Abstract: Devices and methods for inserting a pre-loaded intracanalicular plug for the treatment of dry eyes. In one embodiment, an intracanalicular plug inserter device includes: (a) an elongate body having a longitudinal axis, the body having: an inserter end, wherein the inserter end has an opening therein; and a distal end, wherein the distal end is longitudinally opposing the inserter end; and (b) a plug ejector, wherein the plug injector comprises: a slider; and a rod coupled to a first end of the slider, wherein the plug ejector is configured to be moveable between a first position adjacent an opening in the inserter end and a second position that is further from the opening. The plug is mounted within the body and abuts first end of the rod adjacent the opening in the inserter end.

Abstract: Methods and apparatus for treatment of dry eyes by providing a single apparatus for measuring the diameter of the lacrimal punctum and, based on the measured punctal diameter, inserting therein an appropriately sized punctum plug.

Abstract: A punctum plug includes a distal tip, a proximal cap and a body connecting the tip to the cap. The cap has a proximal surface which remains exposed in the eye upon implantation of the punctum plug. A passage for an insertion tool extends distally in the punctum plug from an opening along the proximal surface. One or more recesses in the proximal surface collect tear fluid by surface tension, and each recess is laterally offset in its entirety from the opening and does not overlap or align with the opening. The number of recesses is indicative of the size of the punctum plug. A method of punctal occlusion involves collecting tear fluid in the one or more recesses and adhering the tear fluid in the one or more recesses by surface tension.
