Scleral Show After Blepharoplasty

Scleral show after blepharoplasty refers to increased visibility of the white part of the eye, particularly below the iris, after eyelid surgery. While a small amount of lower scleral show can be a natural facial characteristic, a noticeable increase after surgery may indicate changes in lower eyelid position or support.

In Korean eye plastic surgery, surgeons carefully evaluate lower eyelid anatomy, eyelid tone, and facial structure before lower blepharoplasty to minimize the risk of postoperative scleral show. Understanding why it occurs helps patients make informed decisions about eye bag surgery, fat repositioning, and revision procedures.

What Is Scleral Show?

Scleral show describes the visible area of the sclera, or the white part of the eye, between the lower eyelid margin and the iris.

A small amount of scleral visibility may be completely normal. However, increased scleral show can make the eyes appear:

• More open or round
• Surprised or startled
• Less relaxed
• Less balanced with the face

The degree of scleral show depends on eyelid position, eye shape, and surrounding facial anatomy.

Why Can Scleral Show Occur After Blepharoplasty?

After lower blepharoplasty, scleral show may occur when the lower eyelid sits lower than its original position.

Possible causes include:

• Excessive lower eyelid skin removal
• Weak lower eyelid support
• Scarring and tissue tightening
• Lower eyelid retraction
• Insufficient canthal support
• Negative vector facial anatomy

Proper surgical planning helps reduce these risks.

Lower Eyelid Retraction and Scleral Show

Lower eyelid retraction is one of the main causes of increased scleral show after surgery.

It occurs when the lower eyelid is positioned too low, causing:

• More white eye exposure
• A rounded lower eyelid shape
• Increased lower eyelid height

Patients may also experience:

• Dryness
• Eye irritation
• Difficulty closing the eyes comfortably

Scleral Show After Lower Blepharoplasty

Lower blepharoplasty is designed to improve:

• Eye bags
• Under-eye fat bulging
• Loose lower eyelid skin

However, aggressive tissue removal or insufficient support correction may affect eyelid position.

Modern lower blepharoplasty techniques often emphasize:

• Fat preservation
• Fat repositioning
• Conservative skin removal
• Lower eyelid support evaluation

This approach helps maintain a natural eyelid contour.

Risk Factors for Postoperative Scleral Show

Certain patients may have a higher risk of developing scleral show after blepharoplasty.

Risk factors may include:

• Naturally prominent eyes
• Negative vector eyes
• Weak lower eyelid tone
• Lower eyelid laxity
• Previous eyelid surgery
• Excessive skin removal
• Significant midface volume deficiency

A detailed preoperative assessment helps identify these factors.

Scleral Show and Negative Vector Eyes

Negative vector anatomy can influence lower eyelid stability because the eyeball projects farther forward than the cheek.

This may create:

• Less lower eyelid support
• Greater tension on the lower eyelid
• Higher sensitivity to surgical changes

Patients with negative vector eyes may require additional planning, such as:

• Fat repositioning
• Canthal support procedures
• Midface volume enhancement

How Surgeons Evaluate Scleral Show Risk Before Surgery

Before blepharoplasty, surgeons assess several factors, including:

• Lower eyelid snap test
• Eyelid distraction test
• Canthal tendon strength
• Eye prominence
• Cheek projection
• Skin elasticity
• Existing scleral show

These evaluations help determine the safest surgical technique.

Preventing Scleral Show During Blepharoplasty

Surgeons may use several strategies to reduce the risk of postoperative scleral show.

These may include:

Conservative Skin Removal

Avoiding excessive removal helps maintain lower eyelid flexibility and position.

Fat Repositioning

Moving lower eyelid fat into tear trough areas can improve contour without creating excessive hollowing.

Canthal Support

Procedures such as canthopexy or canthoplasty may strengthen lower eyelid support when needed.

Midface Support

For patients with reduced cheek support, improving midface volume may help create a smoother eyelid-cheek relationship.

Temporary vs Permanent Scleral Show

Not all scleral show after surgery is permanent.

Temporary Scleral Show

Early after surgery, it may occur due to:

• Swelling
• Tight tissues
• Muscle stiffness
• Temporary eyelid position changes

It may gradually improve as healing progresses.

Persistent Scleral Show

If scleral show remains after tissues have healed, it may be related to:

• Lower eyelid retraction
• Scar contraction
• Structural support issues

Further evaluation may be needed.

Revision Surgery for Scleral Show

Revision lower eyelid surgery focuses on restoring eyelid support and improving position.

Possible approaches may include:

• Scar release
• Lower eyelid repositioning
• Canthopexy or canthoplasty
• Spacer graft procedures
• Fat grafting
• Midface lifting techniques

The best option depends on the cause of the scleral show.

Scleral Show in Asian Eyelid Surgery

Asian patients may have different eyelid and orbital characteristics that influence lower eyelid appearance.

Surgeons consider:

• Orbital shape
• Lower eyelid thickness
• Tear trough structure
• Midface projection
• Eye prominence

Korean eye surgeons often focus on preserving natural eye proportions rather than maximizing eye opening.

Final thoughts

Scleral show after blepharoplasty is an important consideration in lower eyelid surgery because it can affect both appearance and eye comfort. While a small amount of scleral visibility may be natural, excessive exposure may result from lower eyelid position changes, insufficient support, or aggressive tissue removal. Through detailed evaluation of eyelid structure, facial vectors, and surgical technique, Korean eye surgeons aim to create balanced lower eyelid results while maintaining natural eye function.
