Patricia Era Bath is an American ophthalmologist, inventor, and humanitarian. Bath co-founded the American Institute for the Prevention of Blindness in 1978, for which she served as president. In 1983, she became the head of a residency in her field at Charles R. Drew University of Medicine and Science, the first woman ever to head such a department. She served as a professor of Ophthalmology at Howard University's School of Medicine and as a professor of Telemedicine and Ophthalmology at St. George’s University. She conceived of the Laserphaco Probe, a medical device that improves on the use of lasers to remove cataracts in 1981. The device was completed in 1986 and patented in 1988 making her the first African-American female doctor to receive a patent for a medical purpose. Bath has improved the device over the years and has successfully restored vision to people who had been unable to see for decades. In 2000, she was granted a patent for a method she devised for using ultrasound technology to treat cataracts. She’s amazing.
