🧵 Surgical Workflow Summary

StepDetails

① Locate proximal cut end	Use light probe or dye; general anesthesia preferred
② Insert silicone tube	Choose Monoka (single) or Bika (double) type
③ Suture canalicular wall	Around the inserted stent
④ Address medial canthal tendon	If also injured, repair accordingly

✅ Surgical Tips

• Delay repair 24–48 hours post-trauma (unless animal bite)
• Upper canaliculus only? Still worth repairing
• Choose stent type based on case: Monoka = easier, Bika = more stable
