Femtosecond laser, keratome provide similar results
May 1st 2006Palo Alto, CA-A prospective comparison study of the IntraLasefemtosecond laser (IntraLase Corp.) and the Hansatome keratome(Bausch & Lomb) in myopic LASIK with VISX CustomVue (AdvancedMedical Optics) showed that both devices produced excellent visualoutcomes.
