Israeli researchers are on the verge of creating a way to improve eyesight – negating the need for eyeglasses or contact lenses in some cases – all by using a smartphone and eye drops. Writers at The Times of Israel tell us more:
The first step requires patients to measure their eyesight via their smartphones. There are already a number of apps that do this, said Smadja [an ophthalmologist and codeveloper of Nano-Drops]. The second step requires the patients to use a second app — being developed by the researchers — which would have a laser device clipped onto the smartphone. This device will deliver laser pulses to the eye in less than a second that etch a shallow shape onto the cornea to help correct its refractive error. During the last stage, the Nano-Drops — made up of nontoxic nanoparticles of proteins — are put into the eye and they activate the shape, thus correcting the patients’ vision.
“It’s like when you write something with fuel on the ground and the fuel dries up, and then you throw a flame onto the fuel and the fire takes the shape of the writing,” Smadja explained. “The drops activate the pattern.”
