A lacrimal tube is a small, implantable device designed to create or maintain a drainage pathway for tears from the eye into the nasal cavity or sinus. It helps treat conditions like blocked tear ducts (epiphora) or chronic sinus issues by ensuring proper fluid flow, often used after surgery to open or widen the drainage passage.
These devices are typically implanted during procedures like dacryocystorhinostomy (DCR) and are made from materials like silicone or glass. Regulation varies by jurisdiction, but they are generally classified based on their surgical implantation and intended use, with oversight ensuring safety and efficacy for tear drainage or sinus irrigation.
