Soon, the lens will not only improve vision, but also to treat the eye. Created a contact lens, which is produced in the eyes of doses of drugs to treat diseases such as glaucoma.
Most treatments for eye diseases using a drop, but a significant amount of the drug quickly, "slipping away" from the eye, often draining into the nasal cavity and then entering the bloodstream, resulting in unnecessary medication and side effects. Fluid from the transparent material and created a contact lens.
If the drug is soluble in water, it is "bogged down" in the network of tiny water-filled channels in the material - if not, the drug will fall into a "trap" within the matrix of polymer nanotechnology and from there fall into the channels. In contact with the fluid of the eyeball, these channels open and release the drug.
While the lenses were tested only in the lab: Scientists have used a water-soluble drug to treat glaucoma and insoluble antibiotic. They found that can accurately control the release of drugs over several hours or even days.
