Nanodiamond-embedded contact lenses may improve glaucoma treatment

Glaucoma is a pervasive disorder that occurs when there is a buildup of pressure in the eye. If left untreated, this can damage the optic nerve, resulting in vision loss. Bioengineers have developed a nanodiamond-embedded contact lens that may improve glaucoma treatment by localizing and sustaining drug release that can be triggered using tears. The researchers showed that the nanodiamonds even improved lens durability while maintaining wear comfort.
