Verfahren für ältere Patienten, weitsichtige Patienten und Patienten, die eine altersbedingte Linsentrübung haben und kurzsichtig sind.
Hier wird die körpereigene Linse gegen eine Kunstlinse ausgetauscht. Da bei älteren Patienten die Akkommodationsfähigkeit (Fähigkeit der Linse, sich automatisch auf verschiedene Entfernungen einzustellen) eingeschränkt ist, kann der Patient sich bei diesem Verfahren für eine implantierbare Multifokallinse entscheiden, welche bewirkt, dass nach der Operation keine Lesebrille notwendig sein wird. Sollte der Patient sich für eine monofokale Linse entscheiden, wird es notwendig sein, nach der Operation eine Lesebrille zu verwenden.
Intraokulare Linsen (ICL, Artisan)
Die Implantation einer phaken intraokularen Linse wird bei denjenigen Fällen bevorzugt, bei denen eine LASIK kontraindiziert ist, z.B. bei stark kurzsichtigen Patienten oder bei Patienten, die eine umkehrbare Operation bevorzugen.
Bei dieser Methode wird eine Kunststofflinse in die Hinterkammer des Auges, also zwischen körpereigener Linse und der Iris implantiert. Die Akkomodation (Fähigkeit des Auges, sich auf Nah- und Fernsicht einzustellen) der eigenen Linse bleibt erhalten. Das Verfahren ist für junge Patienten geeignet, da diese Fähigkeit der körpereigenen Linse im Alter (ab ca. 45 Jahren bei normalsichtigen Personen) abnimmt.

Refractive Lens Exchange (RLE)
If you are tired of wearing glasses, but have been told that you are not a candidate for LASIK, there is another vision correction option that may be right for you. It’s called Refractive Lens Exchange (RLE). It can also be called Clear Lens Extraction (CLE).Unlike LASIK and other refractive surgery techniques that correct vision by changing the shape of the cornea, RLE corrects your vision by changing the focusing power of the eye?s lens. To do this, we replace your natural lens with a new intraocular lens (IOL).Like the lens of a camera, which focuses images sharply on the film, the eye’s lens focuses light and images on the retina at the back of your eye. With RLE, your natural lens is replaced with an IOL selected to give you the best vision for your needs. RLE is well suited for people over 40 because that is the age that most of us begin to lose the ability to focus up close. This occurs when the natural lens becomes less flexible, and no longer accommodates as well to changing its focus from distant to near vision. Then reading glasses or bifocals are needed for close work.Some IOLs used in RLE have a fixed focal length and do not accommodate. If you select this type, you may prefer to have your new lens provide sharp distance vision for driving, golf, and similar activities. Or you may want near vision for reading, computer work and other close activities. Or you can choose Monovision where one eye is corrected to see near. The choice is yours. Another option is a special type of multifocal IOL that allows the eye to focus both up close and far away. This unique lens allows the eye to focus naturally without glasses. We only use the best intraocular lenses available from Alcon or Zeiss which give the optimal results. You can visit the Alcon (http://www.acrysofrestor.com/) or Zeiss (http://www.zeiss.de/C125679E00525939/ContainerTitel/acrilisa/$File/index_en.html) web sites for more information.Before the procedure, your eye is carefully measured using precision state-of-the-art laser and ultrasound instruments. These measurements are entered into a sophisticated formula to calculate the exact corrective power of your intraocular lens.While RLE is not right for everyone, it may be the option you are looking for. To find out if you are a candidate for RLE, or for one of
the other refractive procedures available at Kaskaloglu Eye Hospital please contact us. Here is a useful link for information on RLE:http://www.allaboutvision.com/visionsurgery/refractive-lens-exchange.htm
ICL ( www.staar.com)
The STAAR Visian ICL and the Visian TORIC ICL (Visian TICL?) are posterior chamber phakic intraocular lenses. Made of Collamer,
Staar’s proprietary collagen copolymer, the lens rests behind the iris in the ciliary sulcus. This unique material contains a small
amount of collagen, which provides excellent biocompatibility and superior optical capability. The lens is gently folded and injected
into the anterior chamber through a 3.0mm, temporal, clear corneal incision. The ICL is then carefully positioned by manipulating the
footplates of the lens posterior to the iris plane and into the sulcus
Q. Am I a candidate for the ICL?
A. The best candidates for the Visian ICL are between the ages of 21 and 50, with moderate to severe myopia or hyperopia with or
without astigmatism.It is best if the candidate has not had any previous ophthalmic surgery and does not have a history of ophthalmic
disease such as glaucoma, iritis or diabetic retinopathy.
Q. What are the advantages of the ICL?
A. The Visian ICL and Toric ICL are capable of correcting a wide range of myopia, hyperopia and astigmatism without the removal or
destruction of corneal tissue. The ICL is a small, foldable, injectable lens that is inserted through a tiny, 3 mm incision that does not
require sutures. The ICL provides predictable refractive outcomes and excellent quality of vision due to its placement inside the eye,
as well as its optical performance. The lens is made of a superior lens material called Collamer, which provides unparalleled
Q. What if a patient’s vision changes?
A. If there are major changes in ones vision the Visian ICL can easily be removed and replaced, or another procedure can be done at
any time. With the ICL, one can still wear glasses or contact lenses if necessary. The ICL does not help presbyopia, or the need for
reading glasses due to age.
Q. Can they dry out or get dirty like a contact lens?
A. No. The Visian ICL is designed to remain in place within the eye without maintenance. An annual examination done by your
ophthalmologist is recommended to make sure that everything is fine.
Q. Can the ICL be seen by the naked eye?
A. No. Because the lens is positioned behind the iris, neither you, nor an observer will be able to identify the lens in place. The
cosmetic appearance of the Visian ICL is perfect, and there is no way for a non-professional to notice that a visual correction is in
Q. What are ICLs made of?
A. The material is called Collamer, a collagen co-polymer that contains a small amount of purified collagen. It is very biocompatible
(doesn’t cause a reaction inside the eye) and stable. It also contains an ultraviolet light filter. This material is proprietary to STAAR
Q. What is involved in the ICL procedure?
A. The ICL surgery is performed on an outpatient basis, which means that the patient has surgery and leaves the same day. Please note
that someone will have to drive the patient to and from surgery. A light, topical or local anesthetic is administered and there is very
little discomfort and normally no pain associated with the procedure. Some drops or perhaps oral medication may be prescribed and a
visit is usually scheduled the day after surgery.
ARTISAN®/ ARTIFLEX® lenses (www.artisanlens.com)
Nowadays people from all around the world prefer not to be dependant on spectacles or contact lenses. They face problems while
wearing these or they feel that they no longer fit in a modern lifestyle. For these people refractive surgery could be a solution.
The ARTISAN®/ ARTIFLEX® lens is one of the most modern techniques of refractive surgery. This lens is a reliable, well performing
alternative for the popular laser treatments.
What’s an ARTISAN® or ARTIFLEX® lens?
An ARTISAN®/ ARTIFLEX® lens is an implantable lens that is implanted in the eye by an eye surgeon. The lens will stay there
permanently and therefore you will be able to see clearly all the time; your glasses or contacts will not bother or limit you anymore. It
seems as though you have no “refraction problem” any more. The lens needs no maintenance en can stay in your eye for the rest
of your life.
If you should need to replace the lens for any reason, this can be done without any problem in most of the cases. The lens can be
implanted in people of between 18 and 60 years of age, who meet certain conditions. The lens is available for shortsightedness (-3 to ?
23,5 diopter) and long-sightedness (+1 to +12 diopter); the cylinders (astigmatism) can also be corrected with the ARTISAN® lens. The
ARTISAN®/ ARTIFLEX® lens offers no solution for presbyopia.
