FAQ

Most people are suitable for doing laser surgery.
With the progress of laser technology, laser fixation can fix more and more extensive visual problems, even if deeper myopia, astigmatism, presbyopia and other visual problems are likely to be improved. However, a detailed examination conducted by ophthalmologist is needed to determine whether you are suitable for laser fixation or not. We welcome you to participate in our talk. Ophthalmologist will hold the talk and a preliminary preoperative assessment will be performed for the participants.

It is a wrong idea that many people will think that they can restore zero degree of myopia after laser surgery.
Successful criteria of laser:
It is successful if it can reach +/- 75 degrees of the target degree. Less than +/- 75 degrees are considered as normal vision.
According to recent survey, after 3 months of correction, the success rate of having myopia within +/- 100 degrees close to 100%;
97% of which is about +/- 50 degrees
If the degree of myopia is over +/- 100 degrees after 3 months of correction, an enhance surgery could be conducted to make improvement.

In general, inapplicable people include:

whose cornea is too thin & the degree of myopia is too high

who has not enough tear secretion

who suffers from eye disease such as glaucoma or retinal disease

who has incomplete eye development with unstable myopia

whose cornea has an infection, such as inflammation or injury

who suffers from autoimmune diseases, such as rheumatoid arthritis or lupus erythematosus

who has long-term use of steroids

who is pregnant or breastfeeding

All surgery is risky, relatively speaking, the risk of vision correction is lower. The general situation is:

Inadequate correction / excessive correction

The ability of night vision is reduced

Having ghosts shadow and glare when seeing

Dry eye

However, vision correction cannot change the complications caused by myopia, such as retinal detachment, glaucoma and macular bleeding. Most of the above can be improved through treatment, generally do not constitute a long-term impact. If necessary, please contact your doctor.

In fact, ReLEx SMILE has 6-year of history, recognized by European Union in 2011, and globally launched for nearly 50 million cases.
At the same time, the US Food and Drug Administration (FDA) has approved VisuMax femtosecond laser for SMILE in 2016, and the FDA clinical results show that SMILE is with high-level of safety and effectiveness.There are 88% of patients’ visual acuity is 1.0 or more after 6 months of doing ReLEx SMILE.This data is higher than the clinical outcome of other laser surgeries performed by the FDA.

Before SMILE surgery, the doctor will measure the curvature of corneal of the patient, conduct detailed eye examination and make assessment to ensure that patient is suitable for doing SMILE surgery. Our ophthalmologists are experienced and will regularly hold seminar with SMILE experts to exchange professional ideas all over the world; work with German company Zeiss in the field of scientific research and ophthalmologic technology, provide patients with safety.

Before SMILE surgery, the doctor will measure the corneal curvature of the patient, conduct detailed eye examination and evaluation to ensure they are suitable for SMILE surgery. Therefore, sequelae are not a common case.

Theoretically, everyone will have presbyopia sooner or later. Doing LASIK/ SMILE does not affect the time of appearing presbyopia. There are even some cases that people with presbyopia can postpone the need of wearing presbyopia glasses.

No. Presbyopia is the natural degradation of crystalline lens, which means the crystalline lens are losing elasticity so that people cannot focus on the scene in a close distance. However, the theory of Lasik / Smile is to change the curvature of the corneal to achieve the effect of vision correction, there is no negative effect will have caused to the crystalline lens.

SMILE technique has been studied for more than 20 years. The technique is greatly improved over the years. Also, stricter selecting process of SMILE patients will lower the risk of the surgery. Only suitable patients will be recommended. There are more than 700,000 SMILE cases have been completed and no blindness has been caused.

Yes, you can. SMILE surgery will only make effect on eye cornea and will not affect other eye tissues. Therefore, you can receive other eye operations after SMILE.

No need. There is no relationship between eating and laser surgery.

Not necessarily. No hospitalization is needed for laser surgery. In addition, many vision correction centers, such as clarity SMILE LASIK Centre, are equipped with advanced surgical Instruments, operating room and other supporting equipment with international standards. Customers can have vision correction in an ophthalmology specialist Centre instead of a hospital, without having to coexist with “other patients” to lower the risk of bacterial infection.

Not everyone is suitable for laser surgery, for example, those whose cornea is too thin. In fact, many ophthalmologists and optometrists have done LASIK or SMILE.

Yes, it is possible. You can choose to conduct a detailed preoperative examination in the morning before doing laser fixation. Generally, two to three hours after preoperative examination can receive laser fixation.

On the day of laser surgery, we will arrange patient to take a rest in a comfortable room, in order to allow patient to relax and we will answer any questions about laser surgery. The procedure of laser surgery is very fast, just in about 15 minutes. Then, the patient will take a rest after surgery and see the doctor again. The whole process takes about 60 minutes.

No, it will not. The doctor will local anesthesia of patients’ eyes, and use the instrument to fix the eyes. The patient can be peace of mind to receive correction with the care of the medical team.

Rehabilitation time of laser surgery is mostly less than 24 hours. On the day after surgery, you can work as normal. The only limitation is to avoid excessive vigorous exercise and rub the eyes within a week after surgery. Clarity SMILE LASIK Centre will make appropriate recommendations based on your occupation and lifestyle.

In the early stages after presbyopia correction, the patient may take time to adapt and focus when reading in insufficient light condition and driving. Most people do not need to rely on presbyopia glasses in daily life. A week later, it will be okay to do sports, swim and do other exercises.

The doctor will provide professional advice on a case-by-case basis.Clarity SMILE KASIK Centre provides you with a free enhance surgery within 5years after receiving laser surgery.

Doctors recommend that you do not wash your hair on the day of receiving laser surgery. If there is sewage flow into the eye, you can use the doctor’s eye drops and contact us as soon as possible.

No matter if you have received laser surgery or not, no direct contact with eyes and water or tap water is recommended. Unlike artificial tears, the salt content of the water will stimulate and hurt the eyes. Therefore, we recommend using artificial tears to relieve eye discomfort. After receiving laser surgery (about 3-6 months), the cornea will in the automatic healing process, the corneal nerve will be reborn. Therefore, the patient will be particularly sensitive to clear water, tap water, smoke, and dust. There may be tingling feeling. After the cornea is completely healed, the allergic reaction will be disappeared.

Theoretically, you can. The eyes would not be affected by air pressure after receiving SMILE surgery. Therefore, it is possible to take the plane. However, doctors will generally advise patients to be reviewed once a day after surgery to ensure safety.

Yes, you can. However, since the eyes will be more tired after surgery, doctors will suggest taking more rest.

As the curvature of the cornea will be changed after SMILE, wearing contact lenses may feel uncomfortable. If you feel discomfort, you should try to avoid wearing. It is recommended to wear big eye colored contact lens a month after receiving SMILE surgery.

Cannot. In order to avoid inflammation caused by chemicals, the doctors recommend patients to stop wearing eye makeup for 3 – 5 days.

Before letting patients receive vision correction, we perform detailed and rigorous pre-screening examinations, including visual acuity, tear review, pupil size measurement, measurement of corneal thickness and corneal topography for each patient. We will measure wavefront aberration and iris Identification, and conduct eye health checks including glaucoma, retinal examination, etc., to ensure that patients are suitable for vision correction.
