Drug-primed contact lenses could deliver medicine more safely and effectively than eyedrops, researchers have reported. At the national meeting of the American Chemical Society, researchers described a process for manufacturing soft contact lenses containing timed-release capsules for drug delivery. The medicine is encapsulated in oil-based nanoparticles so small they are invisible to the eye and will not cloud the lenses.
Eye diseases like glaucoma could one day be treated by pharmaceuticals delivered through contact lenses. Chemical engineers from the University of Florida say they've been able to make soft contact lenses containing tiny embedded particles that slowly release drugs directly where they're needed. The research was presented today at the 225th national meeting of the American Chemical Society, the world's largest scientific society, held this week in New Orleans.
