A drooping upper eyelid can do more than affect appearance. In some cases, it may obstruct vision, cause eye strain, or make the eyes appear tired and heavy. Dr Colin Tham assesses the cause and severity of the eyelid droop before performing ptosis correction surgery to elevate the upper eyelid, improve visual function where affected, and restore a more natural, balanced eyelid position.

Ptosis correction surgery is a procedure that lifts a drooping upper eyelid by adjusting the muscles and structures responsible for eyelid elevation. Depending on the cause and severity of the ptosis, surgery may involve tightening, repositioning, or supporting the levator muscle, which lifts the upper eyelid.
Patients who undergo ptosis correction surgery may experience:
The most suitable surgical approach depends on factors such as the degree of eyelid drooping, levator muscle function, eyelid measurements, and whether one or both eyelids are affected.
Although these procedures all involve the upper eyelids, they are designed to address different concerns and achieve different outcomes.
Elevates a drooping upper eyelid by addressing the eyelid-lifting mechanism to improve eyelid position and visual function where affected.
Creates or enhances an upper eyelid crease to improve eyelid definition and appearance.
Some patients may have a combination of eyelid concerns, such as ptosis and excess upper eyelid skin. In these cases, a combination of procedures may be recommended to address both functional and aesthetic concerns.
Ptosis is a condition in which the upper eyelid droops lower than its normal position. It may affect one or both eyes and can range from mild to severe. In some cases, ptosis may cause the eyes to appear tired or heavy, while more significant drooping can partially obstruct the field of vision and interfere with daily activities.
Types of Ptosis
Measurements Used During Assessment
To determine the cause and severity of ptosis, Dr Colin Tham performs a detailed assessment of the eyelids, including measurements that help guide treatment planning and surgical approach.
MRD measures the distance between the centre of the pupil and the upper eyelid margin. This helps assess the degree of eyelid drooping.
This measures how effectively the levator muscle lifts the eyelid. The results help determine the severity of the ptosis and guide the choice of surgical technique.
Several surgical techniques may be used to correct ptosis. The most appropriate approach depends on the underlying cause of the eyelid droop, the severity of the ptosis, and the function of the eyelid-lifting muscles.
The external approach is commonly used when the levator muscle retains adequate function. Through an incision placed within the natural eyelid crease, the levator tendon is tightened or repositioned to improve eyelid height and symmetry. The incision is concealed within the eyelid crease, helping to minimise visible scarring.
The internal approach may be suitable for selected patients with mild ptosis and good levator muscle function. The procedure is performed through an incision on the inside of the eyelid, leaving no visible external scar. By adjusting structures that contribute to eyelid elevation, the eyelid position can be improved while maintaining a natural appearance.
Frontalis suspension is typically reserved for severe congenital ptosis or cases where the levator muscle has poor function. The procedure uses a sling material to connect the eyelid to the forehead muscle (frontalis muscle), allowing the forehead muscle to assist in lifting the eyelid. This approach may be considered when conventional levator-based techniques are unlikely to achieve adequate eyelid elevation.
Your consultation will include an assessment of eyelid position, levator muscle function, eyelid symmetry, and the degree of visual obstruction caused by the ptosis. These findings help determine whether surgery is appropriate and which surgical technique may be most suitable.
You will also have the opportunity to discuss your treatment goals, expected outcomes, recovery process, and any potential risks associated with the procedure.
Ptosis correction surgery is typically performed under local anaesthesia and may take approximately 1 to 2 hours, depending on the complexity of the procedure and whether one or both eyelids are being treated.
The incision may be placed within the natural eyelid crease or on the inside of the eyelid, depending on the surgical technique used. Once the necessary adjustments have been made, the incision is closed with sutures or surgical adhesive.
Swelling, bruising, and mild discomfort are common during the initial recovery period and generally improve over the first 1 to 2 weeks. Temporary tearing, dryness, or blurred vision may also occur.
Most patients can return to light daily activities within a few days, although recovery timelines vary between individuals. Follow-up appointments are important to monitor healing, assess eyelid position, and address any concerns during recovery.
Recovery Stage | Typical Timeline |
|---|---|
| Swelling and bruising | 1–2 weeks |
| Return to light activities | A few days |
| Follow-up review | As advised by your surgeon |
Ptosis correction surgery may be considered for individuals with a drooping upper eyelid that affects vision, eyelid symmetry, or overall appearance. As the underlying causes and severity of ptosis can vary, a detailed assessment is important to determine whether surgery is appropriate and which surgical approach may be most suitable.
At Colin Tham Plastic Surgery, treatment plans are tailored to each patient's eyelid anatomy, functional concerns, and aesthetic goals. From diagnosis and surgical planning to recovery and follow-up care, patients receive personalised guidance throughout the treatment journey. If you are considering ptosis correction surgery, schedule a consultation to discuss your concerns and treatment options with us today.
Mild cases of ptosis may be managed with non-surgical methods like prescription eye drops or ptosis crutches. However, these non-surgical options can only provide temporary relief as they may not address the underlying cause of the eyelid droop.
Surgery is often the most effective treatment for more severe cases and for long-lasting results.
As with any surgical procedure, ptosis correction surgery carries potential risks and complications. These may include bruising, swelling, bleeding, infection, scarring, asymmetry, under-correction, overcorrection, dry eye symptoms, temporary blurred vision, difficulty closing the eyelid, and the need for revision treatment.
You should seek medical attention promptly if you experience increasing pain, worsening swelling, heavy bleeding, fever, sudden vision changes, severe headache, or symptoms that feel unusual during recovery.
