What is Lacrimal Duct Probing?
This procedure uses a thin probe to gently open a blocked tear duct (nasolacrimal duct) and restore drainage. It may include irrigation, dilation, or placement of a temporary silicone stent to keep the duct open. Performed with topical anesthesia in adults; brief general anesthesia is common in infants.
What to expect after Probing?
- Mild irritation and tearing for 24–48 hours
- Antibiotic/steroid drops for several days
- If a stent is placed, a small loop may be visible at the inner corner; it is removed in 6–12 weeks
