’98 ASCRS SURVEY CONCLUSIONS LASIK is the fastest growing refractive procedure amongst ASCRS U.S. surgeons High volume refractive surgeons prefer LASIK over PRK Bilateral same OR visit surgery is accepted and preferred for LASIK > RK > PRK VisX Star preferred 3:1 over all other lasers Hansatome is the preferred microkeratome DUFFEY 1999
