A drug-dispensing lens

contact lensTaking eyedrops multiple times a day is no picnic, and as much as 90 percent or more of the medicine ends up outside the eye, which pretty much defeats the purpose. Now, researchers led by Children’s biomaterials guru Dan Kohane, MD, PhD, report that they’ve developed a special contact lens, currently in animal testing, that gradually dispenses meds for up to 100 days. This could be a boon for patients with glaucoma, dry-eye and other eye diseases that require frequent drops.
