2  Collectively we have performed > LASIK, LASEK and PRK procedures  All surgery performed by AC or RC  WaveLight Allegretto 200, 400 & 500 Hz lasers  Hansatome, XP, Rondo, WaveLight FS200  This paper is made up of a collection of papers that have been presented over the past few years

3 In myopia < LASIK and ASA (Advanced Surface Ablation) provide very similar outcomes In myopia > LASIK provides better and more stable outcomes A great percentage of eyes gain lines of BCVA in the higher myopia group LASIK outperforms ASA for hyperopia

19 Primary treatments have better safety profiles than secondary treatments Enhancement surgery has a very high success rate in terms of improving UCVA It does however lead to more loss of lines of BCVA than the primary procedure This is true for myopia & hyperopia as well as LASIK and ASA “Get it right the 1 st time” has merit

20 LASIK 6 Months 7.2% of Myopic LASIK eyes lose 1 or more lines of BCVA while 15.7% of LASIK Enhancement eyes lose 1 or more lines of BCVA. 1.1% of enhancement eyes lose >2 lines of BCVA which very comfortably meets the FDA requirements of a safe procedure (less than 5% should lose >2 lines) Enhancements 6 Months

21 6.9% of Myopic LASEK eyes lose 1 or more lines of BCVA while 9.8% of LASEK Enhancement eyes lose 1 or more lines of BCVA. 0.3% of LASEK eyes lose >2 lines of BCVA which very comfortably meets the FDA requirements of a safe procedure (less than 5% should lose >2 lines) LASEK 6 MonthsEnhancements 6 Months

22 The WaveLight Allegretto offers the widest range of refractive tools in the form of: WaveFront Optimised treatments WaveFront-Guided treatments Topography-Guided profiles (2 modes) Asphericity-Guided profiles Ray-Tracing profiles

23  85% receive WFO treatments  15% receive customized treatments  How do they compare?

24  Compare 4 profiles across all refractive errors  WFO  WFG  T-CAT  Custom-Q

25 WFO WFG Topography-Guided Custom-Q

26  European Multicentre Trial completed  3 Centres (Zurich, Cologne, Dublin)  132 Eyes treated, 111 with full follow-up  Ray Tracing was only done on Primary treatments in this clinic trial  All eyes > myopia or > 2.00 DC

27 WFO WFG T-CAT RT WFOWFG Topography-Guided RT

28  75% receive WFO treatments  25% receive customized treatments  How do they compare?  RT not used in this cohort in this study

30  LASIK and ASA have proven to be very effective and safe  LASIK better than ASA in high myopia / hyperopia  Primary treatments safer than Secondary treatments  Different profiles have different applications  Ray Tracing promises to get closer to the “holy grail”
