Among many firsts, Patricia Bath is the first African American to complete a residency in ophthalmology and the first African-American female doctor to receive a medical patent. She invented the Laserphaco Probe for cataract treatment in 1986.
Born in Harlem, New York, on November 4, 1942, Patricia Bath became the first African American to complete a residency in ophthalmology in 1973. Two years later, she became the first female faculty member in the Department of Ophthalmology at UCLA’s Jules Stein Eye Institute. In 1976, Bath co-founded the American Institute for the Prevention of Blindness, which established that “eyesight is a basic human right.” In 1986, Bath invented the Laserphaco Probe, improving treatment for cataract patients. She patented the device in 1988, becoming the first African-American female doctor to receive a medical patent.
…Through her studies there, she discovered that African Americans were twice as likely to suffer from blindness than other patients to which she attended, and eight times more likely to develop glaucoma. Her research led to her development of a community ophthalmology system, which increased the amount of eye care given to those who were unable to afford treatment.
