The lower eyelid is essential to the overall shape and appearance of the eye — and when its lateral attachment becomes lax through aging, genetics, or previous blepharoplasty, the result is a loose, sagging lower lid that produces a tired, sad, or dull-eyed appearance. The lateral canthus — the outside corner where the upper and lower eyelids meet — is the structural anchor that holds the lower lid in its proper youthful position. When the canthal tendon weakens, the lower lid descends, the eye shape rounds out (a condition called rounded canthus), and the lid can appear floppy or lax. Canthopexy and canthoplasty are the two surgical procedures that address this specific structural problem — tightening and reshaping the lateral canthus to restore proper eye shape and lower-lid support. At Los Angeles Plastic Surgery, Dr. John Anastasatos performs canthopexy and canthoplasty at his Beverly Hills practice with the technical precision these intricate eyelid procedures specifically demand.

Dr. Anastasatos performs canthopexy and canthoplasty with the academic surgical credentials these technically demanding procedures specifically reward. Dr. Anastasatos has presented at Cedars-Sinai Medical Center Grand Rounds on advanced surgical techniques — teaching credentials at one of the leading medical institutions in Southern California. He has been an invited lecturer at the Royal Society of Medicine in London on advanced facial surgical techniques, with an invited 2026 return as featured speaker. With over two decades of facial surgical expertise in Beverly Hills since 2007, he is board certified by the American Board of Plastic Surgery, a Fellow of the American College of Surgeons (FACS), a member of the American Society of Plastic Surgeons (ASPS) and American Society for Aesthetic Plastic Surgery (ASAPS), and named by The Luxe Insider as one of the Top 10 Plastic Surgeons in the World.

Understanding the Lateral Canthus

The lateral canthus is the anatomic structure where the upper and lower eyelids meet at the outer corner of the eye. It is held in position by the lateral canthal tendon — a fibrous attachment that anchors the eyelid structure to the orbital bone. When the canthal tendon is youthful and intact, the eye maintains its almond shape with a slight upward tilt at the outer corner. When the tendon weakens, the lower eyelid descends, and the eye begins to lose its defined shape.

The change can be subtle at first — a slight rounding of the eye contour, a barely perceptible looseness of the lower lid. Over time, the change becomes more pronounced: visible scleral show (white of the eye visible below the iris), pronounced rounding, asymmetric eye shape, or a tired, sad expression that no amount of rest can resolve.

Several factors contribute to canthal weakening:

• Genetics — some patients inherit lateral canthal anatomy that becomes lax earlier than typical
• Aging — the canthal tendon naturally weakens over decades, particularly after age 40-50
• Previous blepharoplasty — over-aggressive lower lid surgery can stretch or weaken the canthal support, producing a rounded or loose lid that requires correction
• Asymmetric anatomy — some patients have one eye with significant canthal laxity and another that is normal, producing visible asymmetry

Canthopexy vs. Canthoplasty: The Critical Difference

Both procedures address lower-eyelid laxity at the lateral canthus, but they differ meaningfully in surgical approach, invasiveness, and durability of result.

Canthopexy

Canthopexy is the less invasive of the two procedures. Sutures are used to stabilize and tighten the existing canthal tendon and supporting muscles without cutting or fully detaching the structures. The sutures provide additional support that holds the lower lid in its proper youthful position.

Canthopexy is appropriate for:

• Mild to moderate canthal laxity without significant structural disruption
• Preventive support during routine lower blepharoplasty to avoid post-surgical lid descent
• Patients with minimal scleral show who need modest support rather than full reconstruction

Canthoplasty

Canthoplasty is more intricate and invasive. The procedure involves cutting the lateral canthal tendon or muscle, repositioning it, and surgically reattaching it to the orbital bone in a tighter, more youthful position. This produces more dramatic correction than canthopexy and is more durable.

Canthoplasty is appropriate for:

• Significant canthal laxity with visible eye-shape changes
• Rounded canthus following previous blepharoplasty
• Pronounced scleral show requiring substantial structural correction
• Asymmetric eye shapes needing surgical rebalancing
• Revision lower blepharoplasty correcting prior surgical complications

The choice between procedures depends on the specific anatomic problem, the degree of correction needed, and the durability of result the patient desires.

When Canthopexy and Canthoplasty Are Combined With Other Procedures

Canthopexy and canthoplasty are often performed in conjunction with other cosmetic procedures rather than as standalone operations:

• Combined with blepharoplasty — to provide canthal support during lower lid surgery and prevent post-surgical lid descent
• Combined with revision eyelid surgery — to correct rounded canthus or lower-lid retraction from previous surgery
• Combined with facelift — when comprehensive facial rejuvenation includes lateral canthal tightening for harmonious upper-face refinement
• Combined with brow lift — for coordinated upper-face surgical refreshment

How the Procedures Are Performed

Both canthopexy and canthoplasty are typically performed under local anesthesia with sedation, or under general anesthesia depending on patient preference and combination with other procedures.

For canthopexy, small incisions in the lateral canthal area allow placement of supporting sutures that engage the canthal tendon and tighten the lower lid attachment. The sutures are anchored to the orbital periosteum to provide durable support.

For canthoplasty, the lateral canthal tendon is identified and surgically detached from its current position. The tendon is then trimmed, repositioned, and reattached at a higher and tighter point on the orbital bone. The result is a more dramatic and structurally complete correction.

The procedures take 1-2 hours when performed alone, and adds approximately 30-45 minutes to a combined blepharoplasty.

Recovery and Results

Recovery from canthopexy is typically faster — most patients return to private daily activities within 7-10 days. Canthoplasty recovery is similar but with somewhat more bruising and swelling in the first 7-10 days. Final settling of the result continues over 3-6 months.

Canthopexy results may diminish modestly over time as the supporting sutures lose tension. Canthoplasty results are durable and long-lasting given the structural reattachment of the tendon itself.

Frequently Asked Questions About Canthopexy and Canthoplasty

Will I need canthopexy or canthoplasty during my blepharoplasty?

For some patients, yes. When the lateral canthal anatomy shows pre-existing laxity, prophylactic canthopexy during lower blepharoplasty prevents the post-surgical lid descent that can otherwise occur. Dr. Anastasatos evaluates this specifically during your blepharoplasty consultation.

How are the procedures different from a lower blepharoplasty?

Lower blepharoplasty addresses skin, muscle, and fat in the lower eyelid. Canthopexy and canthoplasty specifically address the canthal tendon — the structural anchor of the lateral lower lid. The procedures address different anatomic problems and are often combined.

Will the eye shape look different after the procedure?

Yes — that is the goal. Canthoplasty in particular can correct rounded canthus and restore a more almond-shaped, youthful eye contour. Patients should expect to see meaningful change in eye shape from these procedures.

Can canthoplasty correct results from previous lower blepharoplasty?

Often, yes. Rounded canthus, lower-lid retraction, scleral show, and ectropion-like changes from previous lower blepharoplasty are common indications for canthoplasty as part of revision eyelid surgery.

Are the scars visible?

The incisions for both procedures are placed at the lateral canthus and within the natural eyelid creases. Once healed, the scars are typically not visible at conversational distance.

How long is the recovery?

Most patients return to private activity within 7-10 days. Visible bruising and swelling resolve over 2 weeks. Final result settling continues over 3-6 months.
