Bilateral Sac Washout

What is a Bilateral Sac Washout?

A sac washout is a procedure used to flush out the tear drainage system and assess for blockages. It is commonly performed on both eyes (bilateral) when patients experience excessive tearing (epiphora) or recurrent infections.

What causes Tear Duct Blockages?

• Age-related narrowing of the tear drainage system
• Previous eye infections or inflammation
• Nasal conditions affecting tear drainage

How is a Blocked Tear Duct Treated?

A bilateral sac washout helps to clear minor blockages and confirm whether further treatment, such as surgery, is needed.

What does the procedure involve?

Under local anaesthetic, a fine tube is inserted into the tear duct, and sterile saline is gently flushed through to clear any obstruction.

Are there any risks or side effects?

• Mild stinging or watering of the eyes
• Temporary redness or irritation
• If the duct remains blocked, further treatment may be needed

What are the benefits?

• Relief from excessive tearing or discharge – not guaranteed.
• Helps diagnose underlying tear duct problems

Will I need a follow-up appointment?

Your doctor will advise if further treatment is necessary based on the results of the washout.
