Soft contact lenses eyed as new solutions to monitor ocular health conditions

WEST LAFAYETTE, Ind. - New contact lens technology to help diagnose and monitor medical conditions may soon be ready for clinical trials.
A team of researchers from Purdue University worked with biomedical, mechanical and chemical engineers, along with clinicians, to develop the novel technology. The team enabled commercial soft contact lenses to be a bio instrumentation tool for unobtrusive monitoring of clinically important information associated with underlying ocular health conditions.
The team's work is published in Nature Communications. The Purdue Research Foundation Office of Technology Commercialization helped secure a patent for the technology and it is available for licensing.
"This technology will be greatly beneficial to the painless diagnosis or early detection of many ocular diseases including glaucoma" said Chi Hwan Lee, the Leslie A. Geddes assistant professor of biomedical engineering and assistant professor of mechanical engineering at Purdue who is leading the development team. "Since the first conceptual invention by Leonardo da Vinci, there has been a great desire to utilize contact lenses for eye-wearable biomedical platforms."
