Breakthrough technology offers new hope to people with glaucoma, retinitis and macular degeneration

In January 2009, the life of engineer Michel Meunier, a professor at Polytechnique Montréal, changed dramatically. Like others, he had observed that the extremely short pulse of a femtosecond laser (0.000000000000001 second) could make nanometer-sized holes appear in silicon when it was covered by gold nanoparticles.
