2008 ASCRS SUMMARY • Volume of LVC (U.S.) in 2008: 0.988 M eyes. 11-12 M since 1996. • P-IOL(40%) and LASIK (23%) in high myopes. • VisX still at > 3:1 (73%) over all other lasers combined. • Greater than 30% penetration of modern refractive surgery amongst refractive surgeons (no data on surgeon family members this year). • 83% (stable) use MMC for prophylaxis/haze. Duffey 2008
2008 ASCRS SUMMARY • Most desired flap thickness is 120-130 microns. 100 micron flap thickness is favored by 20% of surgeons (up from 11% three years ago). • 14% of respondents are OK with bilateral P-IOL (11% two years ago) and 5% with RLE at the same surgical setting. • ReStor(15%) and CrystaLens (14%) accommodative IOL’s are gaining popularity while the ReZoom (3%) is dropping off as lens-based presbyopia options.
