Most Frequently Asked Questions

How long does the treatment remain effective?

In most cases, the correction remains stable over time. Rarely, the patient may experience a regression; in this case they will be offered a follow-up procedure.

Can you lose your sight as a result of this surgery?

Refractive surgery is a tried-and-tested technology that comes with very little risk. Loss of vision after refractive surgery is extremely rare, and usually results from an infection.

Are both eyes treated at the same time?

Yes, both eyes are usually treated during the same procedure in the case of laser surgery. However, in the case of intraocular surgery we will leave an interval of a few days between operating on each eye in order to facilitate recovery.

I'm afraid of having an operation. What will happen if I get stressed and move?

Refractive surgery is not a painful procedure. You will not experience any unpleasant sensations or pain during the procedure. If needed, you will be offered a relaxant half an hour before surgery to help put you at ease. Moreover, the laser is equipped with a system for monitoring the position of the eyes, which effectively compensates for any involuntary movement on the part of the patient.

Is it true that any kind of refractive surgery should be avoided prior to pregnancy?

Absolutely not. It is true that your vision may fluctuate during pregnancy (or breast-feeding). However, pregnancy does not cause permanent changes in visual defects.

Myopia

Is myopia hereditary?

Yes, it is true that your risk of developing myopia is higher if one of your parents also suffers from it.

Can refractive surgery correct myopia?

Certainly. Myopia can be corrected using refractive surgery. Our latest-generation lasers allow us to correct myopia of up to -10.0 dioptres in record time.

Is it possible for myopia to go away on its own?

No, unfortunately it is not possible for myopia to improve of its own accord. In fact, this visual defect tends to get worse as a person gets older, before stabilising at the age of around 25 on average. Slight fluctuations can also be seen during certain periods of a person’s life, such as during pregnancy or a growth spurt.

Hyperopia

Is hyperopia progressive?

No, it is not progressive. It only becomes a problem later on, when the eye starts struggling to focus. Often, it is only when they begin suffering from presbyopia that people notice they are also hyperopic. It should be noted that a person with severe hyperopia will also notice an impairment of their distance vision.

Is there surgery available to correct hyperopia?

Yes, there is. Laser surgery to correct hyperopia involves reshaping the cornea to make it more curved, so that the image of an object forms on the retina itself (focal point). The most frequently used technique for operating on hyperopia is femto-LASIK.

Is hyperopia hereditary?

Like myopia, hyperopia has a hereditary factor. However, it may also be linked to other diseases that will have to be investigated.

Astigmatism

Is there surgery available to correct astigmatism?

Yes. Astigmatism correction is commonplace in refractive surgery, as this defect is sometimes isolated but is more often associated with myopia or hyperopia. Contrary to popular belief, astigmatism is operable whether isolated or associated with another optical defect.

Is astigmatism hereditary?

Astigmatism is usually genetic. This means that it is present from birth and remains relatively stable over a person’s lifetime. It is also possible to develop astigmatism later in life, for example following a surgical procedure (cataract surgery, corneal graft) or as a result of an infection, herpes virus or certain other diseases.

Is astigmatism progressive?

No. In the absence of other pathologies, astigmatism does not generally progress over time, unlike myopia and hyperopia. That is why it is important to consult an ophthalmologist in order to rule out the possibility of keratoconus when children or young adults experience a sudden deterioration in their astigmatism.

Presbyopia

When does presbyopia start developing?

All people start showing signs of presbyopia around the age of 40–45, which is when the performance of our lenses starts to decline. Our focussing power diminishes due to a loss of elasticity caused by the ageing process. However, presbyopia does stabilise after the age of 60.

Is presbyopia preventable?

No. This vision problem is a result of the natural ageing of the lens. As such, we cannot prevent or slow down presbyopia; we can only correct it.

At what point is it possible to operate to correct presbyopia?

Operations to correct presbyopia are intended both for individuals above the age of 40 who are having difficulty reading and for those with more advanced presbyopia who are unable to read at all without glasses. The procedure allows the patient to forgo glasses entirely, or at least to only need them on rare occasions.

The SMILE technique 

What visual defects can be treated using the SMILE technique?

Currently, it can only be used to treat myopia and astigmatism. Studies are ongoing into using the technique to correct other visual defects.

Can I do sport after undergoing SMILE treatment?

With SMILE treatment, all activities can be resumed as normal 48 hours after the procedure with the exception of water-based activities (such as using a swimming pool, sauna, steam room or jacuzzi, or swimming in a lake etc.), which must be avoided until 7 days after the surgery.

Can you rub your eyes when you have had SMILE surgery?

Yes, you can rub your eyes from the day after the procedure.

The Femto-LASIK technique

Can I wear make-up after the operation?

Make-up presents a risk of infections and corneal injury, which is why it is strongly recommended to refrain from using make-up, especially around the eyes, for one week.

How long do I have to wait before I can drive again?

After femto-LASIK refractive surgery, you can drive again from the following day. However, caution is advised when driving at night, as halos may appear that can disrupt your vision.

Can I do sport after undergoing femto-LASIK surgery?

Caution is advised when doing sport. You must wait 1 month before doing contact sports such as karate, judo, handball, basketball, football, swimming and other water activities, etc. You can start jogging or going to the gym again after 7 days.

The PKR technique 

Do both eyes have to be operated on in one day?

That depends on the technique and on the surgeon. When using traditional PRK, it is generally preferable to wait 1 month before operating on the second eye. However, in the case of transepithelial PRK, both eyes can be operated on in the same day.

Is the operation painful?

During the procedure, anaesthetic drops are placed in the eye in order to numb the surface of the cornea for the entire duration of the operation. After the procedure, PRK patients may experience some pain for the next 24 to 48 hours. This pain seems to be less severe after transepithelial PRK.

Will I be eligible for sick leave from work?

Yes, you will be given a medical certificate granting you 5 days of sick leave. However, depending on the nature of your work and how comfortable you are, this period can be extended by several days.

The LBV technique 

Can my presbyopia and myopia be corrected at the same time?

Yes, it is possible to treat myopia at the same time as presbyopia. Presbyopia can also be treated at the same time as other refractive errors (myopia, hyperopia, astigmatism).

What is the objective of LBV treatment?

The objective of LBV treatment is to allow you to see without glasses, both long-distance and close-up.

The ICL technique

How long does the surgery take?

The operation takes 45 minutes per eye. This time includes preparation and fitting of the implant.

Do both eyes have to be operated on in one day?

No. For this type of surgery, both eyes will only be operated on in the same day under exceptional circumstances. It is recommended to leave a few days in between operating on each eye.
