Researchers have developed a smart contact lens by combining an IOP sensor and a flexible drug-delivery system to manage IOP measurement and medication administration. The wireless theranostic smart contact lens monitors and controls intraocular pressure in glaucoma.
The smart contact lens uses hollow nanowires made of gold. It is integrated with a flexible drug-delivery system, wireless power and communication system, and an application-specific integrated circuit chip for both monitoring and control of IOP in glaucoma. Notably, the IOP sensor has exhibited high sensitivity to ocular strain, excellent chemical stability, and biocompatibility. Furthermore, the flexible drug-delivery system can provide on-demand delivery of timolol for IOP control.
The researchers successfully demonstrated that the theranostic smart contact lens enabled the IOP measurement in real time and the appropriate amount of drug release to match the degree of IOP in rabbits with glaucoma.
