LASIK requires a thin slice of the cornea (corneal flap) for vision correction, so the incision is relatively large. SMILE is a new laser vision correction operation requiring only a small incision of 2-4 mm without uncovering the flap, so the incision area is reduced by nearly 80%. Postoperative dry eyes and infections are reduced, and recovery time is faster. Moreover, there will be no flap-related complications after the surgery.


However, there is a misconception that SMILE is a new technology and should be better than LASIK. In fact, it is necessary to choose the appropriate surgical method according to your personal situation. If you have, for instance, hyperopia or myopia above 1000 degrees, SMILE can not be your choice.

Most people are suitable for SMILE. Yet, a detailed eye examination by an ophthalmologist is required to confirm this, as some eye issues, such as cornea too thin, cone-shaped cornea, severe lack of tear secretion, may go undetected. You can attend a free SMILE seminar at Vivid Eye Centre where an ophthalmologist will give you a detailed explanation and preliminary eye examination and evaluation will be conducted.

  • Ocular development not yet complete
  • Refraction not yet stable
  • Cornea too thin/Keratoconus (requires corneal collagen cross-linking)
  • Too high the refractive errors
  • Hyperopia (Long-sightedness)
  • Known eye disease (e.g. cataract, glaucoma)
  • Infection of the eye
  • Corneal scarring or other corneal disease
  • 嚴重Dry Eye/嚴重缺乏淚水分泌
  • Patients with herpes
  • Immune system disorders (e.g. rheumatoid arthritis, lupus erythematosus)
  • Prolonged use of steroids
  • During pregnancy/lactation

It is advisable to seek treatment for dry eyes first and if necessary, consult an ophthalmologist for advice and treatment. We also welcome you to visit our Dry Eye Centre, where we offer analysis and treatment for mild to severe dry eye conditions. The Centre incorporates the latest diagnostic techniques to identify the root cause of dry eye and pioneers the use of the latest and most advanced treatment methods.

A comprehensive eye examination, including a prescription test, corneal thickness and curvature test, is required before the procedure can be carried out. Accurate data can be used to formulate an appropriate vision correction plan. Prior to the first eye check, the client will need to stop wearing contact lenses.


  • Soft contact lenses (ex astigmatism): off for at least 1 week
  • Soft contact lenses (including astigmatism): off for at least 2 weeks
  • Hard contact lenses: off for at least 1 month
  • Contact lenses for vision correction: off for at least 3 months

The first examination and the SMILE surgery can take place on the same day at the earliest.

The surgery will be performed under local anaesthesia in the eyes, so the patient will not feel much. The process can be completed within 10 minutes.

There is a chance of presbyopia as the small muscles that pull on the lens usually begin to degenerate after the age of 40, causing the near vision to become blurred. SMILE can also tackle the issue of presbyopia. For more information, please contact our ophthalmologists or attend a free SMILE seminar.

Mono Vision is a solution to presbyopia, where one eye is responsible for long-range vision and the other eye for near vision. For example, one eye is corrected to near-zero degree and the other eye is left with 100 to 200 degrees of myopia.

Many people think that the surgery is only successful when there is no refractive error, but this is a misconception. The success rate of vision correction is within +/- 75 degrees. 90% cases are now within +/- 50 degrees, which does not affect their daily lives. Enhancement can be performed if the patient beyond a certain level of refractive errors considers it is affecting his/her daily life.

Yes, SMILE procedure only changes the curvature of the cornea and does not affect other eye tissues.

Yes, but additional collagen cross-linking is required. It is suitable for people with unduly-high refractive errors or extra-thin corneas, or those suspected of having the risk of keratoconus. The ophthalmologist will assess the client prior to surgery to determine if additional corneal collagen cross-linking is required. The cross-linking is a treatment of applying riboflavin (a vitamin B2) eye drops to the patient's eyes over which UV light is then directed for 45 seconds to 1 minute, strengthening the corneas as the corneal collagen fibres cross-link.
