An Experimental Contact Lens to Prevent Glaucoma-Induced Blindness

on

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.
