How to know if I am a candidate for LASIK?

Anthony SION La chirurgie réfractive, Questions fréquentes

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**@op*********.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.

Aberrometer, for a unique, personalized treatment for each patient.

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

Anthony SION La chirurgie réfractive, Les conseils de votre ophtalmologue

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.

AMO's WAVE SCAN Aberrometer

Anthony SION Plateforme 100% laser

AN ADVANCED WAVEFRONT SYSTEM

Pushing back the limits of laser vision correction surgery, the iLASIK procedure offers an unprecedented level of precision and accuracy..

The procedure uses a combination of bladeless flap creation and Wavefront LASIK technology to ensure safer and more accurate results for our patients.

More accurate measurements:

The advanced wavefront system provides high-resolution data that enables the treatment of higher and lower order aberrations with extremely high success rates, offering a potentially superior vision correction alternative to glasses and contact lenses for candidates eligible for laser vision correction.

Excellent results:

The results of multicentre clinical studies show that the iLASIK procedure delivers excellent results.

For mild to moderate myopia: in clinical studies, 100% of patients treated for moderate myopia were able to pass a driving test without glasses or contact lenses, and 98% had 20/20 vision at best one year after treatment.

In the case of hyperopia, four times as many participants were very satisfied with their vision after the operation, compared with their vision before the operation with glasses and contact lenses.

For high myopia: only 2.2% of the eyes in the high myopia clinical trial had to be reprocessed.

Night vision was clearer: for all indications submitted to the FDA, satisfaction with night vision improved after the Wavefront LASIK procedure.

Ziemer's LDC Crystal LINE FEMTOSECOND laser (made in Switzerland)

Anthony SION Plateforme 100% laser

This laser-only operation is known as femto-LASIK.

Ziemer's LDV Crystal Line laser (Made in Switzerland) is a femtosecond laser that can produce a fine corneal flap of 110 microns using calibrated energy at ultra-precise points on the cornea (micron scale).

This laser avoids the (rare) complications that can occur in certain centres that still use a mechanical microkeratome.

The VISX STAR S4 IR excimer laser from AMO Johnson & Johnson

Anthony SION Plateforme 100% laser

The Excimer STAR S4 IR laser is designed to provide a lifetime vision correction through a laser treatment tailored to each patient, based on their individual aberrometric measurements.

This laser enables LASIK eye surgery specialists to perform the Wavefront LASIK procedure quickly and efficiently, while maximizing patient safety.

Advantages:

  • Offers the advantages of Iris Registration (IR: iris registration).
  • Preserves tissues by optimizing the ablation during treatment.
  • Eliminates the need for dilation; measurements are taken on a natural pupil.
  • Adjusts to the patient's eye movement (XYZ) with Eye Tracker to further improve the treatment accuracy of the WaveScan STAR S4 infrared laser system. Optimal results require precise alignment of the laser treatment.
  • By assembling the wavefront diagnostic information with the treatment itself during the iLASIK procedure, iris registration provides a much higher level of alignment accuracy, giving the surgeon confidence that the treatment will be placed in the right place.

Cataract

Anthony SION Troubles non réfractifs
Cataracte

Cataracts correspond to the opacification of the crystalline lens (a normally translucent, high-power lens located inside the eye). Every year, 570,000 people are operated on in France. Surgery is the only way to improve vision altered by cataract.

There are no alternatives to cataract surgery.

Because neither eye drops nor lasers can cure an established cataract. In very advanced cases, cataract can cause blindness.

Worldwide, it is the leading cause of blindness due to the impossibility of large-scale treatment in third world countries. Tens of millions of people are waiting to be operated on, but unfortunately, due to a lack of human and financial resources, many of them will no longer be able to see because of their cataracts. For this reason, many humanitarian trips are organised, particularly to Africa.

Intervention is defined when the opacification of the lens is sufficiently significant, vision deteriorates slowly, often in distance vision with sometimes paradoxically a transient improvement in near vision without glasses.


The degree of discomfort is not the same for everyone. The decision to undergo an operation is therefore the result of a joint agreement between the ophthalmologist and the patient. Without surgery, the cataract will become denser and vision worse, and this may eventually affect fundus examination. Long-term cataract surgery has a current success rate of over 99.5%. 

The surgery:

The procedure is usually performed under local anaesthetic using powerful anaesthetic drops.

Once the eye has been anaesthetised, a micro incision (approximately 2.2 mm) is made at the extreme periphery of the cornea. Then, using a ultrasound probe, the nucleus of the crystalline lens is destructured without damaging the capsule separating it from the posterior part of the eye (this is known as ‘phako-emulsification’). The nucleus of the crystalline lens is then removed to be replaced by a flexible implant. This is inserted folded, then unfolded where the crystalline lens used to be. There are several types of implant.

Currently, the femtosecond laser is used in cataract surgery.

It enables a precise incision to be made, the rhexis, a circular ring around the anterior capsule, to be cut and the nucleus to be cut. The result is greater precision and the use of less ultrasound. Its value is still debated.

In around 1 in 3 cases, a secondary cataract develops, corresponding to an opacification of the posterior capsule (left in deliberately during the operation in order to hold the implant in place). If the patient is bothered by a drop in visual acuity or a sensation of haze, this secondary cataract is treated by laser.

The treatment is carried out in consultation after instillation of drops to dilate the pupil. It is simple, safe, fast (usually less than 10 seconds) and painless.

Dacryocystitis

Anthony SION Chirurgie reconstructrice et esthétique des paupières

Une dacryocystite est une inflammation, généralement d’origine infectieuse, d’un sac lacrymal. La dacryocystite se manifeste par un larmoiement continu typique, comme celui que l’on peut connaître lors d’un rhume. Elle survient essentiellement aux âges extrêmes de la vie: chez les nouveau-nés et les personnes âgées de plus de 70 ans. La dacryocystite est liée, chez les personnes âgées, à un rétrécissement des canaux lacrymaux. La baisse d’abondance des larmes entraîne un risque accru d’infection.

Dans les phases débutantes de l’infection, le traitement consistera en une antibiothérapie joint à une application locale d’un collyre antiseptique. 

Lorsque l’infection est plus évoluée, un abcès du sac lacrymal peut survenir, on observe alors l’apparition d’une tuméfaction rouge et douloureuse à la commissure des paupière, la maladie justifie dans ce cas une brève hospitalisation. 

Après de nombreuses récidives et selon la gêne du patient, une dacryo-cysto-rhinostomie peut être effectuée.

La dacryo-cysto-rhinostomie par voie externe est le traitement des obstacles situés sur le trajet du canal lacrymo-nasal. L’intervention est également réalisée par voie endonasale avec des résultats et des complications similaires, hormis l’absence de cicatrice avec cette technique.

Elle consiste à court-circuiter l’obstacle en réalisant une stomie entre le sac lacrymal et la paroi externe de la fosse nasale.

Une anastomose se fera entre le sac lacrymal et la muqueuse des fosses nasales. C’est une intervention préférable à la dacryocystectomie en cas de dacryocystite, parce qu’elle n’entraînera pas un larmoiement permanent pour le patient. L’intervention a un taux de réussite d’environ 90% et fait disparaître tous les symptômes. Elle est cependant plus difficile et plus longue qu’une dacryocystectomie et requiert un matériel et un savoir faire spécifique.

L’intervention consiste à extraire un morceau de la paroi osseuse entre le sac lacrymal et le méat moyen du nez, puis de suturer la muqueuse du sac à la muqueuse nasale du méat moyen.

Xanthelasma

Anthony SION Chirurgie reconstructrice et esthétique des paupières

Xanthélasma is a common condition that causes aesthetic discomfort and does not decrease with age. It is a xanthome plan palpébral (an infiltrate of histiocytic or macrophage cells filled with lipids – esterified cholesterol) that forms a yellowish plaque which gradually extends and darkens over the years on the upper or lower eyelid.

The best treatment is surgical, performed by an ophthalmologist, or if the lesions are small, they can be removed with a laser by a dermatologist.

However, recurrences are common, around 50%, which necessitates further treatments.

The major issue is the risk of ectropion due to skin retraction after multiple treatments.

Ectropion

Anthony SION Chirurgie reconstructrice et esthétique des paupières

Ectropion refers to the outward turning of the eyelid's free edge ("eversion" of the eyelid), causing a loss of contact between the eye and the eyelid.

The causes can be diverse:

Ectropion involutif: occurring due to tissue changes (progressive laxity) related to aging.

Ectropion paralytique: secondary to facial paralysis, related to certain myopathies, etc.

Cicatricial entropion: following burns or certain diseases (such as trachoma, etc.).

The treatment for ectropion is surgical and involves the correct repositioning of the eyelid tissues.
