Diabetic patients need to measure their blood-sugar level by drawing blood before and after a meal and it is easy to develop complications due to diabetes. Recently, a research team from POSTECH developed technology that allows diagnosis of diabetes and treatment of diabetic retinopathy just by wearing 'Smart Light-emitting diode (LED) Contact Lens.' With this technology, it is anticipated that development of wearable diagnostic and therapeutic devices for diabetes will be vitalized.
Professor Sei Kwang Hahn and his research team including his PhD student, Geon-Hui Lee, invented a smart photonic contact lens and a wearable medical device which can diagnose diabetes and treat diabetic retinopathy. Their new research results on photonic diagnosis and photonic therapy of diabetes are published on-line in the world's renowned journal, Nature Reviews Materials , as of January 7 th in collaboration with the research group led by Zhenan Bao from Department of Chemical Engineering at Stanford University and David Myung from Stanford Medicine Ophthalmology.
The research team successfully developed a smart contact lens with integrated micro LED and photodetector which can measure glucose concentration in the conjunctival blood vessels by analyzing the NIR light. With this development, they succeeded in diabetic diagnosis.
Furthermore, they put their new smart LED contact lenses on rabbit eyes with diabetic retinopathy disease and irradiated light repeatedly for a month. As a result, they confirmed that there was significant reduction of angiogenesis (production of new blood vessels) in retina and verified clinical feasibility of the smart LED contact lens for the diabetic retinopathy therapy.
