ReLEx® SMILE

small incision
lenticule
extraction

  • Only takes about 4-5 minutes
  • Up to 80 % smaller side-cut
  • Odorless procedure
  • Close to 100% patients achieve 20/20 vision after surgery
  • Majority of upper corneal layers remains intact
  • Low incidence of transient dry eye syndrome
What is ReLEx® SMILE?

ReLEx®SMILE is the most advanced laser eye surgery technique that can be used to treat short sighted patients. It is the third generation keyhole surgery that uses laser pulses to reshape cornea and correct short sightedness. ReLEx® SMILE is exclusively performed with the femtosecond laser system VisuMax® from ZEISS.

Advantages of SMILE Myopia Correction
Small incision of 2 – 4 mm
Fast treatment
Quick recovery
Up to 80 % smaller side-cut
No burning smell during procedure
Low risk of complications
Stability of the cornea
ReLEx® SMILE Procedure
  • Step 1: A refractive lenticule and small incision of less than 4 mm are created inside the intact cornea – all in one step.

  • Step 2: The lenticule is removed through the incision with only minimal disruption to the corneal biomechanics.

  • Step 3: The removal of the lenticule changes the shape of the cornea, thereby achieving the desired refractive correction.

Advantages of ReLEx® SMILE

LASIK involves cutting a flap and folding it back to remove corneal tissue point by point. ZEISS ReLEx® SMILE, on the other hand, makes minimally invasive, flapless refractive correction possible for the first time. Utilizing the highly precise ZEISS VisuMax® femtosecond laser, it performs the vision correction in a single treatment process. Since the lenticule and access incision are created together, there is no need to reserve a margin of tolerance, and the cornea remains largely untouched.

Frequently Asked Questions About ReLEx® SMILE
  • Any dry eye issues after ReLEx® SMILE surgery?

    As the number of corneal nerves affected during the procedure is far lower than that in LASIK, the resulting dry eye symptoms are significantly lesser or near zero in patients undergoing ReLEx® SMILE.

  • Can I receive other eye operations after SMILE? (Such as: cataract surgery)

    Yes, you can. SMILE surgery will only change the shape of the cornea. Other tissues in the eye are not affected. Therefore, you can receive other eye operations after SMILE.

  • Can I wear cosmetic contact lenses and eye makeup after laser?

    You can start wearing eye makeup and do beauty parlor treatments after 15 days, and after having checked with our doctor on your post treatment visit. Cosmetic contact lenses can be worn after consultation with your surgeon, but are usually allowed a month later.

  • Will I be able to see clearly immediately after the treatment?

    As a rule, one day after the procedure you will be able to see 80-90% of what you were able to see with your glasses/contacts before treatment and within 3 days you should have perfect vision.

  • Is it necessary to attend a hospital?

    No. Modern refractive surgery is fast and safe; and no anesthesia (apart from anesthetic eyedrops) is required. Therefore, there is no need to be admitted to a hospital.

  • How much time do I need to take off from work after the surgery?

    It depends on your job nature. You are advised to rest for 1 to 2 days after the surgery. Many patients can go back to work in 2-3 days following SMILE surgery. Air travel would not be affected after SMILE.

  • Who is not suitable for laser eye surgery?

    · The refractive error is not stable in the past year
    · The cornea is too thin
    · Suffering from keratoconus
    · Suffering from cataracts or glaucoma
    · Immune system problems, such as rheumatoid arthritis, lupus etc.
    · Pregnant or lactating woman

  • Does LASIK or SMILE surgery reduce the risk of developing cataracts, retinal detachment and glaucoma at a later date?

    In refractive surgery, we modify the corneal curvature in order to eliminate the need of spectacles. The underlying shape of other parts of the eye (eg. retina) are not changed. Thus, the risk of developing other ocular conditions such as cataract remains the same. Patients with high myopia (more than 6 diopters) before refractive surgery are advised to undergo regular ophthalmic check-up since they are at risk of developing these conditions.
