Inventor of Laser-Based Cataract Treatment Dies at 76

Patricia Bath was the first African American surgeon at UCLA Medical Center.

Retired UCLA ophthalmologist Patricia Bath, an inventor whose research on lasers advanced cataract surgery, died on May 30, The Scientist reports. Bath was the first African American surgeon at the UCLA medical center and co-founded the American Institute for the Prevention of Blindness.

“I had a few obstacles but I had to shake it off,” Bath told ABC News last year. “Hater-ation, segregation, racism, that’s the noise you have to ignore that and keep your eyes focused on the prize, it’s just like Dr. Martin Luther King said, so that’s what I did.”

Bath was born in Harlem. Her father worked for the New York City subway system, and her mother was a domestic worker. She graduated from Howard University’s medical school and then worked as an intern at Harlem Hospital and Columbia University, according to a biography published by the National Library of Medicine (NLM).

She noticed a large discrepancy in the rates of blindness between the majority-black patients at Harlem and majority-white patients at Columbia. She conducted an epidemiological study that found the rate of blindness among the black population was twice that of whites.

Bath joined the UCLA medical center in 1974. In 1983, she became chair of its ophthalmology residency program. In the 1980s, Bath began researching the use of lasers in eye treatments, and in 1988, she patented the Laserphaco Probe, a device that removes cataracts.
