For a long time, this method is used to correct nearsightedness by placing an extra lens in front of the own natural lens.This can possibly correct myopia from -1.0 to -23.5 with an ICL-lens
Although the calculation of the lens power is extremely accurate, it might be possible that not 100% of patients will be completely free of spectacles. It is therefore possible that after the surgery you may still require glasses, albeit with a much lower strength than before. The major difference of this procedure compared to a laser treatment is that, this treatment is reversible, while laser surgery is irreversable.
Furthermore, like any other person at middle age with ‘normal eyes’ you may require reading glasses after the age of 45.
A myopic eye is usually longer than the normal eye. In the myopic eye the focal point of the light rays that come from a distant point, lies in front of the retina: the image on the retina is blurred. Light rays, that come from a near point, are focused clearly on the retina, which is why a nearsighted person sees better close by than far away.
The farsighted eye is usually shorter than a normal eye. The focus of the light ray lies behind the retina. The retina produces a blurred image for the person in question, but through accommodation (adjusting the lens), the picture occasionally looks sharp. This is why the visual aquity far away is slightly better than for near.
Cylindrical deviation (astigmatism)
Astigmatism is an abnormal curvature of the cornea. When the curvature of the cornea is not in the form of a sphere like for instance a football, but more in the form of; for example a rugby ball, we speak of astigmatism. Astigmatism can occur by itself or in combination with near-or farsightedness. Astigmatism causes a blurred image as well at far as nearby.
The ICL lenses require no maintenance and can basically remain in the eye forever. If there is any reason at all for replacement of the lens, it is, in most cases possible without any problem.
All these lenses meet strict safety requirements.
This lens will probably remain in the eye for a long time, but not forever. If you would ever be diagnosed with cataract, your own lens and the ICLlens will be replaced by 1 new artificial lens. We can also always remove the lens if there is any medical indication to do so. Therefore, it is a must, for the rest of your life, to have annual checkups so that we can monitor the condition of your eye.
No surgery is without risk. Even if the risk is very minimal, complications may always present themselves.
Among the possible consequences of these procedures are the perception of halos, reduced sharpness of vision, even with correction, troubles with night vision, an inner eye infection, a distortion of the image, the development of cataracts or glaucoma. These are unwanted secondary effects, but specific to the type of surgery. With an adequate preoperative examination, however, the risk of having side effects is very low.
