Blum was working with Rangaswamy and James Wynnne at IBM’s T.J. Watson Research Center when they observed the effect of the ultraviolet excimer laser on biological materials. They investigated further and they found that the laser made clean, precise cuts that would be ideal for delicate surgery.
Millions of people throughout the world have achieved improved eyesight through LASIK (Laser-Assisted in Keratomileusis). This surgery helped people discard their eye glasses and contacts. The procedure uses an ultraviolet excimer laser to reshape the cornea without damaging the surrounding tissue.
