A team of researchers at Sun Yat-Sen University has developed a contact lens that can be used to monitor changes in intraocular pressure and give glaucoma medication when need.
Glaucoma is damage to the optic nerve due to pressure on part of the eye, resulting in partial or complete blindne.
The lens is double layered with an air pocket between the laye.
This design includes brimonidine micromodules placed along its edges in a setting that does not obstruct visi.
So far, the researchers have tested their contact lens in rabbits and pigs and found that it is able to continuously monitor intraocular pressure changes and deliver the drug when need.
