Punctal plugs are small, biocompatible implants placed into the eye's tear-drainage openings (the puncta) to slow how quickly tears drain away, keeping more of your own natural tears on the eye. They are a mainstay treatment for moderate aqueous-deficient dry eye when artificial tears alone are not enough. At our South England partner clinics, fitting takes around five minutes per eye with no anaesthetic. Self-pay pricing starts from £300 for both eyes with temporary collagen (dissolvable) plugs, and from £500–£650 for both eyes with semi-permanent silicone plugs, including the fitting.
What are punctal plugs?
Each eye has two tiny drainage holes — the puncta — located on the inner edge of the upper and lower eyelids near the nose. Tears that wash across the eye normally drain through these openings into the nose. In dry eye disease, your eyes either don't make enough tears or the tears evaporate too fast, leaving the ocular surface inflamed, gritty and sore.
A punctal plug is a soft device, roughly the size of a grain of rice, inserted into the lower (and sometimes upper) punctum. By partly blocking the drainage channel, the plug keeps your natural tears — and any artificial tears you instil — on the eye for longer. This is called punctal occlusion. It is one of the most established procedures in dry eye care: simple, quick, drug-free and reversible.
Who benefits from punctal occlusion?
- Aqueous-deficient dry eye — not enough tear volume, often confirmed by a low Schirmer test
- Dry eye not controlled by drops alone — despite regular preservative-free artificial tears
- Contact lens wearers with dryness and discomfort
- Screen-heavy lifestyles and reduced blink rate causing surface dryness
- Sjogren's syndrome and other autoimmune conditions with severe tear deficiency
- Post-laser or post-cataract dryness while the ocular surface recovers
Punctal plugs work best when the problem is too few tears. If your dry eye is mainly driven by meibomian gland dysfunction (MGD) — where the oily layer of the tear film is the issue — your consultant may first recommend a gland-focused treatment such as LipiFlow thermal pulsation, TearCare or IPL therapy. Many patients benefit from a combined approach.
Not sure which dry eye treatment is right for you? A consultant dry-eye assessment includes tear film tests to pinpoint the cause before any treatment.
Book a dry eye assessmentPunctal plug options
There are two broad families of punctal plug. Your consultant will recommend the right one based on the severity and likely duration of your dry eye, and many patients start with a temporary plug as a “trial” before committing to a longer-lasting one.
Most patients start with the lower puncta of both eyes. If symptoms are only partly improved, the upper puncta can be plugged at a later visit. Where dry eye is severe — for example in advanced Sjogren's or graft-versus-host disease — your consultant may combine occlusion with an amniotic membrane graft or specialist drops such as Miebo (perfluorohexyloctane) or Tyrvaya nasal spray.
What happens during the fitting
Having punctal plugs fitted is one of the quickest procedures in ophthalmology. It is done in the clinic chair at the slit lamp, takes about five minutes for both eyes, and needs no anaesthetic injection — most patients feel nothing more than a light touch.
- Your consultant confirms the diagnosis with tear film tests (such as a Schirmer test and tear break-up time) and examines the puncta.
- The eyelid is gently steadied and the punctum is identified at the slit-lamp microscope. Anaesthetic drops may be used for comfort, but are often unnecessary.
- The correctly sized plug is placed into the punctum using a fine applicator. Silicone plugs sit with a small cap at the lid margin; collagen plugs dissolve in place.
- The process is repeated for the second eye. There is no cutting and no stitches.
- You can drive yourself home and return to work immediately — there is no downtime.
Aftercare & what to expect
There is essentially no recovery period. Many patients notice their eyes feel more comfortable within a day or two as natural tears are retained for longer. Here is what to expect:
Day of fitting
No downtime. Resume normal activities, screen work and driving straight away. Continue any prescribed drops.
First few days
Eyes typically feel less gritty and more comfortable. A brief awareness of the plug is normal and settles quickly.
Weeks 2–6
Follow-up review to check the plugs are well positioned and assess symptom improvement. Upper puncta can be added if needed.
Collagen plugs
Dissolve naturally over days to months. If they helped, a semi-permanent silicone plug can be fitted.
Silicone plugs
Stay in place long term and can be easily removed at any time if your dry eye improves or you no longer need them.
Side effects are uncommon. A small number of patients notice mild watering (epiphora) if tears are retained too well, occasional irritation, or — rarely — a plug that falls out or needs repositioning. These are easily managed at a follow-up visit.
Cost & what is included
Our punctal plug pricing is transparent and includes the fitting. Final cost depends on whether you choose temporary collagen or semi-permanent silicone plugs, and whether one or both eyes (and upper as well as lower puncta) are treated.
- Dry eye assessment / consultation: from £200, including tear film testing to confirm the cause of your dry eye.
- Temporary collagen plugs: from £300 for both eyes, including fitting — ideal as a trial.
- Semi-permanent silicone plugs: from £500–£650 for both eyes, including fitting and a follow-up review.
- Insurance: punctal occlusion is recognised by major UK insurers including Bupa, AXA, Aviva, Vitality and WPA — we can help with authorisation.
Prices reflect our Sapphire partner-clinic pricing across South England. The assessment fee is often credited toward treatment where plugs are fitted at the same visit — your coordinator will confirm at booking.
