Scientists from the University of Waterloo have developed a nanoparticle-based topical solution to combat dry eyes with a single weekly application.

Patients currently have to administer a solution three times a day to reduce pain and irritation. The solution developed at the University of Waterloo gradually delivers the correct amount of drug-infused nanoparticules to the surface of the eyeball over a period of five days before the body metabolizes them.

One weekly dose replaces 15 doses or more of the traditional treatments. The substance causes no irritation. If clinical trials are conclusive, this therapy could be available on the market within five years.
