In the eye there is a structure: ‘the lens’, which, as in a camera, focuses the images on the retina.
Cataract simply means that this lens is gradually becoming cloudy.
The causes are usually old age and, more rarely, diabetes, infection, trauma, and medication.
Sometimes cataract occurs at birth and cases often run in families.
Cataract development is typified by:
- Reduction of vision
- Reduction in colour observation
- Sometimes double vision and increased sensitivity to light.
Cataract treatment is essential when visual acuteness has reduced to such an extent that daily use of the eyes has become difficult (e.g. for driving, watching television, reading, and such like).
The usual cause of cataract is old age, but it can be caused by trauma, medication, heat, and such like.
The technique used for a cataract operation is called phako-emulsification of the lens. The patient is put under the operation microscope under local anaesthetic and sedation, and, if necessary, under the supervision of an anaesthetist.
- The front capsule of the circular shaped lens (capsulorexhis) is then removed via a tiny incision (2.2mm or smaller, so that sutures are not needed).
- After this, the lens which has become cloudy is shattered with ultrasonic vibrations and then removed via a delicate irrigation-aspiration system.
- Finally, after the remaining capsule has been cleaned, an implant lens is inserted. This is a pliable implant lens which can be monofocal, multifocal, or accommodative, depending on the case in question. Astigmatism is offset by relaxation incisions or toric implant lenses.
Basically, all forms of cataract can be normalised by this operation. In exceptional cases the technique has to be adapted in the event of insufficient lens suspension or if the rear capsule is damaged.
FEMTO CATARACT represents the newest in technology whereby lens extractions can be done by LASER instead of scalpels. The Femto laser has certainly proved its usefulness up to this point in the LASIK treatment of the cornea. For this laser procedure, first a computer guided scan of the eye (OCT) is done to create a 3D plan of the operation.
- 1. incisions in the eye
- 2. correction of astigmatism
- 3. precise incision around the anterior lens capsule
- 4. fragmentation of the cataract lens
Advantages to the Femto Cataract technique:
- increased safety and accuracy!
- with greater precision and reliability comes a higher likelihood of better results and a smaller chance of complications.
En tant que premier centre de Belgique, la Focus Eye Clinic a opté pour la précision suisse du ZIEMER Z8 LDV. La spécificité de cet appareil révolutionnaire est de travailler avec des pulses de faible énergie mais à une fréquence très élevée, en exerçant une pression minimale sur l’œil.
FEMTO LASER PHACO technique costs:
FEMTO LASER PHACO technique: +/- 650 euro
- A Femto Cataract operation is performed under local anaesthetic (eye drops are applied to anaesthetise the eye) under the supervision of an anaesthesiologist.
- You also receive a light sedative intravenously. This practice allows us to manage the general parameters of the operation.
- The procedure itself takes less than 15 minutes.
- You are in the eye clinic for about 2 hours.
- Well known technique (over 20 years of operations)
- Vision is restored almost immediately.
- The operation is not painful.
The same complications as with intra-ocular surgery:
- Some months or years later, cloudiness may arise from the rear capsule of the original lens. This is dealt with by further treatment with edema from the central retina.
- Detached retina
- and increase in ocular pressure may occur.
All these complications can be treated in a suitable manner, if they are diagnosed in time.
Monofocal lenses provide good sight correction for one distance (usually in the distance) and have always been the standard implant for cataract operations. However, the patient will still need glasses for close and medium vision.
The very latest solution is a multifocal implant lens which provides good vision for all distances. These lenses last a lifetime.
Recent improvements to monofocal or multifocal implant lenses are:
- lenses with a yellow filter to protect the macula
- aspheric lenses for better contrast vision at night
- toric lenses to correct astigmatism.
For health insurance providers and for the RIZIV (the national health insurance regulator), it makes no difference whether you are treated at a public hospital or at a private eye clinic like the Focus Eye Clinic.
The amount of repayment is the same, from about €435 to approx. €600 per eye (details here). [ http://www.focus-eye-clinic.com/praktisch/tarieven-ingrepen/ ]
When you hold hospitalisation insurance with DKV, AG Fortis, Axa, Ethias or Allianz, the standard cataract operation (implanting a monofocal lens) is 100% reimbursed.
