The most common cause of corneal curvature (astigmatism) is genetic predisposition: the cornea does not grow evenly round, but slightly oval. As a result, the light hits the retina at two different points and the image remains blurred. In most cases, the defective vision is congenital and inherited from the parents.<\/p>\n\n\n\n

In addition to genetics, corneal diseases (such as keratoconus), injuries, and certain eye surgeries can also cause or exacerbate astigmatism. In this article, we will explain exactly how this occurs and which factors can worsen an existing corneal curvature.<\/p>\n\n\n\n

A distinction is made between regular astigmatism (correctable with glasses, contact lenses or permanently with a refractive eye laser treatment) and irregular astigmatism (best possible correction usually with dimensionally stable contact lenses, in selected cases also with topography-guided laser procedures).<\/p>\n\n\n\n

How does a corneal curvature occur?<\/h2>\n\n\n\n

A corneal curvature (astigmatism) is caused by different refractive powers of the eye or an uneven curvature of the cornea. The cornea is a clear, convex layer that covers the front of the eye and directs the incident light to the lens. When the cornea is unevenly curved, the incident light rays are not properly refracted and focused on the retina, resulting in blurred vision.<\/p>\n\n\n\n

People with astigmatism can see blurred, both near and far. You have difficulty recognizing contrasts and details, and objects may appear distorted or blurry. Astigmatism often occurs in combination with other refractive errors such as nearsightedness (myopia) or farsightedness (hyperopia).<\/p>\n\n\n\n
