Astigmatism is an abnormality of the cornea and results in blurred vision from far and near. The main cause is deformation of the cornea. Its curvature is irregular: it has an oval shape instead of being rounded. The image of the objects does not form exactly on the retina and the shape of the cornea disturbs the focus.
There are two kinds of astigmatism: the first, and most frequently occurring, is corneal, and the second involves the lens.
Astigmatism can appear from birth. If it is progressive and evolves over time, the cause may be a keratoconus. Additionally, this disorder is often found together with myopia or hypermetropia. Contrary to what one might think, it is possible to operate on this vision impairment. Our ophthalmologist surgeons practice laser surgery to treat sufferers of astigmatism whether they also have other visual impairments or not.
To correct astigmatism with laser surgery, the most widely practised technique is Lasik. The laser makes the curvature of the cornea uniform. The operation therefore consists in increasing or reducing the curvature according to the meridians of the cornea.
The LASIK technique can treat all astigmatisms. Depending on the specifics of your vision, the surgeons will carry out the most suitable technique. In this way, you are of receiving personalised care.
Astigmatism is expressed in dioptres and can be considered as:
|from 0 to 1 dioptre|
|from 1 to 2 dioptres|
|more than 2 dioptres|
