Astigmatism, also called corneal curvature, is a refractive error of the eyes. A corneal curvature often occurs in combination with nearsightedness and farsightedness. However, astigmatism differs from nearsightedness and farsightedness in that the cause is not a deformation of the eyeball, but a deformation of the cornea.
People with astigmatism see distorted at all distances, and for example, they see points as lines. The severity of the corneal curvature can vary, so that round objects may be perceived as oval. Astigmatism can be corrected with glasses, contact lenses, or by laser.
Description
A corneal curvature is when the cornea, also called the cornea, is not evenly curved but unevenly curved. The medical term for corneal curvature is “astigmatism”. Normally, the cornea together with the eye lens is responsible for bundling and focusing incoming light rays. These should hit a single point on the retina. This process enables sharp vision.
Due to the uneven curvature of the cornea in astigmatism, the light cannot be properly bundled. The incoming light rays therefore do not meet at a single point on the retina as they normally should, but they converge in sequence.
As a result, no single clear point is formed on the retina, which leads to blurred vision.
Your eye doctor in Frankfurt will be happy to help you clarify any further questions you may have about astigmatism.
Symptoms
Corneal curvature only becomes noticeable when it is more pronounced. As soon as this happens, you should see a doctor immediately. We, your eye doctor in Frankfurt, are then happy to help you.
Blurred vision both near and far can be symptoms of corneal curvature. But headaches and eye pain can also be signs. Other symptoms can be constant squinting of the eyes and difficulty concentrating. The symptoms mentioned can negatively affect your daily life. Due to blurred vision, you can put yourself and others at risk, which is why we strongly recommend an examination.
The eye is constantly working to correct the blurred image caused by the curvature of the cornea. The constant strain on the eye muscles leads to eye and headaches.
Treatment
Your eye doctor in Frankfurt will diagnose corneal curvature and point out the treatment method. Once the diagnosis is known, the type of treatment can be determined.
Glasses with so-called cylindrical lenses can be a possible visual aid. Appropriately curved contact lenses are also a common aid.
