ReLEx® SMILE (Refractive Lenticule Extraction, Small Incision Lenticule Extraction) is a bladeless, gentle and flapless laser vision correction using only one femtosecond laser for the entire procedure.

ReLEx® SMILE, an alternative to LASIK, is able to correct shortsightedness, astigmatism (“san guang”) and is often suitable for patients with high myopia, dry eyes and contact lenses intolerance.

The entire ReLEx® SMILE procedure is performed with gentle, low suction such that vision is preserved with no “black out” phenomenon.

ReLEx® SMILE does not require the patient to change positions from one laser platform to the other, thus providing greater comfort and shorter time to complete the procedure. In a single step of less than 30 seconds, a low energy laser creates a tiny piece of refractive lenticule and a small pocket incision of less than 4mm on the cornea surface. This refractive lenticule is then removed by your eye surgeon through the small pocket incision. Removal of the refractive lenticule changes the shape of your cornea, thus correcting your refractive errors. Typically, visual recovery occurs in the first week following surgery and the eye may feel irritated for a day or so. There is usually minimal downtime after ReLEx® SMILE and patients are able to return to their daily activities after a day of rest.

ReLEx® SMILE, being a flapless procedure, has a shorter healing time. As no corneal flap is created, the upper corneal structure remains practically untouched. Therefore, the structural stability of the cornea will be largely unaffected. With no corneal flap being created, you will not have flap complications such as displacement or dislodgement. There will also be reduced post-surgery dry eye discomfort.

An ideal candidate for ReLEx® SMILE would be:

  • 18 years of age and above
  • Not pregnant
  • No significant past medical or eye history and no family history of eye disease
  • No significant change in spectacle prescription within the past 12 months
  • Myopia between 100 to 1000 degrees
  • Astigmatism of up to 500 degrees

ReLEx® SMILE aims to reduce your dependency on spectacles and contact lenses in order to improve your quality of life.

By choosing ReLEx® SMILE, you will be making complete and exclusive use of the high-precision ZEISS VisuMax® device – and enjoying the benefits of modern femtosecond technology.


To take your first step towards better vision

Make an appointment for a consultation and eye assessment with us to find out if you are a suitable candidate for ReLEx® SMILE. The comprehensive eye tests with our team of experienced optometrists will take about 2 to 3 hours. Some of the tests to be carried out include the measurement of your eye degree, eye pressure, corneal curvature, corneal thickness, dilation of your eyes and also to look out for any other eye abnormalities. Our ophthalmologists will discuss with you, your suitability for ReLEx® SMILE as well as the risks and benefits based on your eye assessment results.
