No More Eye Drops? Contact Lens Protoype Delivers Glaucoma Meds

Like a miniature donut stuffed inside a tiny pita pocket, a common glaucoma medicine is sandwiched inside this specially designed contact lens. In laboratory experiments, the lens, which can also correct vision, releases the eyesight-saving medication at a steady rate for up to a month. Its construction offers numerous potential clinical advantages over the standard glaucoma treatment and may have additional applications, such as delivering anti-inflammatory drugs or antibiotics to the eye.
What makes the new lens different from other prototypes before it, added Kohane, is the many-layered construction that places a ring of drug-releasing film in standard, FDA-approved contact lens materials. Other designs have most often used a pre-made lens dipped in a drug solution, which then leached out into the eye rapidly and inconsistently.
