When she first conceived of the device in 1981, her idea was more advanced than the technology available at the time. It consists of an optical laser fiber surrounded by irrigation and aspiration (suction) tubes.

She received a patent for the device in 1988, becoming the first African-American female doctor to receive a patent for a medical purpose. What inspired patricia bath to invent the lasrphaco probe? Later she named it the Laserphaco Probe.

It took her nearly five years to complete the research and testing needed to make it work and apply for a patent. (She also holds patents in Japan, Canada and Europe.) The patent that she received for this invention made her the first African American woman to receive a patent for a medical device.
A graduate of Hunter College and Howard University College of Medicine, Bath was the first female ophthalmology faculty member at the David Geffen School of Medicine at … In 1993, Bath retired from her position at the UCLA Medical Center and became an honorary member of its medical staff.
She is an American, born in Harlen, New York in November 1942. With her Laserphaco Probe, Bath was able to help restore the sight of individuals who had been blind for more than 30 years.

In 2000, she was granted a patent for a method she devised for using ultrasound technology to treat cataracts. Patricia Bath is the first African American female doctor to receive a patent for a medical invention, the laserphaco probe. The laser energy vaporizes or "phacoblates" the cataract and lens matter within a few minutes. We need you to answer this question! Patricia Bath, MD, the inventor of the Laserphaco probe and the first black female doctor to patent a medical invention, died from complications from cancer May 30 at the age of 76, according to a Washington Post obituary.

She patented the device in 1988, becoming the first African-American female doctor to receive a medical patent (she also holds patents in Japan, Canada, and Europe.). In 1981, Dr. Bath began working on her most well-known invention: the Laserphaco Probe. Harnessing laser technology, the device created a less painful and more precise treatment of cataracts. The Laserphaco Probe significantly increased the accuracy and results of cataract surgery, which had previously been performed manually with a mechanical grinder. This device is a specialized tool and procedure that is used to remove cataracts. Her interest, experience, and research on cataracts lead to her invention of a new device and method to remove cataracts—the laserphaco probe. Three of Bath’s four patents relate to the Laserphaco Probe. The laser probe can be inserted in a tiny (1 mm) incision in the eye.
