Nanoparticle eyedrops could eliminate the need for glasses


Researchers from the Shaare Zedek Medical Center and Bar-Ilan University just released a reportexplaining how a new type of eyedrop infused with “nanoparticles” could replace the need for glasses or contacts. It’s a bit complicated, and requires a brief doctor visit, but it apparently works like a charm.
The three-step process starts with a measurement of the individual’s eye refraction, which can be performed with a smartphone. Then, doctors create a very specific laser pattern which is applied to the eye for less than one second. The laser creates tiny grooves in the surface of the cornea. Lastly, special eyedrops are applied.

“These nanoparticles go into the shallow ablated patterns generated on the surface of the cornea,” Zeev Zalevsky explained to Digital Trends. “They change the refraction index inside of those patterns. This corrects the visual problem the user has. The process of correction can be done at home without the need of a medical doctor.”

The procedure is less invasive than traditional laser eye surgery in that it only affects the exterior of the eye and does not require an extensive procedure. However, because the alterations to the eye are so minor, the tiny etchings in the cornea eventually heal themselves and vision subsequently degrades. The researchers believe the positive effects of the treatment will last one to two months.
