Cantoplasty is a focused oculoplastic surgery that rebuilds or reshapes the outer corner of the eye to tighten a loose lower eyelid. In plain terms, it helps support eyelid position and can create a more almond-shaped contour for a refreshed look.
This short guide previews what the procedure changes, who may benefit, how it differs from related techniques, and what to expect before, during, and after surgery. It covers preparation, the typical outpatient steps, recovery timelines, likely results, and potential risks.
For many patients, the goals are either functional—improving eyelid closure and protecting the eye surface—or cosmetic, adjusting the outer corner and overall eye contour. Best outcomes depend on each person’s anatomy, realistic goals, and the surgeon’s experience with eyelid anatomy.
Timelines and final results vary by patient and by whether the procedure is combined with other eyelid or facial work. For more detailed clinical information and patient resources, see this page on canthoplasty details and care.
Key Takeaways
- Defines a targeted eyelid procedure that reshapes the lateral canthus for support or cosmetic change.
- Used for functional issues like eyelid laxity and for cosmetic enhancement of eye shape.
- Outpatient surgery with variable recovery; many resume daily activities in 1–2 weeks.
- Results depend on anatomy, clear goals, and the surgeon’s oculoplastic expertise.
- Risks include infection, dry eye, asymmetry, and changes in eyelid position.
What a Canthoplasty Procedure Does for Eye Shape and Lower Eyelid Support
Reshaping the lateral canthus changes how the eyelids meet at the outer corner and improves lower eyelid tension. The lateral canthus is the junction where upper and lower eyelids meet and it plays a key role in eyelid contour and support.
Reconstructing the lateral canthus
Canthoplasty reconstructs the corner of the eye to tighten a saggy lower eyelid. This reduces excessive white under the iris (scleral show) and helps the eyelid close more fully, protecting the cornea from exposure-related irritation.
Functional versus cosmetic goals
Functionally, the procedure aims to improve eyelid closure, comfort, and eye surface protection. Cosmetically, it can lift the outer corner to create a more almond or lifted eye shape.
Common concerns and realistic expectations
Surgeons address sagging, lower eyelid malposition, and visible sclera that cause a tired or pulled-down look. Patients should understand the operation targets the lateral corner and support; final results depend on baseline anatomy and whether additional eyelid work is done.
- Key effects: tighter lower eyelid, improved contour, reduced exposure symptoms.
- Research tip: match anatomy and goals rather than copying a specific eye shape when reviewing results photos.
Cantoplasty Candidates: Who May Benefit Most
Many patients seek correction when the outer lower eyelid droops, causes irritation, or alters eye contour. Surgeons evaluate whether the issue is mainly functional, cosmetic, or both.
Lower eyelid laxity and age-related drooping
Age-related eyelid laxity commonly causes sagging of the lower eyelid and visible white under the iris. When eyelid tone is weak, tightening improves closure and comfort.
Medical indications
Common medical reasons include ectropion (lid turns outward), entropion (lid turns inward), and exposure-related irritation from inadequate eyelid closure. Paralytic lagophthalmos may also prompt repair.
Revision after prior blepharoplasty
Patients with lower blepharoplasty complications—retraction, rounded corners, or unnatural contour—often need a reconstructive approach to restore support and natural shape.
“A careful exam of eyelid tone, canthal position, and eye surface health guides a tailored plan.”
- Evaluation includes eyelid laxity, symmetry, and dry-eye risk.
- Goals that require major reshaping may need extra caution.
| Candidate Feature | Typical Concern | Benefit from Procedure |
|---|---|---|
| Age-related laxity | Sagging, scleral show | Improved support and contour |
| Ectropion / Entropion | Irritation, lash rubbing | Restored lid position |
| Post-blepharoplasty changes | Corner rounding, retraction | Reconstructive correction |
Canthoplasty vs Canthopexy vs Blepharoplasty: Key Differences to Know
Choosing among eyelid procedures starts by matching the problem to the correct technique. Each approach affects the outer corner and eyelid support differently. Knowing limits and benefits helps set realistic expectations.
Cutting and repositioning versus reinforcement with sutures
Canthoplasty reconstructs the lateral canthus by releasing and repositioning tissue. It changes corner position and can alter horizontal eyelid length.
Canthopexy uses sutures to tighten and support the canthal tendon without cutting. It stabilizes the corner but generally does not change eyelid length or move the canthus.

Why blepharoplasty is commonly combined with canthal support
Blepharoplasty targets excess skin, fat, and contour of the lower eyelid. When skin or fat is removed, the lower lid can tighten and risk pulling.
Surgeons often add canthopexy or canthoplasty to reduce malposition risk and maintain a natural eye shape.
What each procedure can and cannot change
- Eyelid length: canthoplasty can alter horizontal length; canthopexy cannot.
- Corner position: canthoplasty repositions the outer corner; canthopexy only supports it.
- Contour and volume: blepharoplasty removes or recontours tissue but does not reconstruct the canthus.
“Reinforcement suits mild laxity; reconstruction fits significant droop, retraction, or prior surgical changes.”
| Procedure | Main Action | What it changes | When it is chosen |
|---|---|---|---|
| Canthoplasty | Resection and repositioning | Canthal position, outer corner shape, horizontal length | Significant droop, retraction, reconstructive needs |
| Canthopexy | Suture reinforcement | Stability and support without length change | Mild to moderate laxity, often with blepharoplasty |
| Blepharoplasty | Skin/fat excision and contouring | Eyelid contour and excess tissue, not canthal repositioning | Excess skin, puffiness, cosmetic contouring |
| Combined approach | Support + contour | Improved support and refined eyelid shape | When contouring risks lid malposition or when both support and tissue removal are needed |
How to Prepare for Canthoplasty Surgery and Consultation
A thorough preoperative plan helps patients and the surgical team align goals and expectations. The consultation is the key moment to review anatomy, discuss outcomes, and set a realistic timeline for recovery.
What to cover during the consultation
In a typical U.S. consultation the surgeon will perform an eye exam, assess symmetry, and review medical history. They will discuss expected results and any limits based on eyelid anatomy.
Essential questions to ask
- How will you support the lower eyelid and manage asymmetry?
- What is your revision policy and follow-up schedule?
- How long will the procedure take and what anesthesia is planned?
Pre-op instructions and hygiene
Common guidance includes lab tests when indicated, stopping blood-thinning meds or supplements, and quitting smoking to aid healing. Patients should switch to glasses instead of contacts for several days to weeks before the operation.
Avoid resurfacing facials or active topical products near the skin around eyes. Cleanse the eye area gently the night before surgery to lower infection risk.
Logistics and immediate postoperative care
Arrange a ride home and at-home help for the first 24–48 hours. The plastic surgeon or surgeon’s office will give written pre-op instructions and an estimated time for the canthoplasty surgery based on any combined procedures.
| Prep Item | Why it matters | When |
|---|---|---|
| Medication review | Reduce bleeding risk | 2+ weeks before |
| Contact lens pause | Protect cornea | Days–weeks before |
| Transport/home help | Safety and rest | Day of surgery |
What Happens During the Surgery: Steps, Incisions, and Anesthesia
On the day of surgery, the team follows a clear sequence so the surgeon can work precisely and safely. Patients check in, confirm markings, and discuss the chosen anesthesia option before the sterile prep begins.
Anesthesia choices and patient experience
Options include local anesthesia alone, local with IV sedation, or general anesthesia. With local, the patient is awake but numb; IV sedation provides relaxation; general makes the patient fully asleep. The anesthesia choice depends on the complexity and patient preference.
How the eyelid tendon and muscle are tightened
The surgeon tightens and repositions the eyelid tendon and adjacent muscle to reduce drooping. This restores lower eyelid support and refines the outer corner contour for improved function and shape.
Incisions, closure, and scarring
A small incision is placed near the eyelid, often hidden within natural creases. The site is closed with fine stitches designed for discreet scarring and precise healing.
Procedure time and immediate effects
Typical time ranges from about 30 minutes to 3 hours (commonly 1–3 hours) depending on laxity, revision work, or combined procedures like blepharoplasty. Patients should expect immediate swelling and bruising that peak in the first few days.

Recovery and Aftercare: Managing Swelling, Bruising, and Activity Limits
The first days after surgery are the most noticeable: swelling peaks and bruising often appears. Patients should expect soreness and visible changes during the initial 7–10 days, with steady improvement over the following weeks and months.
Immediate expectations
Soreness and swelling are normal. Cold compresses applied in 15-minute intervals help reduce swelling. Mild bruising typically fades within 7–10 days.
Protecting the surgical site
Do not rub the eye or eyelids. Keep the head elevated while sleeping and avoid direct pressure on the incision. Clean only as instructed by the surgeon.
Medications and eye comfort
Antibiotics may be prescribed to prevent infection. Short steroid courses reduce inflammation. Artificial tears protect the ocular surface if dryness occurs.
Activity limits and what to avoid
Avoid strenuous activities and heavy lifting for several weeks. Stay away from pools, hot tubs, and saunas for roughly three weeks. Do not get soap or skincare products near incisions until cleared.
Follow-up and sun sensitivity
Follow-up visits usually occur within 1–2 weeks and again as swelling resolves. Incisions remain sun-sensitive; use SPF 30+ and protective sunglasses for months to support scar maturation.
- Timeline: peak swelling 7–10 days; marked improvement in weeks; final settling in months.
- Practical tip: arrange help for the first 48 hours and plan light duties for several weeks.
Benefits and Results: What Patients Can Realistically Expect
Patients typically see both visual and functional gains. Early after healing, the eye often appears more open and the outer corner sits higher. These appearance changes create a smoother eyelid contour and help reduce a rounded or droopy look.
Appearance improvements
A lifted outer corner can produce an almond-like eye shape for some people. Results vary with baseline anatomy and the chosen plan. Small asymmetries are common; true balance is judged after swelling subsides.
Functional benefits
Improved eyelid position can ease irritation and protect the eye surface when laxity caused exposure. Comfort with blinking and tear distribution often improves as support is restored.
Timeline for results
Visible changes are noticeable once swelling and bruising fall—commonly within 7–10 days. Continued refinement happens over subsequent weeks as tissues settle. Final outcomes may take multiple weeks to fully stabilize.
“Early contour is visible quickly; true symmetry and final shape emerge over time.”
- Appearance: lifted outer corner, smoother eyelid line, less droop.
- Function: better eyelid closure, increased comfort, improved eye protection.
- Expectation: modest asymmetry is normal; final results judged after swelling resolves.
| Benefit | What to expect early (7–10 days) | When final result appears |
|---|---|---|
| Outer corner lift | Visible lift as swelling drops | Weeks of tissue settling |
| Eyelid contour | Smoother line, less rounding | Weeks to stable contour |
| Eye comfort | Reduced irritation for many | Improved tear protection over weeks |

Risks, Complications, and How to Choose the Right Surgeon
Understanding risks helps patients weigh benefits and set realistic expectations before eyelid surgery. The list below explains common issues in plain language and shows how to pick a surgeon who lowers your chance of problems.
Common risks
- Infection — may need antibiotics or minor treatment.
- Bleeding — rare but can require return to the clinic.
- Dry eye and light sensitivity — temporary or sometimes longer-lasting.
- Asymmetry — small differences between the two eyes are common.
- Recurrence — drooping can return over time in some cases.
Higher-impact complications
Less common but more serious problems include lid retraction that pulls the eyelid down, tear duct dysfunction, double vision (diplopia), and stitch-related issues. These may need further procedures to fix.
When to seek urgent care
Contact the surgeon or emergency care right away for worsening pain, increasing redness, marked swelling, or fever. These signs can indicate infection or another complication that needs prompt attention.
Why surgeon choice matters
An oculoplastic surgeon is an ophthalmologist with extra training in eyelid, orbit, and tear-system surgery. That expertise reduces the chance of functional problems and unnatural results. ASOPRS membership often signals advanced oculofacial training and focused experience.
Evaluating a provider in the United States
- Confirm board certification and relevant fellowship training.
- Review before/after photos that match your anatomy and goals.
- Look for consistent independent reviews and a clear risk discussion during consultation.
- Ask about revision policy and follow-up care.
Cost and insurance
Cosmetic surgery is usually self-pay. If the surgery is medically necessary, insurance may cover it but often requires documentation and prior authorization. Verify coverage and get a written estimate before scheduling.

Conclusion
Final decisions rest on matching anatomy, realistic goals, and a careful plan for care and follow-up.
Canthoplasty is a targeted procedure that changes outer corner position and improves lower eyelid support for both functional and cosmetic aims.
Patients should compare canthoplasty with canthopexy and blepharoplasty during consultation to confirm candidacy and align the plan with expected results.
Practical steps help the process: complete pre-op labs and medication guidance, arrange transport and home help, and follow post-op instructions closely to support healing.
Expect early swelling and bruising first, with refined results developing over weeks to months. Because this surgery affects comfort and eye protection, prioritize an oculoplastic specialist and understand risks before proceeding.
