Scientists from Bar-Ilan University’s Institute of Nanotechnology and Advanced Materials, in Tel Aviv, Israel, have developed eye drops from nanoparticles that can repair impaired corneas to improve vision
Team of research scientists along with ophthalmologist Dr. David Smadja from Shaare Zedek Medical Center and Bar-Ilan University have developed novel eye drops from nanoparticles. As a part of study, researchers have tested these drugs on impaired cornea of pig. The drug effectively improved defected short-sightedness and long-sightedness. The team will be conducting human clinical trials by the end of 2018. “These nanoparticles go into the shallow ablated patterns generated on the surface of the cornea,” said Zeev Zalevsky, professor of electrical engineering and nanophotonics at Bar-Ilan University. “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.”
Researchers believe that this novel eye drop has potential to eliminate need for eye glasses. These nanodrops can revolutionize ophthalmological treatments of patients suffering from myopia (nearsightedness), hyperopia (farsightedness) and other refractory conditions. Also, it can replace multifocal lenses, which can allow individual to visualize objects from various distances. However, further research is required to get clarity regarding how many of these nanodrops would be required to repair the cornea to the point where eyeglasses are no longer required. Moreover, treatment cost for the same is important factor.
According to the Jerusalem Post, “patients would open an application on their smartphone, measure their eye refraction at home, create a laser pattern and then laser corneal stamping of an optical pattern onto the corneal surface of their eyes. This has already been done successfully on fresh pig eyes. Drops with a synthetic nanoparticles solution can correct the vision problem.”
