Punctal plugs are tiny devices inserted into the tear ducts to conserve tears and relieve dry eye symptoms. Learn how punctal plugs work, who they suit, and what to expect from this quick, painless treatment.
Punctal plugs are small, biocompatible devices placed into the tear drainage ducts (puncta) to help the eyes retain more natural tears.
They are used to treat aqueous-deficient dry eye, where the eyes do not produce enough tears — often due to ageing, autoimmune conditions such as Sjögren’s Syndrome, or chronic dryness following surgery.
By blocking some (or all) of the drainage pathway, more tears remain on the surface of the eye.
This improves lubrication, reduces irritation, and creates a more stable tear film.
Punctal plugs may be temporary (dissolvable) or long-term (silicone), depending on the cause and severity of dry eye.
Assessment and tear evaluation:
The clinician measures tear production and checks for inflammation or gland dysfunction.
Selection of plug type and size:
The plug is chosen to match the punctum precisely for comfort and stability.
Insertion of the plug:
Anaesthetic drops are applied
The plug is gently placed into the lower (or upper) punctum using a micro-applicator
No cutting, stitches, or injections are involved
Tear retention improves immediately:
Tears remain on the eye for longer, creating better lubrication and comfort.
Temporary plugs dissolve over weeks; silicone plugs remain until removed or replaced.
Increases tear retention and improves overall lubrication
Reduces burning, stinging, and gritty sensations
Helps watery eyes caused by reflex tearing
Useful for autoimmune-related dry eye (Sjögren’s, rheumatoid arthritis)
Quick, painless, and non-invasive
Can be used alongside BlephEx, IPL, or warm compress therapy
Suitable when lubricating drops are not enough
Lower risk than systemic medication for dry eye
Punctal plugs may be recommended if you have:
Aqueous-deficient dry eye
Dry eye related to Sjögren’s Syndrome
Post-surgical dryness, especially after LASIK, LASEK, or cataract surgery
Symptoms that do not improve with lubricants alone
Chronic inflammation causing poor tear volume
Difficulty sustaining comfort with contact lenses
Reflex watering caused by underlying dryness
They are generally suitable for most patients once inflammation is controlled.
Anaesthetic drops numb the area
You may feel light pressure but no pain
The procedure takes 1–2 minutes per eye
No downtime — you can return to normal activities immediately
Some patients feel the plug initially but quickly adapt
Improvement in comfort can be noticeable within hours to days
Follow-up checks confirm correct plug positioning and tear-film stability.
Early use of punctal plugs can be especially helpful if:
Your dryness is causing damage to the ocular surface
You have autoimmune-related dry eye with poor tear quantity
You struggle with daily lubrication or need drops frequently
You have postoperative dry eye that is slowing visual recovery
Tear conservation protects the cornea and prevents chronic irritation.
No recovery time needed
Mild awareness of the plug for 24–48 hours is normal
Avoid rubbing the eyes
Use any prescribed drops as directed
Return for follow-up to ensure continued comfort and correct placement
Most plugs remain securely in place; however, some may dislodge and can easily be replaced.
