Punctual plugs are characterized by their small, round shape and are typically used to occlude the tear ducts, aiding in the management of dry eye conditions. Made from materials like silicone or collagen, they are designed to block the drainage of tears, thus increasing tear retention on the eye's surface. These plugs can be temporary or permanent and are often inserted in a clinical setting to provide relief from symptoms associated with insufficient tear production.
