# What is 3-snip procedure for canaliculitis?

The 3-snip procedure is a minor operation on the punctum and canaliculus, often used in chronic canaliculitis or tear drainage problems. It enlarges the opening of the tear duct to improve cleaning and drainage.

## How the 3-snip procedure works

Under local anaesthetic, three small cuts reshape the punctum into a larger opening, making it easier to clear debris and allow tears to flow. Additional measures such as curettage or antibiotics may be used at the same time to treat infection.

- Typically performed in the procedure room with you awake
- Discomfort is usually mild and short-lived
- Lubricants and drops are often used for a short period afterwards
- Further lacrimal surgery may be considered if watering persists
