Punctal Plugs

Punctal plugs block tear drainage, allowing your limited tear supply to stay on your eye longer. They’re a proven, reversible treatment for aqueous-deficient dry eye when drops and other therapies aren’t enough. Quick to place, no downtime, and easily removed if you change your mind.

The problem

Aqueous-Deficient Dry Eye

Your tear film has three layers: water (aqueous), oil (lipid), and mucus (mucin). In aqueous-deficient dry eye, your tear glands produce insufficient water—so even with frequent drops, your eyes stay dry.

This happens in Sjögren’s syndrome, age-related tear decline, hormonal changes, medication side effects, cancer treatment, and graft-versus-host disease. The conventional approach—artificial tears and anti-inflammatory drops—is temporary relief. Punctal plugs take a different approach: conserve whatever tears you produce so they stay on your eye longer and do more work.

Why tears drain away

Your tears drain through tiny openings called puncta near the inner corner of each eyelid. These lead to ducts that carry tears into your nasal passages. In aqueous-deficient dry eye, the limited tears you produce drain off your eye quickly—wasting the supply you have. Plugging these drainage points lets tears accumulate and lubricate your eye for longer between applications.

Mechanism

How Tear Drainage Works

Tears begin at the lacrimal gland above your eye, spread across the ocular surface with each blink, and drain through two microscopic openings—the upper and lower puncta—located at the inner corner of your eyelid. From there, tears travel through thin ducts called canaliculi, down into the lacrimal sac, and into your nasal passages. This is why your nose runs when you cry.

In aqueous-deficient dry eye, this drainage system works fine—but the tears available to drain are too few. By blocking one or both puncta with a small plug, we slow or stop drainage, letting your tears accumulate on your eye surface and stay there longer. The result is better lubrication, more comfort, and less dependence on frequent eye drops.

Two options

Temporary vs. Permanent Plugs

We offer both temporary and permanent plugs. Temporary plugs let you trial the effect before committing; permanent plugs provide lasting relief and can be removed anytime if your needs change.

Temporary (Collagen)

MaterialDissolvable collagen derived from absorbable tissue
Duration5–7 days, then self-dissolves
RemovalAutomatic; no action needed
Best forTrial therapy; assessing whether plugs will help
CostLower than permanent options
AdvantagesRisk-free test; reveals response within days

Permanent (Silicone)

MaterialMedical-grade silicone; inert and stable
DurationMonths to years; remains until manually removed
RemovalCan be removed anytime during office visit if needed
Best forLong-term tear conservation in confirmed aqueous-deficient cases
CostHigher initial cost; more durable
AdvantagesConsistent, lasting relief; fully reversible

Most patients start with temporary collagen plugs to confirm that occlusion helps. If you respond well, we upgrade to permanent silicone plugs for sustained relief.

Who benefits

Ideal Candidates

Punctal plugs are designed for aqueous-deficient dry eye—low tear production confirmed by clinical testing. They work best in patients who haven’t found sufficient relief from drops and anti-inflammatory therapy alone.

Aqueous-deficient dry eye

Confirmed low tear production on osmolarity, tear break-up time, and Schirmer testing. Plugs conserve whatever tears you produce.

Tear production

Sjögren’s syndrome

Autoimmune destruction of lacrimal tissue is a classic indication for punctal occlusion. Plugs can dramatically improve comfort for Sjögren’s patients.

Autoimmune

Post-menopausal dry eye

Hormonal changes reduce tear production in many women. Plugs are a non-hormonal, non-medication option for lasting relief.

Hormonal

Medication-induced dry eye

Some medications (antihistamines, decongestants, blood pressure drugs) reduce tear production. Plugs help while you’re on the medication.

Medication-related

Failed conventional therapy

Tried multiple artificial tear brands without sufficient relief. Plugs conserve your natural tears, delivering better results than synthetic replacements.

Refractory dry eye

Desire to reduce drops

Some patients simply want to reduce their drop frequency or escape drop-dependency. Plugs can cut drop use by 50% or more.

Drop reduction

Punctal plugs are not ideal for evaporative dry eye caused by meibomian gland dysfunction—those cases need lid therapy like UltraView DEL™ or LipiFlow instead. We assess your tear type and cause during your evaluation to ensure plugs are the right tool for you.

What to expect

The Insertion Procedure

Plug insertion takes 10 to 15 minutes and requires no numbing injection—just topical drops. There’s no downtime, no sutures, and no surgery. You’ll feel minimal discomfort and be done for the day.

Apply numbing drops

Topical anesthetic drops numb the eye so you won’t feel the insertion. The drops work within seconds and are completely safe.

Locate the punctum

Using magnification and a bright light, your optometrist identifies the tear drainage opening at the inner corner of your eyelid. It’s tiny—about the size of a pinhead.

Insert the plug

A specialised applicator gently places the plug into the drainage opening. You’ll feel slight pressure but no pain thanks to the numbing drops. The insertion itself takes seconds.

Verify positioning

Once inserted, we confirm the plug is properly seated and won’t be easily dislodged. For bilateral treatment, we can plug both upper and lower puncta, though we usually start with the upper to assess your response.

You’re done

No restrictions, no dressing, no sutures. You leave with your eye working to conserve tears immediately. Some patients feel a slight foreign-body sensation for hours to a day; this almost always resolves.

Timeline

Results and When to Expect Them

Punctal plugs work immediately by conserving tears. Most patients notice meaningful improvement within days to a week.

Immediately after insertion: You may feel a slight foreign-body sensation; this usually resolves within hours to a day
Hours 1–24: Some mild tearing or discharge is normal as tears accumulate on your eye
Days 2–3: Foreign-body sensation typically resolves completely
Days 3–7: Significant comfort improvement as your eye stays lubricated longer between applications
Week 2 and beyond: Full benefit realised; tear volume is measurably higher, staining decreases, and drop frequency often cuts by 50% or more

Reported outcomes: 60–80% of aqueous-deficient dry eye patients experience significant symptom improvement, measurable tear volume increase, and reduced drop dependency. Some patients respond even more dramatically. Plug effectiveness is confirmed by repeat tear testing at follow-up visits.

Connected care

Punctal Plugs Within the UVG Network

Dry eye is rarely isolated. When punctal plugs are part of your care plan, we coordinate with other specialties across the UVG network to address the full picture.

Meibomian gland disease? Many aqueous-deficient patients also have lipid-layer dysfunction. We layer punctal plugs with UltraView DEL™, LipiFlow, or manual gland expression to stabilise both aqueous and lipid components.

Severe post-surgical dry eye? After cataract surgery, refractive surgery, or corneal procedures, temporary plugs can bridge the recovery period while your eye heals. Our Uptown Eye Specialists colleagues refer post-operative patients to UDEI for plug assessment and coordinate long-term management.

Contact lens intolerance due to dry eye? If plugs restore tear stability, some patients can return to lens wear. Our team at U Optical can explore specialty contact lens options like sclerals if traditional lenses remain uncomfortable.

Home care and supplementation? Preservative-free artificial tears, omega-3 supplementation, and lid-hygiene products that pair well with punctal occlusion are curated by our clinicians and available through U Shoppe.

Common questions

Frequently Asked Questions

Absolutely. Temporary collagen plugs dissolve in 5 to 7 days, giving you a risk-free trial to see whether occlusion helps your symptoms. If you experience meaningful improvement and want sustained relief, we can upgrade to permanent silicone plugs. If you don’t respond or prefer not to continue, there are no lasting effects—the temporary plugs simply dissolve.

Initially, yes—some patients feel a slight foreign-body sensation for a few hours after insertion. This is because the plug is there and your eye is noticing it. However, this sensation almost always resolves within 24 hours as your eye adapts. Most patients find that the comfort benefit from conserved tears far outweighs any initial adjustment period. If persistent discomfort develops, we can remove the plug immediately.

Temporary collagen plugs dissolve automatically in 5 to 7 days—no removal needed. Permanent silicone plugs must be removed by an eye care professional during an office visit, which takes just a few minutes. We don’t recommend attempting self-removal of permanent plugs, as improper removal can irritate the punctal opening. If you decide plugs aren’t working for you, call us and we’ll remove them quickly and painlessly.

Silicone plugs are securely positioned and rarely shift or fall out, particularly if you avoid rubbing your eye in the first week. If a plug does become displaced (rare), we can easily reposition it at a routine visit. We check plug positioning and integrity at every follow-up exam, so any dislodgement is caught early and addressed quickly. Temporary collagen plugs are even more secure because they swell slightly as they hydrate, anchoring themselves in the punctal opening.

Most patients who need punctal plugs have an ocular surface that isn’t well-suited to ongoing contact lens wear—which is often why they ended up in our office. We typically ask patients to pause lens wear during the initial healing and response phase, then reassess candidacy as tear stability improves. For patients who still want contact lenses long-term, our colleagues at U Optical can discuss specialty lens options, including scleral lenses, which are often the right fit for a severe dry eye patient who struggles with soft lenses.
