Dr. Bath's invention was called the Laserphaco Probe (1986). “Harnessing laser technology, the device created a less painful and more precise treatment of cataracts.” Bath received a patent for the device in 1988, becoming the first African American female doctor to receive a patent for a medical purpose. In 1976, Bath co-founded the American Institute for the Prevention of Blindness, which established that "eyesight is a basic human right." She was also the first African-American woman to serve on staff as a surgeon at the UCLA Medical Center.
