Doctor Patricia Bath, an ophthalmologist from New York, was living in Los Angeles when she received her first patent, becoming the first African American female doctor to patent a medical invention. Patricia Bath’s patent (#4,744,360) was for a method for removing cataract lenses that transformed eye surgery by using a laser device making the procedure more accurate.
Patricia Bath’s passionate dedication to the treatment and prevention of blindness led her to develop the Cataract Laserphaco Probe. The probe patented in 1988, was designed to use the power of a laser to quickly and painlessly vaporize cataracts from patients’ eyes, replacing the more common method of using a grinding, drill-like device to remove the afflictions. With another invention, Bath was able to restore sight to people who had been blind for over 30 years. Patricia Bath also holds patents for her invention in Japan, Canada, and Europe.
