That’s it!

Dr. Patricia Bath, an ophthalmologist and laser scientist, was not only the first female African-American doctor to patent a medical device but also the first person to invent a surgery that greatly advanced treatment for cataracts. Dr. Bath invented the Laserphaco Probe in 1981 which used lasers to treat cataracts more precisely and less painfully. The invention was able to recover vision for people who had been blind or vision impaired for decades.
