Astigmatism is an eye defect in which the optical system is curved differently in different planes. Therefore, the rays do not break into a place and so they create a shadowy or distorted image on the retina. Most often it is about the change in the curvature of the cornea, in some cases also that of the lens.

The truth is that astigmatism in patients rarely occurs on its own, most often it is accompanied precisely by a refractive error. The wrong curvature of the cornea in most cases is congenital and at low astigmatism (of the cylinder) you can not even notice a deviation of vision. But if the deformation of the cornea is greater, vision needs to be corrected by special lenses, which are usually called cylinders.

The astigmatism can also arise as a result of eye injury or can also be part of cataracts. But it’s not a serious diagnosis – you can live a comfortable life with the diagnosis, as with any other refractive error. Either you go the way of glasses, contact lenses, or you choose a more convenient type of laser surgery.
