POSTECH research team led by Professor Sei Kwang Hahn proposes a new paradigm for monitoring and control of intraocular pressure in glaucoma patients.
Glaucoma is a common ocular disease in which the optic nerve malfunctions due to the increased intraocular pressure (IOP) caused by drainage canal blocking in the eye. This condition narrows the peripheral vision and can lead to vision loss in severe cases. Glaucoma patients have to manage IOP levels for their lifetime. Automatic monitoring and control of the IOP in these patients would significantly improve their quality of life.
Recently, a research team at POSTECH has developed a smart contact lens by combining an IOP sensor and a flexible drug delivery system to manage IOP measurement and medication administration.
