OASIS SOFT PLUG Flow Control Punctal Plugs - Box of 2 0.7mm

Made of silicone and preloaded, the SOFT PLUG Flow Control Punctal Plug is another version/style of the OASIS SOFT PLUG Silicone Plug. While the original silicone plug blocks flow through the punctal opening, Flow Control plugs have an opening through the nose portion which allows flow through the punctal opening. In other words, the Flow Control plug monitors flow to ensure the appropriate number of tears remain on the eye's surface
