Indiana University School of Optometry is delighted to share the below press release from Purdue University. IUSO’s Director of the Borish Center for Ophthalmic Research Pete Kollbaum, BS’97, OD’99, PhD’07, is leading the clinical trials on new contact lens technology. The Borish Center for Ophthalmic Research supports the research endeavors of the School of Optometry and welcomes collaborative partners from private practice, universities, industry, and private agencies to join together to work on important questions related to vision science.
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 bioinstrumentation 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, Purdue’s Leslie A. Geddes assistant professor of biomedical engineering and assistant professor of mechanical engineering, 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.”
Sensors or other electronics previously couldn’t be used for commercial soft contact lenses because the fabrication technology required a rigid, planar surface incompatible with the soft, curved shape of a contact lens.
The team has paved a unique way that enables the seamless integration of ultrathin, stretchable biosensors with commercial soft contact lenses via wet adhesive bonding. The biosensors embedded on the soft contact lenses record electrophysiological retinal activity from the corneal surface of human eyes, without the need of topical anesthesia that has been required in current clinical settings for pain management and safety.
“This technology will allow doctors and scientists to better understand spontaneous retinal activity with significantly improved accuracy, reliability and user comfort,” said Pete Kollbaum, director of the Borish Center for Ophthalmic Research and an associate professor at Indiana University School of Optometry, who is leading clinical trials.
The other members of the team are Bryan Boudouris, a professor of chemical engineering from Purdue, and Baoxing Xu, an associate professor of mechanical and aerospace engineering from the University of Virginia.
This work is funded by the National Science Foundation (NSF CMMI-1928784 & 1928788) and the Air Force Office of Scientific Research (AFOSR FA9550-19-1-0271). For more information about licensing opportunities, contact Patrick Finnerty of OTC at firstname.lastname@example.org.
