Many people think that zero myopia or astigmatism will be achieved after vision correction, or the vision will be even clearer vision than wearing glasses or contact lenses, but this is a wrong concept.
Successful criteria for vision correction: If the outcome is within +/- 75 degrees of the target, this is a successful outcome. When the refraction is less than +/- 75 degrees, the vision is usually within the normal range.
According to evidence, a refraction of +/- 100 degrees at 3 months after surgery is seen in nearly 100%; if over +/- 100 degrees is noted after surgery, enhancement treatment would be an option.

Ophthalmologists suggest that it’s better to undergo SMILE with at least 6 months of stable refraction. Generally, a smaller incision is made during SMILE, and the structure of the cornea remains more stable with lower chances of fluctuation postoperatively. Please consult your ophthalmologist as early as possible if you have a sudden visual change that might be caused by other issues.

Our clinic suggests that since we need at least 2 days to conduct comprehensive eye examinations so that we can obtain correct data and design a personalized vision correction plan for you, please make your appointment early. Please stop wearing contact lenses before eye checkup:
Soft contact lenses (excluding astigmatism): Stop wearing them for at least one week
Soft contact lenses (including astigmatism): Stop wearing them for at least two weeks
Rigid contact lenses: Stop wearing them for at least one month
Ortho-K lenses: Stop wearing them for at least three months
*after the first eye check-up, the pre-operation examination and vision correction could be conducted on the same following day.

SMILE is an advanced laser correction technology that improves the limitations of LASIK. For example, LASIK requires the creation of a corneal flap, so the incision is larger than SMILE. SMILE only has a small incision of 2-4mm, without creating a corneal flap, so the incision area is reduced by nearly 80% as compared to LASIK. Therefore, it lowers the chances of getting dry eye, infection, and corneal flap displacement. At the same time, recovery time is shortened.

Anesthetic eye drops are placed into your eye to numb the eyeball, so there is usually no pain experienced during the procedure. The surgery in both eyes is usually completed in less than 15 minutes.

Usually, the procedure itself only takes about 15 minutes. However, you will need to stay for around 2 hours for pre-operative preparations and examinations on the day of surgery.

More than 2 million successful SMILE surgeries have been done worldwide. It is an advanced technology from Zeiss in Germany. It was approved by the European Union in 2011 and approved by the US FDA in 2016. The clinical results of the FDA data found that SMILE is safe, stable, and highly effective. Meanwhile, 88% of guests had unaided eyesight above 1.0 at 6 months after surgery.

Presbyopia happens when the crystalline lens hardens and loses its elasticity at the age around 40-50. It is an unavoidable age-related condition and has nothing to do with SMILE.

People who：
-have unstable refraction
-have thin cornea, or severely nearsighted / farsighted
-are suffering from severe dry eye
-have a history of glaucoma or retinal problems
-have infection on cornea, such as inflammation or previous trauma
-have immune system disease, such as rheumatoid arthritis or lupus
-are in need of long-term steroid intake
-are pregnant

SMILE is a minimally invasive technology, which does not require general anesthesia. Only anesthetic eye drops are placed into your eye and you don’t need to stay after surgery. Our clinic is equipped with aseptic operation rooms with surgical instruments and advanced examination machines that meet international standards. The whole process is safe and reliable.

Risks come with all surgeries and they are relatively low with vision correction. The common risks are under-correction or over-correction, night vision worsens, dry eyes, halos, and dry eyes, etc. Complications after vision correction are uncommon. Under rare circumstances, complications like corneal infection or bacterial infection may occur.

According to a survey from the Journal of Cataract and Refractive Surgery in 2016, ophthalmologists were nearly 5 times more likely to receive vision correction than the general public. Many ophthalmologists chose to get rid of glasses by getting vision correction done.

Yes. SMILE only changes the curvature of your cornea and other parts of the eyes are not involved and will not be affected.

SMILE Xtra is a type of corneal cross-linking surgery. It is suitable for patients: whose cornea is too thin, who have severe myopia, hyperopia, and astigmatism, or who are suspected of being at risk of keratoconus. Your surgeon will evaluate your conditions and decide if you need Xtra cross-linking surgery together with your vision correction surgery or not. Usually, riboflavin eye drops will be applied to your eyes and your eyes will be exposed to UVA light to strengthen your cornea. Cross-linking surgery can be simultaneously completed with SMILE.

It usually takes 20 minutes for both eyes. However, we suggest you stay for 2-3 hours for pre-operative preparations and examinations.

No, anesthetic eye drops are placed into your eye and an instrument will be used to prevent the lids from blinking. Your doctor will guide you through the process with clear instructions.

Basically yes. However, we suggest that it is better to sleep for 4-6 hours or take one day off after surgery. A supine position is highly recommended, our clinic will provide you with an eye shield to protect your cornea during your sleep.

Basically yes. Eyes undergone laser surgery will not be affected by air pressure; therefore, it is OK to get on the plane. However, we highly suggest a follow-up visit the next day after surgery to make sure everything is OK.

We do not recommend washing your hair the same day after surgery to avoid non-sterile water from getting into your eyes. If non-sterile water does get into your eyes, please use the eye drops we prescribed and contact us as early as possible.

No, you can have your normal diet.

Theoretically, there is no conflict between squint surgery and LASIK. However, we recommend patients under 18 years old to wear glasses to improve their squint. For squint patients over 18 years old, please consult your ophthalmologist before any surgical plan. For patients with accommodative squint, it’s an option to get vision correction surgery first and then get your squint corrected later if you do not want to wear glasses. For patients with other types of squint, since the squint itself might have already impacted your quality of life and getting vision correction surgery will not benefit your squint situation, therefore we don’t recommend you to have vision correction.
