Children's Hospital Boston -- Boston, Mass. -- Taking eye drops multiple times a day can be difficult for patients to do, and because of blinking and tearing, as little as 1 to 7 percent of the dose is actually absorbed by the eye. Now, researchers led by Daniel Kohane, MD, PhD, director of the Laboratory for Biomaterials and Drug Delivery at Children's Hospital Boston, have developed special contact lenses that can gradually dispense a constant amount of medication to the eye, at adjustable rates. They describe their prototype lens in the July issue of Investigative Ophthalmology and Visual Science.
