Eyelid Surgery

General definition and anatomical context

Eyelid surgery — known medically as blepharoplasty — is the surgical correction of excess skin, displacement of the fat compartments and muscle laxity in the upper and lower eyelids. Among the various facial aesthetic procedures, it is one of the few that can deliver both aesthetic and functional results at the same time; in advanced sagging, excess upper lid skin can genuinely narrow the field of vision.

The anatomy around the eye packs a dense structure into a small area:

• Upper eyelid skin: the thinnest skin in the body, it loses its elasticity quickly.
• Orbicularis muscle: the ring-shaped muscle surrounding the eye, responsible for blinking and facial expression.
• Septum and fat compartments: a thin membrane that holds the fat pockets within the eye socket; it weakens with age and allows the fat to herniate forward.
• Tarsal plate: the firm cartilage-like structure that forms the inner framework of the lid.
• Levator muscle: the muscle that raises the upper lid; in true cases of ptosis there is weakness in this muscle.

From an aesthetic standpoint, the area around the eyes is the first part of the face that is read; even small changes therefore make a marked difference in the shift from a tired expression to a rested one.

When it is considered

The following findings may be a reason to consider eyelid surgery:

For the upper eyelid

• Excess skin on the upper lid (dermatochalasis), drooping over the lashes
• Narrowing of the upper part of the visual field due to skin (functional indication)
• Make-up that no longer sits in the crease and smudges downward
• Asymmetric lid contours
• A heavy lid that has developed together with mild brow descent

For the lower eyelid

• Prominent fat herniations (bags) under the eye
• Excess skin and fine lines
• Marked fullness in the tear trough (the hollow below the eye) and the transition to the cheek
• Under-eye bags that become prominent at an early age for genetic reasons
• Dark circles (surgery is not always the solution — pigmentary darkness requires a different treatment)

The treatment plan changes in conditions such as glaucoma, dry eye, thyroid eye disease and skin infections. In patients with advanced dry eye, the picture may temporarily worsen after surgery; for this reason an ophthalmology consultation may be recommended.

The ageing process and its causes

The area around the eyes is one of the fastest-ageing regions of the face. This is because several layers are affected at the same time.

Skin thinning

The upper lid skin is the thinnest in the body (around 0.5 mm). The loss of collagen shows its effect early in this area; in most people, fine lines and mild sagging begin from the mid-thirties onward.

Fat compartment herniation

As the orbital septum membrane — which holds the fat pockets within the eye socket forward — weakens, the fat herniates forward. This is seen as bagginess in the lower lid and fullness on the inner aspect of the upper lid.

Deepening of the tear trough

As the cheek fatty tissue shifts downward with age, the hollow below the eye (the tear trough) deepens. The result is a tired, “hollowed” under-eye appearance.

Orbicularis muscle laxity

As the muscle around the eye becomes lax, the lid margin curls and the lower lid may turn slightly outward (ectropion).

Genetic predisposition

In some people, under-eye bags become prominent in their twenties to thirties; this is not ageing but an anatomical predisposition, and it is corrected with the same procedure.

Lifestyle and external factors

Irregular sleep, chronic stress, allergy, alcohol use and excessive salt intake produce temporary swelling around the eyes. These are different from genuine structural change; however, when they become a long-standing habit they can also affect skin elasticity. Distinguishing whether the bagginess that appears in a young patient is structural or lifestyle-related determines the treatment plan.

Screen use

Prolonged screen use increases dryness of the eyes, fatigues the expression muscles and may cause crow’s feet and a tired appearance around the eyes to become prominent at an early age.

Diagnosis and assessment process

The initial examination for eyelid surgery is a more comprehensive assessment than expected. An experienced plastic surgeon examines the following:

• The degree of upper lid excess skin and the presence of true ptosis (levator muscle weakness)
• Brow position — if the brow has descended, a lid operation alone may not be enough; a brow lift may also be required
• The snap test and distraction test to assess skin–muscle tone in the lower lid
• Which compartment the fat herniations are in (inner, middle, outer)
• Tear trough depth and the transition to the cheek
• Dry eye complaints and the tear film test
• Visual field testing (if required for a functional indication)

A distinction must be made between pigmentary dark circles, vascular darkness and genuine structural bagginess — because surgery resolves only structural problems; topical treatment is more appropriate for pigment, and filler for vascular darkness.

Other points an experienced plastic surgeon assesses at the initial examination:

• Previous aesthetic interventions (filler, laser, peeling, botox)
• Family history — under-eye bags are often genetically inherited
• Use of contact lenses or glasses
• History of allergy (allergic swelling must be distinguished from genuine bagginess)
• Social impact: how a tired expression affects daily life

These answers are important in determining the right timing; in some people, allergy or dry eye should first be brought under control, and surgery considered afterward.

Treatment approaches

There is no single technique in eyelid surgery; rather, there are approaches selected according to the findings.

Non-surgical and minimally invasive options

• Hyaluronic acid fillers: in selected cases for the tear trough region; they fill the under-eye hollow. They are not suitable in cases with prominent fat herniation.
• Botulinum toxin: for crow’s feet, used in measured amounts in those with lower lid muscle hypertrophy.
• Laser / chemical peeling: skin resurfacing for fine lines; it does not replace surgery.
• Radiofrequency: mild skin tightening.

Surgical methods

Upper eyelid blepharoplasty

The incision is made in the natural eyelid crease, so that the scar is unnoticeable once the sutures are removed. Excess skin, a strip of orbicularis muscle when required and herniated fat are removed. If there is ptosis, the levator muscle is repaired in the same session.

Lower eyelid blepharoplasty

Two main approaches are used according to the findings:

• Transconjunctival approach: the incision is made on the inner surface of the lid, leaving no external scar. The fat herniations are removed or redistributed. It is ideal in young cases with a genetic predisposition and little excess skin.
• Subciliary approach: excess skin is also removed through an incision beneath the lashes. It is necessary in cases with marked skin sagging. The scar is hidden in the lash line.

Fat-preserving approaches

In modern surgery, the fat compartments in the lower lid are not simply removed; they are also redistributed (fat repositioning) into the tear trough region to fill the under-eye hollow. This prevents an “empty and sunken” appearance.

Combined procedures

The upper and lower lids can be treated in the same session; a brow lift, facelift or mid-face lift can be planned within the same operation. In a person whose upper lid appears to be sagging, it often becomes clear at the initial examination that the real problem is brow descent; in such a case an upper lid operation alone will not permanently resolve the problem, and a brow lift should also be assessed.

Asian eyelid surgery

The Asian eyelid is anatomically different: in most people the lid crease is indistinct or absent. Blepharoplasty intended to alter this structure is a different technique from creating a classic Western-type lid crease and should be planned with respect for the person’s ethnic characteristics.

Process and recovery

Eyelid surgery — on the upper lid alone — is most often a 1-2 hour procedure performed under local anaesthesia with sedation. When the upper and lower lids are treated together, or combined with other procedures, general anaesthesia may be preferred. The procedure ends with same-day discharge.

The first 48 hours

• Mild swelling and bruising are to be expected.
• Cold compresses markedly reduce the swelling.
• Sleeping with the head elevated (1-2 pillows) is recommended.
• The antibiotic/lubricating drops recommended by the doctor are used regularly.

The first week

• Sutures are removed on days 5-7.
• Rubbing the eyes and prolonged time in front of a screen are limited.
• A return to light reading and indoor activity is possible.

The second week

• Bruising largely subsides; it can be covered with make-up.
• A return to social life begins during this period.
• Contact lens use is resumed with the doctor’s approval.

Weeks 3-6

• Swelling subsides completely; the eyelid crease settles.
• A return to sport is undertaken with the doctor’s approval.

Months 3-6

• The scars fade and the tissue settles completely.
• The final result is read during this period.

In recovery, the main risk factors are smoking, uncontrolled blood pressure and blood thinners such as aspirin. Blood thinners are stopped at least 2 weeks before the operation, with the doctor’s approval. During the same period, alcohol, vitamin E and certain herbal supplements are also discontinued, as they increase the tendency to bleed.

Throughout the first week, the use of a cold compress around the eyes is the single most effective method for reducing swelling; it is applied for 10-15 minutes every two hours. Artificial tear drops are used regularly for the first 2-4 weeks; this reduces the temporary dry eye sensation in the lower lid.

Managing expectations and quality of life

Eyelid surgery is a procedure with a small but high impact. In a person who is constantly met with the question “you look tired,” a single session can visibly change how others read their expression.

The results are maintained for 7-10 years in the upper lid and often for a lifetime in the lower lid — because the fat that is removed does not return. Skin ageing continues, however; sun protection and skin care are therefore decisive in the longevity of the result.

In managing expectations, one point must be underlined: eyelid surgery is not performed to change the colour or shape of the eye or the character of the gaze. The surgery provides a rested frame for the person’s own eyes. Seeking to radically change the shape of the lid (such as an outer-corner lift or an almond eye shape) is a different indication and a different procedure.

In people with dry eye complaints, a temporary flare-up after the procedure can be expected; for this reason it is important to share complaints honestly during the pre-operative assessment.

In surgery around the eye, a poor result is most often the product of an overly aggressive approach: removing too much skin causes the lower lid to turn outward (ectropion); removing too much fat causes a sunken “hollow eye” appearance. For this reason, in the modern approach to blepharoplasty, the question “how little intervention will be enough” comes before the question “how much can I correct.”

How the post-operative period will be managed in social life should be planned in advance. Staying away from environments that require high visibility — such as intensive meetings, stage or camera appearances — for the first 2 weeks is important both for psychological comfort and for the quality of recovery.

When to consult a specialist

The following situations make a consultation sensible:

• A tired look persists even after waking in the morning
• Sagging of the upper lid prevents make-up from sitting or narrows the field of vision
• Under-eye bags do not resolve with weight loss or a good night’s sleep
• Prominent bags are present at a young age (genetic predisposition)
• There is asymmetry or one-sided sagging

In the consultation, a specialist answers whether surgery is genuinely necessary for the person’s condition, or whether skin care, filler or treatment should take priority. The choice of the right timing and the right technique is decisive in the durability of the result; in surgery around the eye, the principle of “little and careful” always applies.
