Lateral Canthoplasty (Outer Corner Surgery) Explained
Lateral Canthoplasty (Outer Corner Surgery) Explained
Lateral canthoplasty—often called outer corner eye surgery—is a procedure designed to modify the outer corner of the eyes to create a wider, longer, or slightly lifted appearance. In Korea, it is commonly performed as part of eye shape refinement rather than a standalone cosmetic change.
Because the outer eye corner plays a major role in eye expression and stability, proper indication and technique are essential.
What Is Lateral Canthoplasty?
Lateral canthoplasty involves surgically adjusting the lateral canthus, the point where the upper and lower eyelids meet at the outer corner of the eye. The procedure can:
- Lengthen the horizontal eye width
- Reduce a slanted or upturned eye shape
- Create a softer or more open eye appearance
It differs from lateral canthotomy, which is a simpler release technique and generally offers limited, less stable results.
Why Lateral Canthoplasty Is Performed
Patients may consider lateral canthoplasty for:
- Short or narrow eye appearance
- Upward-slanted outer eye corners
- Desire for longer, more balanced eye shape
- Asymmetry between both eyes
In Korea, it is often combined with double eyelid surgery or epicanthoplasty for balanced results.
How Lateral Canthoplasty Is Performed
During surgery:
- A small incision is made at the outer eye corner
- The eyelid attachment is carefully repositioned
- The outer corner is secured at a new angle or position
Proper fixation is critical to prevent relapse or instability. Most procedures are performed under local anesthesia.
Benefits of Lateral Canthoplasty
- Creates a longer and more open eye shape
- Softens sharp or overly upturned eyes
- Enhances symmetry when combined with other eye surgeries
- Can subtly lift the outer eye area
When done correctly, results appear refined rather than dramatic.
Limitations and Risks
Lateral canthoplasty is not suitable for everyone. Potential limitations include:
- Limited change if eye anatomy is restrictive
- Risk of relapse if fixation is weak
- Temporary tightness or dryness during healing
Over-aggressive surgery can lead to:
- Unnatural eye shape
- Outer corner instability
- Visible scarring
This is why conservative design and surgeon experience are crucial.
Recovery and Healing
Typical recovery includes:
- Swelling and mild discomfort for 1–2 weeks
- Gradual softening of the outer corner over time
- Final stabilization within 2–3 months
Temporary tightness or pulling sensation is common and usually resolves as tissues heal.
Who Is a Good Candidate?
Lateral canthoplasty may be suitable for:
- Patients with sufficient outer eye corner structure
- Individuals seeking subtle eye widening
- Patients undergoing combined eye surgery
It may not be recommended for those with:
- Severe dry eye
- Weak lower eyelid support
- Unrealistic expectations for dramatic enlargement
A detailed in-person evaluation is essential.
Importance of Surgical Experience
The outer eye corner is structurally delicate. Surgeons experienced in lateral canthoplasty focus on:
- Maintaining eyelid stability
- Preserving natural eye movement
- Avoiding excessive lowering or pulling
In Korea, surgeons often prioritize long-term stability over maximum change.
Final Thoughts
Lateral canthoplasty is a nuanced procedure that can enhance eye shape when properly indicated and conservatively performed. While it can create a wider and softer appearance, it requires precise technique and realistic expectations.
Choosing an experienced surgeon and understanding anatomical limitations are key to achieving natural, stable, and balanced results.
