The lenses could be used to deliver eye drops for glaucoma and cataracts, as well as less serious problems such as dry eyes, inflammation, and bacterial infections.
The problem with eye drops is that only a small amount (1 to 5 percent) of the drug actually gets to the cornea – a clear film covering the iris – the place it needs to go to do its job, said Anuj Chauhan, professor of chemical engineering at the University of Florida.
