SOFT PLUG® Flow Control, Preloaded, by OASIS®
The OASIS Medical Silicone Punctal Plug has a thin head portion designed to remain outside the punctum and rest on the eyelid. The central shaft portion of the plug has a smaller diameter than the head portion and is designed to fit through the punctal opening. The nose portion of the plug has a larger diameter which is designed to fit in the canaliculum in order to retain the plug in the punctum. Silicone punctal plugs are available in two styles: the original punctum plug with a closed nose portion which blocks flow through the punctal opening, and the Flow Control punctal plug with an opening through the nose portion which allows flow through the punctal opening.
