Refractive surgery
PRK (refractive photokeratectomy)
Prior to eye surgery
ABERROMETER
The aberrometer performs high-resolution wavefront measurements of both higher and lower-order optical aberrations before a topo-guided surgery, prior to a Femto LASIK or a PRK procedure.

BIOMETER
Used for the calculation of intraocular implants:
– prior to a cataract surgery
– for "Premium" refractive surgery:
* multifocal implants
* EDOF (Extended Depth of Focus) implants
* ICL (Implantable Contact Lens for high myopia)

CORNEAL TOPOGRAPHY
Enables a detailed analysis of the cornea and the detection of keratoconus.
Advantages of laser surgery
- Becoming independent from glasses and lenses
- Increase visual acuity and quality of vision by treating small optical defects that cannot be corrected with conventional glasses, by treating the patient's optical aberrometries by performing a tailor-made treatment guided by the topography of the cornea.
- Contact lens intolerance or history of keratitis
- Correct certain diseases of the surface of the cornea (hereditary dystrophy responsible for recurrent keratitis, Cogan's disease, etc.)
- Avoid the risk of infection associated with regular contact lens wear. (NB: a contact lens wearer has a much higher risk of developing an eye infection than with a single laser procedure, which guides the decision when it is possible to carry out permanent laser treatment)
- Easier practice of certain sports: swimming, mountain biking, jogging, etc.
- Make significant savings in the long term because you no longer need to regularly change glasses or lenses
- Professional indications requiring good vision without glasses (selection criteria for the navy, police, etc.)
How to know if I am a candidate for LASIK?
Step 1: Contact us if you decide that you now want to permanently say goodbye to your glasses and contact lenses.
We will schedule an appointment for a preoperative clinical evaluation.
You can also do so on our website: under the "Schedule an Appointment" tab / "Ophthalmologist" / "Laser Assessment."
Soit par mail : in**@*********bw.be
For any questions or if you can't find a suitable appointment, you can directly reach the laser secretary at 010/ 56 00 02.
tep 2: Preoperative Clinical Evaluation
You should plan for 1 hour on-site.
You will be examined, and a complete assessment will be carried out beforehand: vision check, intraocular pressure measurement, retina examination, topography, and pupillometry.


We will administer eye drops to dilate your pupils. Please note that this may affect your ability to drive on the way back. We recommend being accompanied.
At the end of the assessment, Dr. Sion will determine if you are a suitable candidate and will guide you toward the technique that best suits you. He will explain everything you need to know to make a clear decision.
All your questions are important and will be answered.
The use of soft contact lenses should be stopped at least 48 hours in advance, preferably, and rigid lenses for about 2 weeks.
The basic requirements for laser vision correction include:
1. You would like to stop depending on glasses and contact lenses and enjoy the freedom that this brings.
2. Your prescription is between -1 and -10 diopters (myopia), or up to +5 diopters (hyperopia), with or without a cylinder up to 4 diopters (astigmatism).
3. You are between 20 and 50 years old.
4. You rely on glasses or contact lenses for distance vision.
5. you have stable vision. (If you have your old glasses prescriptions, it is preferable to bring them with you.)
6. you do not suffer from any eye disease and have good vision in both eyes with your glasses.
7. You are in good general health.
Note: Laser vision correction can also help patients who need glasses for both reading and distance vision, but it is not intended for those who have good distance vision and only need glasses for reading.
Step 3: Laser Treatment Day
The treatments are performed at the Clinique du Parc in Maubeuge and at the Centre Médical Alliance in Braine L’Alleud.
Please present yourself at the reception. You will be re-examined to confirm your prescription and undergo further diagnostic evaluations, followed by the administration of anesthetic eye drops.
You will be in the laser room with Dr. Sion for about 10 to 15 minutes, while the laser treatment itself takes about 3 to 30 seconds, depending on the correction needed.
Dr. Sion will provide you with useful information about the application of eye drops.
Overall, you will be on site for about 1 to 2 hours.

Stage 4: Follow-up
All the pre-operative examinations and the operation take place at the Clinique du Parc, with follow-up in Jodoigne.
Patients who have undergone Lasik surgery should be seen again the following day.
PRK patients are generally seen 3 to 5 days after the operation to remove the contact lens.
Most patients who undergo Lasik surgery are able to resume their activities the next day.
Most PRK patients can usually return to work after about 5 days with good functional vision.
In the studies, the final maximum vision was identical at 3 months for both techniques.
Some post-operative restrictions:
It's important not to rub your eyes or let water get into them for the first week.
There are no restrictions on reading, using the computer, leaving the house or playing sport. Your eyes may be more sensitive than usual, particularly in the sun or in a smoky atmosphere.
Sunglasses should be worn outdoors depending on the amount of sunlight, especially after a PRK.
Make-up should be avoided for the first week and care should be taken not to rub the eyes when removing make-up.
Swimming and opening your eyes underwater should be avoided for 3 weeks.
Step 5: Make the most of years of glasses-free vision
Post-Laser Vision Correction Care
You will need to be accompanied by car after the laser procedure.
Eye drops should be started as soon as you return home.
After LASIK surgery:
- The hulls should be kept for 7 nights.
- A sensation of grains of sand is common, with watery eyes.
- Above all, don't hesitate to keep your eyes well hydrated with prescribed artificial tears (plenty of them, even 6 to 10 times a day if it makes you feel better).
- Visual autonomy returns the next day.
- Healing continues for the first month.
After a PRK operation :
- A soft lens (conventional, without correction) is fitted after the operation. The aim is to improve healing and prevent excessive eye pain (bandage effect). This lens should be removed between the 3rd and 4th day after the operation.
- Intense pain and photophobia are common in the first 2 days.
- Painkillers are prescribed and must be taken immediately to help control the discomfort and pain.
- Allow for 3 to 5 daysof social downtime (no computer use or driving).
- Visual autonomy is slower than with LASIK, taking 5 to 7 days.
- Healing continues for the first 3 months.
Note: At 3 months post-laser, neither technique (LASIK or PRK) has shown superiority in visual outcomes.
Fees for refractive laser treatment
Prices are around €900 to €1,500 per eye, depending on the technique and equipment used.
