Many people develop nearsightedness or farsightedness during their lifetimes. "Nanodrops," a new eye drop developed by Israeli ophthalmologists, has successfully fixed corneas in pig eyes, and could potentially do the same for people. Developed by researchers from the Shaare Zedek Medical Center and Bar-Ilan University in Israel, the drops could someday improve both our nearsightedness and farsightedness. Patients would have to launch an app on their phones to measure their eyes? refraction and create a laser pattern. This pattern would then be ?stamped? onto the corneal surface of the eyes. Not ready for human trials yet, but it?s encouraging research. https://futurism.com/nanodrops-repair-corneas-replace-glasses
