Canthoplasty (a “cat eye lift”) is a specialist eyelid procedure that reshapes the outer corner of the eye to create a lifted, almond contour. In London it typically costs £3,000–£6,000, takes 60–90 minutes as a day case, and has a 2–3 week initial recovery. Because it alters the structure of the eye itself, it is safest performed by a Consultant Oculoplastic (eye) Surgeon. At Eyes Defined in Marylebone, it is carried out by ophthalmic surgeon Dr. Ahmad Aziz.
Tired-looking, downturned, or hollow outer eyes can make you appear exhausted no matter how rested you are. If you have searched for a way to subtly lift and “open” your eyes — without the frozen, over-pulled look you have seen online — canthoplasty may be the answer. This guide gives you the honest clinical detail: what the procedure does, exactly what it costs in London in 2026, the real risks, and the results you can realistically expect. It is written from the perspective of Dr. Ahmad Aziz, a Consultant Ophthalmic and Oculoplastic Surgeon practising in the Harley Street medical district.
What Is Canthoplasty? The Cat Eye Lift Explained
Canthoplasty is a precise surgical procedure that reshapes the lateral canthus — the point where your upper and lower eyelids meet at the outer corner of the eye. By repositioning and tightening the supporting tendon, your surgeon can elevate a downward-tilting corner, creating a gently upswept, almond-shaped eye. It is this lifted angle that people describe as a “cat eye” or “fox eye” result.
Unlike a temporary trend, surgical canthoplasty produces a structural, long-lasting change. It is frequently combined with blepharoplasty (eyelid surgery) or a brow lift when the goal is broader eye rejuvenation, but it can also be performed on its own to refine eye shape.
Canthoplasty vs Canthopexy vs Thread Lift
These three are often confused. A canthopexy is a less invasive tightening of the existing tendon — ideal for mild laxity or as support after lower-lid surgery. A canthoplasty is more comprehensive, involving actual reconstruction and repositioning of the outer corner, and is used when more correction or reshaping is needed. A thread lift, by contrast, is non-surgical: dissolvable threads suspend the soft tissue for a temporary lift lasting roughly 6–18 months. Only surgical canthoplasty changes the underlying structure, which is why its results endure for years rather than months.
Are You a Candidate?
You may be a strong candidate if you have a negative canthal tilt (outer corners sitting lower than the inner corners), visible scleral show (white showing beneath the iris), lower-eyelid laxity, or a tired, hollow outer-eye appearance — whether from ageing or natural anatomy. Canthoplasty also has important functional uses: correcting ectropion (an outward-turning lower lid) or supporting the lid after trauma or previous surgery. A thorough consultation determines whether your concern is best addressed by canthoplasty, canthopexy, or a combination procedure.
Why an Oculoplastic Surgeon Matters (Not Just Any Cosmetic Clinic)
This is the single most important decision you will make. Canthoplasty is performed millimetres from your eye and alters the structure that holds your lower lid in place. Done well, it looks effortless. Done poorly, it can cause asymmetry, lid malposition, or a permanently “rounded” or pulled-down eye.
There is a clear hierarchy of expertise. A medical-spa practitioner offering a non-surgical “fox eye” cannot perform this surgery at all. A general cosmetic or plastic surgeon may operate on faces but does not specialise in the eye. An oculoplastic surgeon is an ophthalmologist — an eye doctor — with additional subspecialty training in eyelid and orbital surgery. They understand the eye as a functioning organ, not just a feature to be reshaped.
Dr. Ahmad Aziz is a Consultant Ophthalmic and Oculoplastic Surgeon who operates at King Edward VII’s Hospital in Marylebone, within London’s renowned Harley Street district. His entire surgical focus is the eye and eyelid — which is precisely the expertise this procedure demands.

How Much Does Canthoplasty Cost in London? (2026)
In London, canthoplasty typically costs between £3,000 and £6,000. The range reflects several genuine factors: your surgeon’s expertise and track record, the complexity of your case, whether the procedure is combined with blepharoplasty, the type of anaesthetic used, and the standard of the surgical facility. Procedures performed by highly experienced oculoplastic surgeons in accredited hospital settings naturally sit at the higher, safer end of that range.
What’s Included in Your Price
Transparency matters, because a quoted “price” can hide extras. A complete canthoplasty fee at a reputable London clinic should cover your surgeon’s fee, the facility and theatre costs, the anaesthetic, and your follow-up appointments. At consultation you should be told in writing exactly what is and isn’t included, so there are no surprises. If a quote seems unusually low, ask what has been left out.
Why “Cheaper Abroad” Often Costs More
Medical-tourism packages advertising canthoplasty at a fraction of UK prices are tempting, but the saving can be illusory. The advertised price rarely accounts for travel, accommodation, the difficulty of attending follow-up appointments, and — most importantly — what happens if there is a complication. Revision surgery on an eyelid operated on overseas is complex and expensive, and managing a complication thousands of miles from your surgeon is stressful and risky. Choosing a London surgeon means your aftercare, and any adjustments, are handled by the person who knows your anatomy.
Canthoplasty Risks & Safety: An Honest Breakdown
Every surgery carries risk, and any clinic that tells you otherwise is not being straight with you. Being fully informed is part of giving meaningful consent — and it is how realistic expectations are set.
Common, Temporary Side Effects
Most patients experience some swelling, bruising, mild tightness, and watering of the eye in the first days. These are normal parts of healing and typically settle within one to two weeks. You may also feel some temporary dryness or sensitivity, which is managed with lubricating drops.
Rare Complications & How We Minimise Them
Less common but more significant risks include asymmetry between the two sides, over- or under-correction of the lift, eyelid malposition such as ectropion, and visible scarring. The strongest safeguard against all of these is surgical experience and precise planning: the canthal position is marked while you are sitting upright, because the eye’s appearance changes when you lie down. An eye-specialist’s understanding of lid mechanics is what keeps these risks low and results natural.

The Canthoplasty Procedure: Step by Step
Before Surgery — Consultation, Marking & Anaesthetic
Your journey begins with a detailed consultation assessing your eyelid structure, canthal position, skin quality, and goals. Standalone canthoplasty is usually performed under local anaesthetic with light sedation; when combined with blepharoplasty or a brow lift, a general or TIVA anaesthetic may be used. Before surgery, your surgeon marks the planned corner position while you sit upright to ensure accuracy.
On the Day — The Day-Case Procedure
Canthoplasty is carried out as a day case, meaning you go home the same day. The procedure itself takes around 60 to 90 minutes for a standalone case. Through a small, well-hidden incision at the outer corner, the surgeon repositions and secures the canthal tendon, then closes with fine sutures placed to keep scarring discreet. You will rest briefly afterwards before being discharged with clear aftercare instructions.
Recovery Timeline & Long-Term Results
Week-by-Week Recovery
In the first 48 hours, expect swelling and bruising; cold compresses and keeping your head elevated help considerably. By the end of week one, most bruising begins to fade and any sutures are typically reviewed or removed. By weeks two to three, the majority of visible swelling has resolved and many people feel comfortable returning to normal social activities. Strenuous exercise, eye rubbing, and heavy sun exposure should be avoided during this early period.
When You’ll See Final Results & How Long They Last
While you will notice a difference quickly, the final, settled result emerges over 6 to 12 months as the tissues fully heal and scars mature to near-invisibility. Surgical canthoplasty offers long-lasting, structural results — typically many years — though the natural ageing process continues over time. Studies report high satisfaction rates of around 85–90% when the procedure is performed by a qualified specialist.
Realistic Results: Natural Enhancement vs the “Overdone” Look
The dramatic, sharply angled “fox eye” seen on social media is often the product of heavy photo editing or thread lifts pulled to an extreme — and attempting to recreate it surgically tends to look unnatural and ages poorly. A well-judged canthoplasty does something subtler and more powerful: it restores or refines your natural eye shape so you look refreshed and alert, not operated on. The aim is harmony with the rest of your face. An experienced oculoplastic surgeon will tell you honestly what your anatomy can and cannot achieve, steering you toward a result that still looks like you.

Frequently Asked Questions
Canthoplasty in London typically costs between £3,000 and £6,000. The exact price depends on your surgeon's expertise, the complexity of your case, the anaesthetic used, and whether it's combined with blepharoplasty. A reputable clinic includes surgeon, facility, anaesthetic, and follow-up fees in the quote.
Canthoplasty is considered safe when performed by a qualified specialist, with satisfaction rates of around 85–90%. Because it alters the structure around the eye, it is safest in the hands of an oculoplastic (eye) surgeon, who minimises risks such as asymmetry or eyelid malposition through precise planning.
Surgical canthoplasty produces long-lasting, structural results that typically endure for many years — far longer than non-surgical alternatives like thread lifts, which last only 6–18 months. The natural ageing process does continue over time, but the underlying reshaping is permanent.
Canthoplasty is performed under local anaesthetic with sedation (or general anaesthetic if combined with other surgery), so you feel no pain during the procedure. Afterwards, most patients report mild tightness or discomfort rather than significant pain, easily managed with simple pain relief.
Initial recovery takes about 2 to 3 weeks, when most swelling and bruising resolve and many people return to normal social activities. Final, fully settled results emerge over 6 to 12 months as the tissues heal and scars fade.
Incisions are placed discreetly at the outer corner of the eye, so scarring is usually minimal and well-hidden. Under expert care, scars typically fade to near-invisibility within several months of surgery.
A canthopexy tightens and supports the existing tendon and is less invasive, suited to mild laxity. A canthoplasty is more comprehensive, involving repositioning and reconstruction of the outer eyelid corner for greater reshaping. Your surgeon recommends the right option based on your anatomy.
Yes. Canthoplasty is frequently combined with blepharoplasty (eyelid surgery) or a brow lift for fuller eye rejuvenation. Combining procedures can deliver more comprehensive results in a single recovery period, and is planned individually during your consultation.
A negative canthal tilt is when the outer corners of the eyes sit lower than the inner corners, which can create a downturned, tired, or sad appearance. Canthoplasty can elevate the outer corner to correct this and restore a lifted, alert look.
Good candidates have a downturned (negative) canthal tilt, scleral show, lower-eyelid laxity, or a tired outer-eye appearance, and are in good general health with realistic expectations. A consultation confirms whether canthoplasty, canthopexy, or a combined procedure best suits you.
Because canthoplasty changes the eyelid's underlying structure, it is not simply reversible, and revision surgery is more complex than the original procedure. This is exactly why choosing an experienced eye-specialist surgeon from the outset is so important.
Choose a surgeon on the GMC Specialist Register with specific oculoplastic (eyelid) expertise, who operates at a CQC-regulated facility and shows genuine before-and-after results. An ophthalmic surgeon who specialises in the eye offers the highest level of safety for this procedure.
