Based on her observations and research, Dr. Bath conceived the idea for a laser-based device that could vaporize cataracts and irrigate the eye, making cataract surgery safer, more precise, and less painful.

Dr. Bath dedicated significant time and resources to developing a working prototype of the Laserphaco Probe. This involved collaboration with engineers and other scientists to translate her concept into a tangible device.

Dr. Bath secured her first patent for the Laserphaco Probe in Japan (Japanese Patent No. 2020118), recognizing the novelty and utility of her invention in the international arena.

She was granted a U.S. patent (U.S. Patent No. 5,445,614) for the Laserphaco Probe, solidifying her intellectual property rights in the United States.

Dr. Bath obtained a European patent (European Patent No. EP0375633B1) for the Laserphaco Probe, extending the protection of her invention to multiple countries within Europe.

Following the patents, Dr. Bath continued to advocate for the use of laser technology in cataract surgery and worked on refining and improving the Laserphaco Probe design. She also worked on less expensive methods to bring the procedure to underserved communities.
