Implantable contact lens: EVO Visian ICL
In case of very pronounced visual defects, eye laser surgery reaches its natural limits (e.g. because of the individual thickness of the cornea). In these cases, an implantable contact lens is the optimal solution to correct your eyesight defect.
Contrary to normal contact lenses which are seated on the surface of the eye (on the cornea), the ICL is placed between the iris (the colored part of the eye) and the natural lens of the eye.
The implantation is a pain-free ambulatory intervention and lasts only about 15 minutes per eye. The eye is rendered insensitive with drops (no injection). Since the ICL is small and soft, it can be introduced surgically through a tiny opening (ca. 2.5 mm).
After the surgical implantation, the ICL is solidly anchored in the eye and protected – it needs neither cleaning nor a replacement. It is not felt or seen and can remain in the eye permanently. The ICL possesses an excellent tissue tolerance, since it is made of high-grade collamer which is not perceived by the human organism as a foreign body.
Thanks to an innovative technology and a fast healing process, which is further stimulated by the application of special eye drops, the eyes can rapidly recover after the intervention, and after a few days an improvement in visual acuity can already be observed.
The surgical success (or visual result) can be estimated in a highly precise way, and the intervention is reversible – that is, the lens can be surgically removed from your eye without further consequences.

Lens replacement (Clear Lens Extraction)
The lens exchange can be performed in persons from about age 50 with myopia, hyperopia, astigmatism or presbyopia. The natural lens is replaced in these procedures by an artificial lens with optimal refractive power.
In times past, only «one-power lenses» were available, that provided a sharp image for only one distance range. Usually the power of the lens was chosen to give the patient good distant vision, while for the short range the lifelong use of glasses was still required.
Thanks to a special surface design, the newest artificial lenses now offer good near and distant vision. They thus have the property of imitating the accommodation of the natural lens (adjustment of the refractive power). All eyesight defects (including presbyopia) can thus be corrected durably and precisely.
The implantation of artificial lenses is a pain-free operation. By the use of drops (no injection) the eyes are rendered insensitive. The eye’s own lens is replaced by an artificial lens with the best possible correction. Thanks to an advanced technology and a fast healing process that is further sustained by the application of special drops, the eyes can recover soon after the treatment, and an improvement in visual acuity can thus already be noted after a few days.
In the conventional method, the eye lens is siphoned off by ultrasound from the border of the cornea via an incision of only ca. 2.5mm (made with a scalpel) and the new artificial lens is then introduced into the eye via a small tube. It unfolds in the eye and takes the place of the normal eye lens.
This technique is also applied routinely in case of an opacification of the eye lens (cataract) and is among the most often performed operations worldwide.
For a long time, this method remained almost witrhout major improvement, until finally, a few years ago, laser technology also conquered this domain. With the laser technology «Femto Phako» it is now possible to operate without a scalpel and to make the implantation of modern artificial lenses both more precise and simpler.
As one of the first eye centers of Switzerland, the Eye center Dr. Aus der Au has been using the novel technique called «Femto Phako» since 2012, which permits highly precise and tissue-sparing interventions on the eye. With this treatment, the tissue of the eye can be worked on even more precisely and sparingly. Several steps, previously carried out by the physician by hand, have been replaced. The lens exchange thus becomes, on the one hand, more precise, since the artificial lens is positioned more precisely, and on the other hand also safer, since laser incisions are always more precise than those guided by hand!
