Abstract
A punctum plug includes a proximal head, a distal body, and a shaft between the head and the body. The shaft of the plug is provided with one or more foldable portions, thereby permitting the length of the shaft to vary depending upon the degree to which the folds are folded or unfolded. In addition, the folds permit the wall of the shaft to easily bend, permitting the head and body of the plug to lie along different axes. As a result, the plug is shaped to accommodate both relatively long and short vertical puncta and the body of the plug may be angled relative to the head to accommodate a variety of anatomical structures.
