect” lens Customized to “Optical Eyeprint” Imperfect Eye Bingo! We have a match “Customize a lens to correct for all these aberrations, matching the lens to the individual’s optical eyeprint!”

  7. Effectiveness of a vision correction technology measured by well it corrects visual aberrations … Halos Comets Starbursts “Optimized Vision”

  8. Aberrations can be described mathematically by Zernike’s polynomials … and …

  9. And … our ever-popular Point-Spread Functions!

  10. The Ophthonix Z-View Aberrometer uses these to quantify aberrations which are used to create custom lenses … It has at least 10x resolution than aberrometers used in LASIK correction!

  11. Now … the movie!

  12. Analysis of Performance of Wave-front Guided Lenses:There are three groups of test subjects … Test Subjects Emmetropes (Normal) LASIKs Myopes (“nearsighted”) Experiment Placebo lenses No lensesRx lenses vs. vs. vs. “Ophthonix Z-lens” Wavefront-guided lensesGroup-Size (n) 27 5 13

  13. Analysis of Performance of Wave-front Guided Lenses:Emmetropes • Example of One Emmetrope Subject - Contrast Visual Acuity Test • Emmetrope Paired Student’s T-Test Statistically significant differences between Z-lens and placebo lens for:- visual acuity,- low contrast visual acuity,- mid-frequency contrast sensitivity! *Ophthonix Corp. test data.

  14. Analysis of Performance of Wave-front Guided Lenses:LASIK patients • Example of One LASIK Subject - Contrast Visual Acuity Test *Placebo is not wearing corrective lenses (though eyes have had LASIK correction). *Ophthonix Corp. test data.

  15. Analysis of Performance of Wave-front Guided Lenses:Myopes • Example of One Myope Subject - Contrast Visual Acuity Test • Myope Paired Student’s T-Test Statistically significant differences between Z-lens and Rx lens for:- - visual acuity, - low contrast visual acuity, - mid- and high- frequency contrast sensitivity! *Ophthonix Corp. test data.
