Abstract

A punctum plug includes a proximal head, a shaft, and a distal body, and an axial bore. The head is defined by a flexible circular flange with a convex upper portion and a concave lower portion. The body defines a frustoconically tapered distal tip and a two wings that extend in an arc and taper in thickness. The wings can extend further radially than the flange of the head. A recessed groove is defined around the shaft extending between the wings and a wall structure connecting the winged portions of the body. The above structure permits one plug or fewer plugs to accommodate a broad patient population.
