FCI Nunchaku® is a pushed silicone self-retaining bicanalicular nasolacrimal intubation stent that acts like a conformer, allowing tears to be drained by capillarity. The metallic guides are located inside the lumen, not as an extension of the stent as in conventional intubation sets. Therefore, no nasal retrieval is needed.
