Canthoplasty
What Is Canthoplasty?
The corners of your eyes are held in place by strong bands of tissue called canthal tendons. These tendons attach your eyelids to the bones around your eye socket and keep your lids in the correct position. The outer corner is called the lateral canthus, and the inner corner near your nose is the medial canthus.
When these tendons become stretched, torn, or weak, your eyelids may not sit properly against your eye. This can lead to problems with eye protection, tear drainage, and comfort. Canthoplasty repairs or tightens these important support structures.
Lateral canthoplasty focuses on the outer corner of your eye where your upper and lower lids meet at the side closest to your temple. This is the most common type of canthoplasty and addresses issues with outward-turning lids or lack of support at the outer corner.
Medial canthoplasty works on the inner corner of your eye near the bridge of your nose. We use this less frequently, but it can help with specific conditions affecting the inner eyelid position or tear drainage system.
Because this area includes the tear drainage canaliculi, surgery can affect tearing. In select cases, a temporary silicone stent is placed to protect the drainage system during healing.
Canthoplasty specifically targets the corner attachment points of your eyelids, while other eyelid surgeries work on different structures. Blepharoplasty removes excess skin or fat from eyelids, but does not usually address corner support. Ptosis surgery lifts a drooping upper eyelid by tightening the muscle that raises the lid.
- Canthoplasty repairs or repositions the corner tendon attachments
- It provides structural support rather than just removing tissue
- The procedure often tightens or repositions the canthus, commonly using a lateral tarsal strip sutured to the lateral orbital rim periosteum
- We may combine canthoplasty with other eyelid procedures for complete correction
Reasons You Might Need Canthoplasty
Several medical conditions can damage or weaken the structures at your eye corners. Facial paralysis from Bell's palsy or stroke can cause the lower lid to sag away from the eye. Trauma or injury to the eyelid or eye socket may tear the canthal tendons. Tumors or skin cancers requiring removal of tissue near the eye corner often need canthoplasty for reconstruction.
Some people are born with eye conditions that affect eyelid position, such as Down syndrome or certain genetic disorders. These conditions may cause laxity in the canthal tendons from an early age.
Eyelid malposition means your lid does not sit in its normal position against your eyeball. Ectropion occurs when the lower lid turns outward, exposing the inner lid surface. Entropion happens when the lid turns inward, causing lashes to rub against your eye.
- Both conditions can cause redness, irritation, and excessive tearing
- Long-term malposition may lead to corneal damage from exposure or friction
- Eyelid laxity means the lid has become too loose and lacks proper tension
- Canthoplasty tightens and repositions the corner to restore proper lid alignment
Some patients seek canthoplasty to change the shape or appearance of their eyes for cosmetic reasons. The procedure can alter the slant or width of the eye opening. However, we carefully evaluate whether these changes are safe and will not compromise eye function.
We prioritize maintaining healthy eyelid position and tear film protection over purely aesthetic changes. Any cosmetic canthoplasty must still result in lids that close completely and protect the eye surface properly.
We avoid raising the outer corner beyond your natural anatomy because this can cause lower lid malposition and exposure symptoms.
As we age, the tissues supporting our eyelids gradually lose strength and elasticity. The canthal tendons can stretch over time, causing the lower lid to sag or pull away from the eye. The skin and muscles around the eyes also become thinner and weaker with aging.
These changes may develop slowly over many years, eventually causing symptoms like watering eyes, irritation, or an aged appearance. Canthoplasty can restore the support and position your eyelids once had.
What to Expect During Your Evaluation
Your evaluation begins with a thorough consultation with an oculoplastic surgeon, a doctor who specializes in eyelid and facial plastic surgery around the eyes. During this visit, we will review your medical history, current symptoms, and any previous eye or eyelid surgeries. Be prepared to discuss all medications you take, including blood thinners and supplements.
- Bring a list of your current eye symptoms and how they affect daily life
- Tell us about any eye injuries, infections, or medical conditions
- Share photos if you want to show how your eyes looked before problems started
- Ask about the risks and benefits specific to your situation
We perform a detailed examination of your eyelids, eye corners, and surrounding structures. The doctor will check how tightly your lids sit against your eyes and test the strength of your canthal tendons. We measure eyelid height, position, and movement to determine exactly what needs correction.
The exam also includes checking your eye surface for signs of damage from exposure or irritation. We evaluate your tear production and drainage to see if eyelid position problems have affected these systems.
We may photograph your eyes and eyelids from different angles to document the current condition. These photos help with surgical planning and serve as a comparison for your results after surgery. In some cases, we take specific measurements of eyelid position, eye opening size, and the degree of laxity.
If you had trauma or complex conditions, we might order imaging studies like CT scans to evaluate the bone structure around your eyes. These tests help us plan the safest and most effective approach to your surgery.
If tearing is present or the inner corner is involved, we may test the tear drainage system using dye or irrigation.
We will talk with you about what you hope to achieve from surgery, whether that involves relieving symptoms, improving function, or changing appearance. Your surgeon will explain what canthoplasty can realistically accomplish in your case. We will also discuss whether you might benefit from additional procedures at the same time.
- Alternative treatments like temporary eyelid taping or lubricating drops for mild cases
- Canthopexy as a less extensive option for moderate laxity
- Combined procedures like blepharoplasty or brow lift if needed
- Timeline for surgery and recovery based on your schedule and needs
- Temporizing options such as botulinum toxin for spastic entropion, everting sutures, moisture goggles or eyelid taping, external eyelid weights, or a temporary tarsorrhaphy
The Canthoplasty Procedure
Before your surgery date, we will give you specific instructions to follow. You may need to stop taking certain medications like aspirin or supplements that increase bleeding risk. Do not stop any blood thinners or aspirin-like medicines unless your prescribing clinician approves. Some patients need a temporary bridging plan. If you smoke, we strongly recommend quitting at least several weeks before surgery to improve healing. Arrange for someone to drive you home after the procedure and stay with you for the first day.
On the day of surgery, avoid eating or drinking for the recommended time period before your procedure. Wear comfortable, loose clothing and leave jewelry and makeup at home. Bring your current medications and any paperwork your surgeon requested.
If you receive sedation or general anesthesia, do not drive, drink alcohol, operate machinery, or sign legal documents for at least 24 hours.
Most canthoplasty procedures use local anesthesia with sedation, meaning we numb the area around your eye while you remain relaxed and comfortable. You may receive medication through an IV to help you feel drowsy and calm during the surgery. Some patients prefer or require general anesthesia, where you are completely asleep throughout the procedure.
- Local anesthesia allows faster recovery and fewer side effects
- Sedation levels can be adjusted based on your comfort and anxiety
- General anesthesia may be better for complex cases or combined procedures
- Your medical history and preferences help determine the best option
The surgeon makes a small incision at the outer or inner corner of your eye, depending on which area needs repair. For lateral canthoplasty, we typically perform a canthotomy and cantholysis and create a lateral tarsal strip. The strip is then sutured to the periosteum at the lateral orbital rim near Whitnall's tubercle to restore proper lid tension and angle. For medial canthoplasty, careful work near the tear drainage system may be needed, and a temporary silicone stent may be placed if the canaliculi are involved.
In some cases, we shorten or tighten the lid margin before securing it. The surgeon uses fine sutures to hold everything in place, then closes the skin incision with stitches designed to minimize scarring.
A straightforward canthoplasty on one eye typically takes between 45 minutes and one hour. If we operate on both eyes or combine canthoplasty with other procedures, the surgery may take two hours or longer. Complex reconstructive cases that involve extensive repair may require additional time.
After the procedure, you will spend time in a recovery area where we monitor you as the anesthesia wears off. Most patients go home the same day once they are stable and comfortable.
Recovery and Aftercare
Expect swelling, bruising, and some discomfort around your eyes for the first few days following surgery. Your eyelids may feel tight, and you might notice some oozing from the incision site. We will prescribe or recommend pain medication to keep you comfortable during the early recovery period.
- Plan to rest with your head elevated for the first 48 hours
- Apply cold compresses gently to reduce swelling
- Take all prescribed medications exactly as directed
- Avoid bending over, lifting heavy objects, or straining
- Sleep with extra pillows to keep your head above your heart
- Wear a protective eye shield while sleeping for the first week to prevent accidental rubbing
Swelling and bruising typically peak around two to three days after surgery and then gradually improve. Some people develop black and blue discoloration that spreads to the cheek or other eye. This is normal and will fade over one to two weeks.
Continue using cold compresses several times a day for the first week to manage swelling. After a few days, some surgeons recommend switching to warm compresses. Take pain medication as needed, but contact us if over-the-counter options are not controlling your discomfort.
Use cold compresses 10 minutes on and 10 minutes off during waking hours for the first 48 to 72 hours. Starting day 3, switch to warm compresses 3 to 4 times daily if your surgeon advises. Use preservative-free artificial tears every 2 to 4 hours while awake. Apply a lubricating ointment at bedtime for 1 to 2 weeks, or as directed.
We will provide detailed instructions for cleaning your incision and applying any prescribed ointments. Gently clean the area with the solution we recommend, usually sterile saline or a cleanser your surgeon specifies. Avoid baby shampoo unless your surgeon has asked you to use it. Pat the area dry with a clean tissue or gauze after cleaning. Do not use hydrogen peroxide, alcohol, or harsh cleansers on the incision.
Apply antibiotic ointment if prescribed to prevent infection and keep the wound moist. Avoid getting the surgical site wet in the shower for the first few days, and do not submerge your head in water until we tell you it is safe.
For the first week, avoid any strenuous activity, heavy lifting, or exercise that raises your blood pressure. Do not rub your eyes or pull on your eyelids. You can usually return to desk work and light activities within a few days to a week, depending on how you feel.
- Wait at least two weeks before resuming vigorous exercise or sports
- Avoid contact sports or activities with injury risk for four to six weeks
- Wear sunglasses outdoors to protect your eyes from sun and wind
- Follow our specific guidelines about wearing makeup and contact lenses
- Avoid blowing your nose forcefully for 2 weeks if the inner corner was treated or if your surgeon advises
- Do not wear eye makeup or contact lenses until your surgeon says it is safe, usually after 1 to 2 weeks
- Protect healing scars from sun with sunglasses and broad-spectrum SPF 30 or higher for at least 6 months
Your first follow-up appointment typically occurs within one week after surgery so we can check your healing and remove any non-dissolving stitches. Most external sutures are removed at 5 to 10 days. Some deep sutures dissolve on their own. We will examine the surgical site for signs of infection or problems and make sure your eyelid is healing in the correct position. Additional visits are scheduled over the following weeks and months to monitor your progress.
Report any concerns between appointments rather than waiting for your next scheduled visit. We want to catch and address any issues as early as possible to ensure the best outcome.
Most of the swelling and bruising resolves within two to three weeks, but subtle swelling may persist for several months. The final results of your canthoplasty become apparent once all healing is complete, usually around three to six months after surgery. Your eyelid often maintains its improved position and support for many years.
The longevity of your results depends on factors like your age, tissue quality, and whether the underlying cause has been fully corrected. In some cases, aging or other factors may eventually cause some laxity to return, but most patients enjoy long-lasting benefits from the procedure.
Risks and Complications to Know About
Nearly all patients experience some degree of swelling, bruising, and mild discomfort after canthoplasty. These side effects are temporary and expected as part of normal healing. Your eye may water more than usual at first, or you might notice some dryness or grittiness.
- Temporary blurred vision from ointments or swelling
- Sensitivity to light for the first few weeks
- Mild asymmetry between eyes during the healing process
- Numbness or altered sensation around the surgical site
Infection is uncommon but can occur after any surgery. Signs include increasing redness, warmth, pain, or drainage from the incision site, especially if accompanied by fever. Contact us immediately if you notice these symptoms. We may prescribe antibiotics to treat an infection.
Scarring is inevitable with any surgical incision, but our techniques minimize visible marks. Most scars fade significantly over time and blend into the natural creases at your eye corner. Poor healing can result in thickened or noticeable scars in some patients, though this is uncommon at the eyelids and true keloids in this area are rare.
Canthoplasty alters the position of your eyelid corner, which affects the overall shape of your eye opening. In some cases, the change may be more or less than anticipated, or one eye may heal differently than the other. Minor asymmetry is common since most people have slightly different eyes to begin with.
Rarely, overcorrection can create an overly tight or rounded eye appearance, while undercorrection may not fully resolve the original problem. If significant asymmetry or shape concerns persist after complete healing, we may discuss revision surgery options.
- Lower lid retraction or rounding of the outer corner (lateral webbing)
- Persistent or recurrent ectropion or entropion
- Need for revision surgery if position or symmetry is not satisfactory after healing
Additional complications can affect eyelid function and structure after canthoplasty. We will discuss your individual risk factors during your consultation.
- Corneal abrasion or exposure keratopathy from incomplete blinking or closure
- Problems with tear drainage (watering), especially after medial canthoplasty or canalicular injury
- Lateral canthal rounding or webbing, lid notching, or lower lid retraction
- Recurrence of laxity or malposition over time
Contact our office or seek immediate medical attention if you experience sudden vision loss, severe eye pain that does not improve with medication, or significant bleeding from the surgical site. Other urgent symptoms include signs of infection like fever, rapidly worsening swelling, or pus draining from the incision.
- Sudden vision changes or loss of vision in the operated eye
- Severe pain not controlled by prescribed medications
- Heavy bleeding or large blood clots under the skin
- Fever above 101 degrees Fahrenheit
- The eyelid will not close or the eye feels extremely dry and painful
- A firm, rapidly worsening swelling around the eye with bulging, severe pain, or new vision changes, which can be a sign of bleeding behind the eye
- If you cannot reach us promptly, call emergency services
Frequently Asked Questions
Canthoplasty results are generally long-lasting, and many patients maintain their improved eyelid position for many years or permanently. However, the natural aging process continues after surgery, and some laxity may gradually return over time. The procedure provides much more durable correction than non-surgical options, but no surgery can completely stop the effects of aging on your tissues.
Insurance typically covers canthoplasty when it is medically necessary to correct functional problems like ectropion, entropion, or eyelid malposition causing eye damage or significant symptoms. Purely cosmetic canthoplasty performed only to change eye shape is usually not covered. Your surgeon's office can help determine your coverage by submitting documentation of your medical need to your insurance company before surgery.
Yes, we frequently combine canthoplasty with other eyelid or facial surgeries to achieve comprehensive results in a single operation. Common combinations include blepharoplasty to remove excess skin, ptosis repair to lift a drooping upper lid, or brow lift procedures. Combining surgeries reduces your total recovery time compared to staging procedures separately, though it does make each individual surgery longer.
The cost of canthoplasty varies widely based on your location, the complexity of your case, and whether other procedures are performed at the same time. Medically necessary canthoplasty may be covered by insurance after you meet your deductible and copayments. For cosmetic procedures or portions not covered by insurance, costs can range from several thousand dollars to more, and your surgeon's office can provide a detailed estimate during your consultation.
Canthopexy is a less extensive procedure that tightens the canthal tendon without detaching it from the bone. We use canthopexy for milder cases of eyelid laxity where the tendon position is acceptable but needs reinforcement. Canthoplasty involves actually detaching the tendon and repositioning it to a new location on the bone, making it appropriate for more severe laxity or when significant position change is needed.
The incisions for canthoplasty are placed at the natural creases of your eye corners where scars blend in with existing lines and shadows. Most patients find their scars quite inconspicuous once fully healed. Initially, scars may appear pink or red, but they typically fade to thin white lines over several months to a year. Proper wound care and sun protection during healing help minimize scar visibility.
Getting Help for Canthoplasty
If you are experiencing eyelid position problems, irritation, or other symptoms that may benefit from canthoplasty, we encourage you to schedule a consultation with an oculoplastic surgeon. This specialist can evaluate your condition, discuss whether you are a good candidate for the procedure, and create a personalized treatment plan to restore both the function and appearance of your eyelids. Whenever possible, choose a board-certified ophthalmologist with oculoplastic subspecialty training for this procedure.
