Contact Lens Uses Microfluidics to Monitor and Treat Glaucoma
Summary
IEEE Spectrum reports a soft, electronics-free smart contact lens that uses microfluidics to monitor intraocular pressure and automatically deliver glaucoma medication. The device reads pressure via a microchannel-based sensor and a smartphone CNN for readouts, with drug reservoirs that release therapy when needed; tests show promising biocompatibility and up to two weeks of wear, though continuous monitoring relies on a smartphone and there are trade-offs with an electronics-free design.
