Med Gag The team of MIT, Massachusetts Eye and Ear Infirmary and Children’s Hospital have developed a hydrogel lens with a polymer film inside that contains medication. The medication is released from the contact lens gradually and can be controlled by altering the properties of the Polymer file and lens. 

Several other research groups have explored contact lenses that carry medications, but they have struggled to achieve extended release of the drugs. The Eyenovations team found a way to make their lens deliver high doses of medication for up to 100 days–a process they are now patenting. They plan to develop commercial lenses, using materials approved by the Food and Drug Administration (FDA), that deliver drugs for up to 30 days–the FDA’s limit for single-use contact lenses.
