"Smart" contact lenses that can cut visits to doctor New York (PTI): "Smart" contact lenses that measure pressure within the eye and dispense medication accordingly could be made possible using a new material developed by biomedical engineers at University of California. Tingrui Pan, assistant professor of biomedical engineering, and postdoctoral researcher Hailin Cong started with a material called polydimethylsiloxane (PDMS).
They developed a method for placing powdered silver on the PDMS in a precise pattern, to create conductive wires. The silver also has antimicrobial properties. The researchers say they were able to shape the PDMS-silver into a contact-lens shape and show that it could function as a simple pressure sensor. Glaucoma, in which drainage of fluid that delivers nutrients and removes metabolic waste is blocked, is a leading cause of blindness worldwide. A contact lens that could continuously measure pressure within the eye and relay the data to a computer would allow doctors to learn more about glaucoma and improve patient treatment. The researchers plan to apply for approval to begin trials of the lenses in humans, Pan said. ________________________________ Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.
