The microneedles are a more efficient and less traumatic tool for delivering therapeutic drugs to the back of the eye
Article Summary
Researchers at the Georgia Institute of Technology and Atlanta's Emory University have developed microneedles less than a millimeter in length that can deliver drug molecules and particles to the region in the back of eye. The new technology provides an alternative to current methods which are either invasive, with drugs being injected into the center of the eye, or based on eyedrops, which are limited in their effectiveness.
