Abstract
A punctum plug for insertion through a punctum opening of an eye and into the canaliculus to occlude the punctum opening and canaliculus is shown. The punctum plug, or implant, comprises an elongated member having a pair of spaced ends wherein one of the pair of ends includes a distal section, preferably in the form of collapsible expanded section which terminates in a distal tip which extends in a direction substantially normal or perpendicular to the central axis. The other end of the pair of ends includes a thin retaining lip which extends in an anterior direction and which is adapted to be oriented to extend beyond the edge of the punctum opening and to engage the lip margin defining the eyelid. The elongated member, including the collapsible expanded section and distal section, are formed of a dimension to pass through a punctum opening of an eye. A method for treating external eye condition due to a deficiency of tears utilizing the punctum plug is also shown.
