Israeli researchers have developed revolutionary eye drops, or “nanodrops,” which they claim can replace eyeglasses. The tests on pigs' corneas and human clinical trials conducted at Bar-Ilan University and the Shaare Zedek Medical Centre in Jerusalem have given encouraging results, according to reports in Australia's Insight magazine. The drops used in the tests are designed to combat myopia and hyperopia, but the process has the potential to treat other refractory conditions as well, scientists said. Unlike traditional laser surgery, the new treatment affects only the upper part of the cornea.
