Welcome to Alex Ooi Associates

 Established on 12 July 1982, the clinic was completely renovated and upgraded in June 2003 with the latest state of the art equipment. Over the years, it has continually expanded its services to ensure the best care possible for all aspects of Obstetrics and Gynecology.

In 2005, Gyne-Aesthetic services were added – using the latest O2-jetpeel, lasers, natural supplements and office tumescent local anesthesia liposuction (TLS) / fat transfer (FT) for skin care, fat management, life-enhancing age-care and safe, effective body sculpting.

Besides personalized quality care at affordable prices, the doctors and staff provide a professional and comforting environment. We do our best to allay your anxieties whilst tending to your concerns. Our doctors speak English, Indonesian, Mandarin & some dialects. Japanese translation is available.

Consultation, most investigations and clinic day-surgery can be done at the same visit for quick turnaround, minimal inconvenience/anxiety and cost reduction. Comprehensive (PAP smear, ultrasound, tests, etc) annual care is provided in a confidential setting. Please keep to your appointment time to help us reduce waiting time for everyone.
The full range of services is provided, in conjunction with other specialists when necessary. The latest diagnostic equipment is used, e.g., fetal, breast and bone ultrasound, colposcopy for abnormal PAP smear/cancer, hysteroscopy/thermablation for heavy menses, body composition analysis.

Most surgery, where indicated, is performed in the clinic’s well-equipped operating room. More major surgery is performed in Mount Elizabeth or other hospitals of your choice.
Lasers, including laser vaginal rejuvenation and reconstruction, are used judiciously in procedures which will be enhanced by its use. Our doctors practice “key-hole” surgery where appropriate – for less pain and faster recovery.

Our Mount Elizabeth Medical Centre (MEMC) houses over 350 specialists from all disciplines, a true a one-destination stop. Well located behind Paragon Shopping Centre and Lucky Plaza along Singapore's main road, Orchard Road, it is backed up by the Mount Elizabeth Hospital, a tertiary care institution of repute. It is easily accessible and known to all taxi drivers. There are a lot of hotels, apartments and eating places of varying price ranges within walking distance. We can assist you with looking for accommodation.

Dr Alex Ooi is a senior obstetrician and gynecologist. He has served on the Mount Elizabeth Hospital Medical Advisory Board and was Chairman on the Minimal Access [“keyhole”] Surgery group which revamped the dedicated operating theatres and initiated educational activities in this fascinating field of surgery. He has also been visiting consultant to Fudan University in Shanghai and several other hospitals in the region.

Since early 2005, he established tumescent liposuction services at his clinic as a natural extension of his expertise in keyhole surgery – devoting time for performance of no more than two liposuction surgeries a week. Together with Dr Lucy Ooi, a limited range of proven cosmetic services is also offered at his clinic.

Rejuvenation & acne, pigment, pore-size treatment


Body fat increases gradually over the years. After 30, fat accumulates according to a genetically predetermined pattern, such as the fat that appears on the abdomen, hips and thighs of a woman and abdomen and ‘love handles’ of a man. Sometimes, abnormal fat location is inherited.

Such fat, often impossible to eliminate by exercise or dieting, can now be removed by TLS - the only realistic means of focusing the effects of dieting to specific areas.


TLS is the suction removal of over 50% of the excess fat between skin and muscle by thin cannulas through small skin incisions. An improved body contour comes from collapse of the resulting tiny tunnels created.

The most frequently treated areas in women are the abdomen, hips, thighs, arms and beneath the chin. In men, the ‘love handles’, abdomen, breasts, neck and chin.

The word ‘tumescent’ means swollen and firm - made so by means of a dilute salt solution of local anesthetic and vessel constrictor. The result is an antibacterial, pain free and bloodless environment for suction of loosened fat.

Removed fat cells do not grow back. As long as there is no excessive weight gain, the new, confidence enhancing silhouette is permanent. For those who gain weight post-surgery, the treated areas maintain the new desirable silhouette whereas untreated areas would be the sites of new fat deposits. We can help you with a good diet-exercise regime for long-term health and beauty.


The best are those in good health and have realistic expectations. Most have localized accumulations of fat. Cosmetic success comes from loss of inches rather than pounds.

Note that TLS is not a last resort treatment for increasing obesity. However, the ‘stable’ obese with certain problem areas of fat, may be excellent candidates.


Traditional liposuction carries some risks associated with the use of larger instruments and general or epidural anesthesia.

In TLS, delivering the anesthetic only to the areas for treatment and in a safe, effective dose is much safer – without need for hospitalization or blood transfusion and with no serious infections or complications. Sleep anesthesia is provided to allay anxiety.

Minor surgical problems like mild bruising, swelling and temporary numbness occur buyt these discomforts are easily manageable.

The clinic is a Singapore Medical Council Licensed & Medisave Certified Surgery adjoining Mount Elizabeth, a renowned tertiary care hospital.


Surgery is essentially painless once the area is numbed and, because numbness persists for over 12 hours, there is also no pain after. General anesthesia does not provide this and does not permit patients walking home soon after surgery.

The TLS technique magnifies the fatty area, allowing for a more even and thorough liposuction, resulting in less post-surgical irregularities, unevenness and cellulite.

The use of vibration power and micro-instruments makes the surgery less forceful and much less traumatic to other structures and dermis – with better healing. The small wounds heal readily and, especially if well hidden, usually become invisible. Adjunct laser therapy is used to speed healing further.

Because it takes more time to infuse the local anesthetic and perform micro-suction, surgery is longer than when done under general anesthesia with larger instruments. However, recovery being much faster, the total downtime is very short [<3 days].


The degree of skin change after TLS is the same as expected if it were possible to lose an equal amount of fat in these localized areas simply by dieting.

This is because the thin cannula makes small tunnels to get the fat out whilst retaining the multiple connections between skin and muscle. These subsequently contract, aided by the vibration used, to result in skin retraction - without worry about excessive skin folds.

This effect is so dramatic that many patients requiring a “tummy tuck” can now have excellent results simply by having TLS which also removes fat at the same time.


In FT, the TLS harvested tissue is specially treated to obtain pure, sterile, concentrated fat for transfer to other body parts like sunken cheeks, facial ageing lines, depressed upper buttocks or vulva and breasts for their enlargement and shaping.

Revolutionary advances now make FT safe and effective. Usually, over 50% of the fat will survive in the long term to give a fuller and more flattering contour.

Synthetic fillers and silicon cannot match natural fat in terms of extent of filling and quality of results. They also carry foreign body risks and are expensive.


The few small incisions do not require stitches – and, together with good drainage of the oil and blood tinged anesthetic fluid, healing is rapid and dramatically improved.

You can return to light exercises within a few days, waiting a little if you feel significant soreness. To gain maximum benefit, graduate back to a good exercise regime soon.
