Arthur Cummings, Richard Corkin Wellington Eye Clinic UPMC Beacon Hospital, Dublin ICO Cavan, 12 th May 2011
Collectively we have performed >30 000 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
In myopia < -8.00 LASIK and ASA (Advanced Surface Ablation) provide very similar outcomes In myopia > -8.00 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
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
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
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
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
85% receive WFO treatments 15% receive customized treatments How do they compare?
Compare 4 profiles across all refractive errors WFO WFG T-CAT Custom-Q
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 > -4.00 myopia or > 2.00 DC
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”
