Normally, the cornea and the natural lens have a curvature similar to the spherical surface of an almost perfectly round object, such as a soccer ball. In astigmatism, the curvature of the cornea and/or the natural lens looks more like that of a football with less elongated extremities. The image received by the retina depends, then, on the axes of the “ball”. Therefore, there are two different images for each axis of astigmatism. Astigmatism is the difference between the most powerful meridian and the least powerful one. Once again, it is possible to correct this vision impairment with the help of eyeglasses, contact lenses, laser surgery or intraocular lenses. Intraocular toric implants allow correcting corneal astigmatism following cataract surgery.
