Eyedrops improve vision of pigs, could replace glasses
Israeli ophthalmologists have patented eyedrops, said to heal damaged corneas and improve both short-sightedness and long-sightedness in tests on pigs. As human trials are expected to begin later this year, researchers hope they could eliminate the need for eyeglasses. Prospective patients could use a smartphone app to scan the eyes and use the 'nanodrops' accordingly, said researchers.
