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. Fitting is a quick procedure in the clinic chair, usually without an anaesthetic injection. None of Eye Surgery Clinic's partner clinics publishes a punctal plug price, so what you pay depends on the clinic you choose.
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, iLux 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.
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 to ask a clinic
None of Eye Surgery Clinic's partner clinics publishes a price for punctal plugs. Sapphire Eye Care does not offer dry eye treatment, and dry eye treatment is not on Precision Vision London's treatment list, so we do not quote a figure: prices vary by clinic. What any clinic charges will depend on the choices below, so ask for the fee in writing before you book.
- Plug type: temporary collagen plugs as a trial, or semi-permanent silicone plugs for ongoing dry eye.
- How many puncta: one or both eyes, and whether the upper puncta are treated as well as the lower.
- The assessment: ask whether the dry eye assessment and tear film tests are charged separately from the fitting.
- Follow-up: ask whether the review visit is included in the fee.
- Insurance: check with your insurer what your policy covers and whether you need pre-authorisation.
Payment terms are set by each clinic, so ask for them in writing before you book.
