SMILE Laser Vision Correction

SMILE laser vision correction surgery is a revolutionary technique for correcting myopia with multiple advantages. SMILE corrects vision by using a laser to cut a middle layer of corneal tissue (called a lenticule), thereby reshaping the corneal curvature. Compared to traditional LASIK, SMILE requires only a small incision of about 2-4mm. This smaller incision not only reduces surgical risk and shortens recovery time but also preserves more of the intact corneal tissue, minimizing the potential structural risks to the cornea and reducing the risk of postoperative dry eye.

Comparison of SMILE/SMILE®pro and ICL Vision Correction

Process of SMILE Vision Correction

1. Using a femtosecond laser to directly cut the middle layer of the cornea.

2. Creating a small incision of approximately 2-4mm.

3. Extracting the cut corneal lenticule through the incision.

Candidates Suitable for SMILE

  1. Myopia less than 1,000 degrees and astigmatism less than 500 degrees
  2. Age between 18-45 years old
  3. Fully developed eyes with stable myopia
  4. Normal corneal thickness

Pre-Examination and Vision Correction Precautions

  1. Stop wearing contact lenses 7 days prior to the examination and surgery
  2. Wash your hair the day before or on the day of the vision correction procedure, and try to avoid washing your hair that same night
  3. You may bring sunglasses on the day of the vision correction procedure if needed
  4. Avoid wearing tight, high-neck, or pullover clothing on the day of the vision correction procedure
  5. The pre-surgery examination will take about 2 hours, so please allocate sufficient time to stay at the clinic
  6. Avoid wearing makeup, perfume, or volatile products on the day of the vision correction procedure
  7. It is recommended to have a friend or family member accompany you when leaving
  8. Avoid driving on the day of the vision correction procedure

  1. What Are the Differences Between SMILE and SMILE®pro?
    The surgical principles of SMILE and SMILE®pro are the same, but SMILE®pro has a faster laser frequency. The laser procedure for one eye takes only 10 seconds, compared to the 23 seconds required for the previous generation SMILE, more than doubling the speed. This significantly reduces patient anxiety and discomfort. Additionally, SMILE®pro has upgraded laser positioning with visual axis and astigmatic axis navigation assistance, reducing the time needed for manual positioning by the doctor, making the surgery more accurate and smoother.
  2. What Are the Differences Between SMILE/SMILE®pro and LASIK?
    Both SMILE/SMILE®pro and LASIK laser vision correction involve reshaping/removing corneal tissue with a laser to change the curvature of the cornea and correct vision. LASIK requires an initial laser cut to create a corneal flap before reshaping the middle layer of the cornea. In contrast, SMILE/SMILE®pro directly cuts the middle layer of the cornea with a laser and then removes it. By eliminating the step of creating a corneal flap, SMILE/SMILE®pro significantly reduces the wound area by 80%, leading to better wound healing and faster recovery.
  3. What Is Enhancement Surgery?
    If there is a degree of regression after vision correction surgery, we can perform enhancement surgery based on the situation. However, this is not common.
  4. Is SMILE/SMILE®pro 100% Effective in Curing Myopia?
    Many patients believe that vision correction will result in zero myopia and even better vision than wearing glasses or contact lenses. This is a misconception.

    Vision Correction Success Standards:
    Achieving the pre-determined target degree within ±75 degrees is considered successful ; Less than ±75 degrees is considered normal vision.

    According to literature, the success rate of achieving within ±100 degrees three months after vision correction is nearly 100%;
    With approximately 97% within ±50 degrees
    If the degree exceeds ±100 degrees after vision correction, an enhancement procedure can be performed to improve it.
  5. How Long Does It Take for the Fog to Clear After SMILE/SMILE®pro?
    The situation varies from person to person. Generally, the fog will clear within two weeks to one month after vision correction.
  6. Are There Surgical Risks with SMILE/SMILE®pro?
    All surgeries carry risks, but the risks associated with SMILE/SMILE®pro vision correction surgery are relatively low. Common conditions include:

    Reduced night vision
    Seeing ghost images, glare
    Dry eyes

    Most of these conditions can be improved with treatment and generally do not cause long-term effects. If necessary, please consult your doctor. However, vision correction cannot change complications caused by myopia, such as retinal detachment, glaucoma, and macular hemorrhage.
