Patricia Bath was an American ophthalmologist and humanitarian who invented the Laserphaco Probe for cataract surgery, becoming the first African-American female doctor to receive a medical patent and restoring sight to thousands worldwide.
Patricia Era Bath was born in Harlem, New York City, on November 4, 1942. Inspired by Dr. Albert Schweitzer’s medical service, she earned her Bachelor of Science in chemistry from Hunter College in 1964 and her Medical Degree with honors from Howard University College of Medicine in 1968. She completed a residency in ophthalmology at New York University from 1970 to 1973—becoming the first African-American resident in ophthalmology at the institution.
During her training at Harlem Hospital and Columbia University, Bath noticed that blindness was twice as prevalent among Black patients compared to white patients due to lack of access to ophthalmic care. This prompted her to create a new discipline: "community ophthalmology," which combined epidemiology, public health, and clinical eye care to bring preventative vision screenings directly into underserved communities. In 1976, she co-founded the American Institute for the Prevention of Blindness, declaring that "eyesight is a basic human right."
In 1981, Bath conceived a breakthrough surgical device using laser technology to dissolve cataracts quickly and painlessly. Her invention, the Laserphaco Probe, was patented in 1988 (U.S. Patent No. 4,744,360), making her the first African-American female doctor to secure a medical patent. Her innovative technique restored sight to individuals who had been blind for over thirty years. In 1983, she became the first woman to chair an ophthalmology residency program in the United States at the UCLA Medical Center. Bath was posthumously inducted into the National Inventors Hall of Fame in 2022.
