What impact of patricia bath's invention has on society?

She invented a device to make surgery on the eyes of cataract patients better and less painful, With her Laserphaco Probe, Bath was able to help restore the sight of individuals who had been blind for more than 30 years. Most patients that need this treatment are older folks that were dependent on other people, but now can continue to lead independent lives. Pretty neat, huh? Way to go, Dr. Bath.
