A smart contact lens developed by researchers at South Korea's Pohang University of Science and Technology can monitor intraocular pressure (IOP) in glaucoma patients and deliver medications in response to IOP levels.
The smart contact lens integrates an IOP sensor that incorporates a flexible drug delivery system with gold nanotubes, a wireless power and communication system, and an application-specific integrated circuit (ASIC) chip.
In tests on rabbits with glaucoma, the researchers found the device could measure IOP in real time and deliver timolol on demand in a dosage that matched the degree of IOP detected.
