One of the first signs of ageing is the skin around the eyes. The Oculoplastic Service at Singapore National Eye Centre shares the types of aesthetic surgeries to help reverse these signs of ageing.

What causes eye bags?
Eye bags occur when fat tissue behind the lower eyelids bulge forward. This happens when the membrane in the eyelid, which holds the fat back, weakens with age, said Dr
Audrey Looi, Senior Consultant and Head,
Singapore National Eye Centre (SNEC), a member of the
Surgery removes eye bags by repositioning the protruding fat, and in some cases, by removing excess skin under the eyes. But doctors are conservative when removing excess skin to prevent the lower eyelid from turning out after surgery – which would expose the inner membrane along the lower edge of the eye.
"We have to judge carefully how much excess skin we can remove, without risking such complications. So, sometimes, there may still be fine lines under the eye after surgery," said Dr Looi.
She said surgeons also avoid the inferior oblique muscle hidden in the fat, as disturbing it can cause double vision. The muscle – located at the base of the eye – is responsible for the movement of the eye. Dr Looi said surgeons take care not to pull excessively on the fat as this can trigger haemorrhage behind the eye and cause visual loss. "This is very rare, but it has been reported in the past when the trend was to remove as much fat as possible."
Surgery for eye bags
There are two different approaches to eye bag surgery.
Transconjunctival approach: A cut is made on the inner lower eyelid through which a bit of fat is removed. There is no scar, so healing is faster. It is suitable for patients in their late 30s to early 40s who have fairly elastic skin and mild bulging of fat. It is also ideal for young thyroid patients with increased fat volume around the eyes.
Subciliary subcutaneous approach: A cut is made below the lower lash line and the inner membrane is opened up. The sagging fat is repositioned. If the lower eyelid is lax, the muscle or tendon of the outer eye corner is tightened for improved support. It is suitable for patients with excess skin, which can be removed as well.
