PRELEX, PRESBYOPTIC LENS EXCHANGE PRESBYOPIA-TIRED SIGHT

PRELEX is a term used to describe lens exchange with multifocal intraocular lens. While the application of this technology is new, the surgical techniques employed have proved to be successful over many years of use.
The cornea (the outside part of the eye) and the crystalline (eye’s natural lens) work together to focus light that comes into your eye. The lens, which is flexible when you are younger, becomes increasingly inflexible as you grow older, often after you have passed the age of forty. Consequently, you have a difficult time focusing on objects. This condition is known as presbyopia.

The onset of presbyopia has traditionally meant that you are relegated to using glasses for clear vision. What is more, even those individuals who have received laser vision correction (myopia-hyperopic–astigmatism) will need glasses or contacts to restore their full range of sight when they are over forty.

PRELEX offers a solution. PRELEX works on the lens inside the eye. Consequently, your vision after the procedure will be stable und unlikely to change over time. In addition, cataract surgery will not be necessary later in life. The multifocal lens that is used to replace yours eye´s natural lens will provide you with clear vision at all distances, giving you little or no dependence on traditional or progressive bifocal glasses.

Prelex is a modern and advanced technique to correct the presbyopia. It is made ambulant without hospitalisation and only a few minutes are necessary for each eye. The treatment will be made with local anaesthesia. If you have pre-existing astigmatism the surgeon can try to correct it with an “Arquata Queratotomy” with micro incision in the corneas border. The treatment will be made from a corneal micro incision and it is necessary to use a special apparatus called Phacoemulsificator, which dissolves the natural lens or crystalline. After that the multifocal lens will be folded and inserted through the same micro-incision and will be placed at the best place. The incision is so little that it does not require stitches after finishing the treatment.

You will go home shortly after the operation is finished and relax for the rest of the day. Most patients report improvement in their vision almost immediately after the procedure. Most patients return to their normal activities within a day or two.

In 20 % of the cases, patients need an adjustment dioptres within 2-3 months of the application of the Excimer Laser. That is because in some patients the computer biometric calculus of the multifocal lens has to be readjusted by Laser Excimer because of individual factors. This procedure is called PRELEX BIOPTIC and the results are excellent.

PRELEX is for those who:

· Want to be less dependent on glasses or contacts for far and near vision.
· Are outside the corrective range of LASIK and other refractive procedures.
· May be showing signs of clouding in their natural lens even though this clouding is not yet interfering with vision.
· Have no health issues affecting their eyes.

Realistic expectations:

It is extremely important to understand that with multifocal implants you are getting a new “visual system”. That means that it will naturally take time for your brain to adjust to a new visual system.

Following PRELEX , it is always told to the patient that they will see halos around objects, especially at night, but this situation will become less and less noticeable being possible that it totally disappears.

The goal of PRELEX surgery is to reduce or eliminate your dependence on glasses or contact lenses. However you may not achieve the results you desire and your Doctor of CIMO cannot guarantee that, he only can give you relevant statistics and in more than 95 % cases the patients are quite happy.

PRELEX uses a multifocal lens. This is the most effective lens you can find. This lens has been approved by the FDA for cataract surgery . In our clinic, CIMO use the ARRAY Allergan SA40 lens, imported from the United States.
