Contact lenses that can provide glaucoma treatment

International researchers have developed contact lenses that are said to be able to treat glaucoma by determining when treatment is needed and applying it.

The device is flexible and battery-free, with a compact design and could be a promising system for treating glaucoma, according to researchers. While more research is needed, the team says this device may one day be manufactured cost-effectively. Glaucoma and related diseases can cause irreversible vision loss, and the damage is often caused by increased intraocular pressure due to abnormal fluid circulation in the eye.

This pressure can vary depending on human activity and circadian rhythm, making treatment difficult as it requires long-term and continuous monitoring of the eye condition. Terrorist devices, which combine therapy and diagnosis, are able to monitor the determined condition and apply appropriate treatment.

Xi Xie, Cheng Yang and his colleagues have developed a terrorist contact lens that uses electric sensing to measure intraocular pressure and can deliver medication on demand. The device was tested in the eyes of pigs and rabbits and was able to detect changes in intraocular pressure. When the measured intraocular pressure reaches a high level of risk, the drug delivery module (powered by wireless power transmission) has the ability to start the delivery of antiglaucoma drug to the anterior chamber of the eye through the corneal barriers.

The authors believe that the manufacture of the device is compatible with existing large-scale and cost-effective production processes. However, they suggest that more research is needed before clinical trials can proceed.
