Laser Vision Correction

In general, laser vision correction may be considered for people who do not wish to use glasses or contact lenses for personal, occupational or medical reasons. These are: LASIK, ReLEx SMILE and Advanced Surface Ablation (PRK, LASEK, Epi-LASIK). Laser vision correction can treat Myopia, Hyperopia and Presbyopia or ‘Lao Hua’ when performed with monovision.

The requirements for laser vision correction are:

1. Minimum age of 18 years.

2. Stable myopia, hyperopia or astigmatism.

3. Absence of pre-existing eye conditions such as severe dry eyes, advanced glaucoma and keratoconus.

4. Absence of certain systemic conditions such as uncontrolled diabetes.

5. Regular corneal shape and thickness.

6. Not Pregnant

What is LASIK?

LASIK is a laser eye surgery procedure commonly used to treat myopia, hyperopia and astigmatism. The LASIK surgery procedure reshapes the cornea and focuses light into the retina, for better vision. LASIK surgery is painless and takes only about 15 minutes for both eyes. After the procedure, patients are usually able to see without glasses or contact lenses within a few hours. As vision stabilises over the next few days, vision continues to improve.

How is LASIK Performed?

LASIK surgery in Singapore is performed by creating a very thin, superficial flap in the cornea with a microkeratome or a femtosecond laser. Once the hinged flap is folded back, the surgeon can access the underlying cornea and remove some corneal tissue using an excimer laser. The excimer laser directs an ultraviolet light beam, reshaping the cornea so that light entering the eye focuses more accurately on the retina for improved vision. The flap is then laid back in place after the cornea has been reshaped with laser ablation. After LASIK surgery, the flap is sealed to the cornea beneath.

Benefits of Lasik Surgery

With the abundance of benefits LASIK surgery brings, it continues to rise in popularity, with more people undergoing the procedure. Firstly, LASIK surgery eliminates the need for contacts or glasses. For contact wearers, this offers a better cost-efficient solution in the long run. The cost of contacts can average to about $375 to $450 a year, rendering LASIK surgery cost in Singapore to be more worth the investment. For glasses wearers, LASIK surgery provides greater convenience, especially when it comes to sports related activities. Moreover, being able to wear shades and sunglasses are no longer a hassle.

Secondly, LASIK surgery has long-lasting results. Once the eye has stabilised for about three months, LASIK results are expected to be permanent. The recovery process of LASIK surgery is also quick and effortless. Majority of ophthalmologists estimate that patients can return to their normal schedule within a day or two of surgery, unless they work in particularly dirty or dusty conditions. Last but not least, LASIK surgery improves vision. In fact, 90% of patients performing LASIK get 20/20 vision or better!


ReLEx SMILE (Refractive Lenticule Extraction – Small Incision Lenticule Extraction) is a minimally invasive, flapless lenticule extraction procedure that is FDA-approved and ideal for those with active lifestyles. ReLEx SMILE in Singapore enables some of the benefits of LASIK to be achieved with less invasive surgery. By creating and removing a tiny piece of corneal tissue within the eye, ReLEx SMILE can reshape the cornea. In contrast to LASIK surgery, where a 22mm cut is made, the lenticule is extracted through a 2mm micro-incision, resulting in a faster and more comfortable healing process. No flap is created, which eradicates the risk of flap complications (dislodgement, wrinkles, inflammations) or dry eyes.

Ultimately, conditions vary from patient to patient. Should you plan to undergo eye surgery, it is highly recommended to consult your eye specialist. Your eye specialist will assess your eye condition and determine the most suitable treatment option, whether it be LASIK surgery or reLEx SMILE for you!

Laser Vision Correction
wide variety of refractive errors

Laser vision correction is able to treat a wide variety of refractive errors including myopia, hyperopia and astigmatism. Presbyopia or ‘lao hua’ may be helped with monovision techniques.

This was first approved by the FDA in 1998 and many millions of patients have had it performed. In general, satisfaction rates are well over 90% and sight threatening complications such as corneal ectasia and infection are very rare.
Lasik is a two-step process where a corneal flap is first created with a femto-second laser and then laser ablation performed under the flap with a second excimer laser. The flap is then carefully repositioned and vision typically recovers very quickly but is not immediate. There may be some irritation after surgery but patients are usually back to normal daily activities the next day. Sometimes, a protective bandage contact lens is used which is removed by the surgeon after 1-3 days. The whole treatment is performed under topical anaesthesia (eye drops) and takes about 12-15 minutes. Mostly, patients need 2 days off work. Medicated eye drops are prescribed for 1 week. Lubricating or medicated eye drops may sometimes be needed for dry eyes for a longer period on a case by case basis. Lasik is a safe and effective treatment for the correction of refractive errors and has been approved by both the SAF and US military.
