A plug that securely fits in the punctal cavity eliminating the need for an anchor system or cap at the end of the plug. It consists of hydrogel material that absorbs tears and expands into a pliable, soft, and viscous substance. It takes about ten minutes for the plug to increase 20 times in volume, enabling it to conform to and fill the vertical canaliculus.
