A coiled PDO filament on a blunt cannula for the eye area
NEO Eye Cannula (Screw) is the coiled counterpart to our Eye Cannula (Mono). Same blunt U-type cannula, same 29G and 30G gauges, but the filament is wound in a spiral rather than lying straight.
The coil packs more polydioxanone into the same length of track. In periorbital skin — where you want the fewest possible passes through dense vasculature — getting more stimulus per insertion is a meaningful advantage. The spiral also distributes that material through the tissue column rather than along a single line.
Read the next section before you treat. This listing previously carried several claims about eyelid surgery and ptosis that we have removed. They were not minor overstatements, and a practitioner acting on them could cause real harm.
A coiled filament packs more material into the same insertion than a straight one — useful where passes should be minimised.
Displaces periorbital vessels rather than cutting them, which is the main downtime reduction available in this area.
Material spreads through the tissue column rather than along one plane.
No barbs. It stimulates collagen; it does not lift, and it does not treat eyelid conditions.
Why practitioners stock NEO Eye Cannula (Screw)
The coil delivers more material per insertion than a straight filament, which matters in an area where every additional pass adds bruising risk.
Periorbital vasculature is dense and superficial. A blunt tip is the single biggest reduction in visible downtime available here.
29G × 38 mm and 30G × 25.4 mm. Standard facial thread gauges are too heavy for periorbital skin.
Same format with a straight filament, for when the lightest possible touch is wanted instead.
Treatment areas
Periorbital applications for a coiled smooth PDO thread. All are skin-quality indications. Nothing here treats orbital fat, eyelid position or any eyelid condition.
Thin skin with poor elasticity at the lateral and lower orbit, where a coiled filament delivers more stimulus per pass than a straight one. The core indication for this product.
Increasing dermal thickness in thin lower-lid skin. Distinct from addressing a fat-pad bulge, which no thread affects.
Crinkled texture at the lateral canthus, often alongside botulinum toxin for the dynamic component. The two address different causes of what patients describe as one problem.
Patients prone to bruising, or those who cannot accommodate visible downtime, where getting more stimulus from fewer insertions is the deciding factor.
PDO threads are sterile implantable medical devices. Which applications are permitted, and what training is required, is determined by the regulatory framework where you practise. Korea Filler Experts supplies the product; nothing here is a recommendation to treat any medical condition, and a patient presenting with ptosis or an eyelid abnormality should be assessed medically rather than treated aesthetically.

Checking the pack
- The model code matches your order — S2938-C and S3025-C differ in both gauge and length.
- Each blister is intact and dry. A breached sterile barrier makes that unit waste.
- The expiry date is clear. PDO hydrolyses with moisture.
- The pack holds 10 pieces.
The coil is pre-formed. Do not attempt to straighten or re-wind it — the spiral is the product.
What each component does
Three things this product does not do
Earlier versions of this listing claimed otherwise. We have removed those claims and would rather explain why than quietly delete them.
- It is not a thread blepharoplasty. Blepharoplasty is surgical removal or repositioning of eyelid skin and fat under direct vision. A PDO thread placed subdermally does none of that. The phrase borrows a surgical term for a non-surgical product, and a patient hearing it will expect a surgical result.
- It does not treat herniated lower-lid fat. A true under-eye bulge is orbital fat pushing forward through the septum. Threads do not reach it, reduce it or restrain it.
- It does not treat eyelid ptosis. Ptosis is a problem of the levator muscle or its aponeurosis — or, less commonly, a sign of a neurological or neuromuscular condition that needs diagnosis. Offering a thread for a drooping lid is ineffective at best, and at worst delays the assessment of something that matters. New or progressive ptosis warrants medical referral, not an aesthetic appointment.
What it does do
It stimulates collagen in thin, lax, crepey periorbital skin, thickening the dermis along the treated tracks over four to eight weeks. In an area where the dermis is thinnest to begin with, that change is proportionally more visible than elsewhere — which is a real and worthwhile effect, described accurately.
Reading the specifications
- 29G and 30G — cannula diameter; higher number means thinner.
- Cannula vs thread length — the filament extends beyond the cannula so it stays in tissue as it withdraws.
- USP 6-0 and 7-0 — filament thickness on the standard suture scale, where more zeros means thinner.
How to use NEO Eye Cannula (Screw)
Reference information for practitioners already trained in periorbital work. A coiled filament occupies more space than a straight one, so the depth margin in this already-unforgiving area is smaller still.
Step by step
-
Confirm you are treating skin
Establish that the complaint is skin laxity and texture, not fat herniation and not ptosis. If it is either of those, this product is not the answer and a referral may be.
-
Plan entry and tracks with the patient upright
Mark entry points and tracks before they lie down, siting entries where a small mark will be inconspicuous.
-
Prepare and anaesthetise
Thorough antisepsis — this is an implant. Topical anaesthetic is usually adequate at these gauges, with a little local at the entry port if needed.
-
Create the entry port
Make the entry with a sharp needle of appropriate gauge. The blunt cannula cannot penetrate intact skin.
-
Advance in the subdermal plane
Advance along the marked track at consistent depth. Go slightly deeper than you would with the Mono version — a coiled filament has more bulk and shows more readily.
-
Withdraw and inspect
Withdraw the cannula while holding the thread, then inspect in good light at several angles before placing the next. Periorbital irregularity is far easier to prevent than to correct.
-
Trim flush
Trim protruding thread at skin level with the tissue in neutral position.
Administration notes
Place fewer than you would of the Mono version. Each coiled thread carries more material, so a Mono-density plan over-treats. Practitioners switching between the two commonly over-place on the first few cases.
If a patient presents with a drooping upper lid, stop. New, asymmetric or progressive ptosis can indicate a third nerve palsy, myasthenia gravis, or a Horner’s syndrome among other causes. An aesthetic appointment is the wrong setting to manage it, and offering a thread treatment for it delays the assessment that patient needs. Refer.
- Single use. Never re-sterilise or reuse a cannula or thread.
- Do not place over active infection, blepharitis, or recently placed tear-trough filler.
- Stay well clear of the orbital rim and the globe. Nothing goes inside the orbital septum.
- Dispose of entry needles into a sharps container per local clinical waste requirements.
After treatment
- Periorbital bruising and swelling are common and can persist seven to ten days — longer than elsewhere on the face. Say so beforehand.
- Sleep with the head elevated for the first several nights
- No eye rubbing, vigorous cleansing or facial massage for two weeks
- No saunas, steam rooms or strenuous exercise for 48 hours
- No eye make-up for 24 hours; defer contact lenses for the first day
- Any visual disturbance, severe pain or spreading redness needs same-day assessment
Storing and handling NEO Eye Cannula (Screw)
Store at room temperature in a dry place, away from direct sunlight. No refrigeration and no cold chain.
Each unit is individually sealed and sterile. Do not use any whose blister is open, torn, damp or damaged. Never re-sterilise — autoclaving destroys PDO.
The spiral is formed during manufacture. Do not straighten or re-wind it, and avoid dragging the thread against packaging — a disturbed coil no longer distributes material as designed.
Single use only. Do not reuse, re-sterilise or repackage. Dispose of used cannulas and entry needles into a sharps container, and unused product as clinical waste in line with local requirements.
What's included
Entry needles are required and not supplied — a blunt cannula cannot make its own entry port. Antiseptic, topical anaesthetic and sharps disposal are also not included.
NEO Eye Cannula (Screw) — frequently asked questions
What is this product?
A coiled polydioxanone filament delivered through a blunt U-type cannula at 29G or 30G, intended for periorbital skin. The coil packs more PDO into the same track than a straight filament does.
Is this a non-surgical blepharoplasty?
No. We removed that phrase from this listing because it is misleading in a way that matters.
Blepharoplasty is surgery: eyelid skin and fat are removed or repositioned under direct vision. A PDO thread placed subdermally does neither. Borrowing the term invites a patient to expect a surgical result from a collagen-stimulating treatment, and they will not get one.
Will it treat eyelid ptosis?
No, and this is important. Ptosis is a problem of the levator muscle or its aponeurosis, and new or progressive ptosis can also signal a neurological or neuromuscular condition that needs diagnosing.
Offering a thread for a drooping lid is ineffective, and it risks delaying assessment of a cause that matters. A patient presenting with ptosis should be referred, not treated.
Will it get rid of under-eye bags?
No. “Bags” usually means herniated orbital fat — the fat pads behind the orbital septum pushing forward. Threads do not reach it or affect it; that is a surgical problem.
What threads address is thin, crepey, lax skin, which is a different problem that can look similar at a glance.
How does this differ from the Mono version?
Same cannula, same gauges, same blunt delivery. The filament is coiled rather than straight, so it carries more PDO in the same track and distributes it through the tissue column rather than along a line.
Choose Screw when you want more stimulus from fewer passes; Mono when you want the lightest possible touch in very thin skin. Place fewer Screw threads than you would Mono.
Why a cannula rather than a needle?
Periorbital vasculature is dense and superficial, and skin this thin shows bruising for a fortnight. A blunt tip pushes vessels aside rather than cutting them, which substantially reduces that. The cost is needing a sharp needle to make the entry port.
How soon will the patient see a change?
The collagen response builds over roughly four to eight weeks. Anything visible in the first week is swelling, not result — and periorbital bruising lasts longer than elsewhere, seven to ten days being normal.
How long does the effect last?
The PDO hydrolyses over roughly six months; the collagen laid down around it persists beyond that. Review at six to nine months and plan from what you see rather than promising a figure.
Do they need refrigeration?
No. Room temperature, dry, out of direct sunlight — no cold chain to manage.
Who can buy and use these?
Threads are sterile implantable medical devices. Periorbital work requires specific training in that anatomy and in recognising which presentations should be referred rather than treated. We supply to practitioners qualified to perform the procedure in their jurisdiction, and do not sell to consumers.
