Dr. Fu continues “the lens and cornea focus light on the Retina, the light-sensitive surface at the back of the eye. In astigmatism, the surface of the lens or cornea may have a different curvature in one direction compared to another. For example, someone with astigmatism usually has a cornea shaped more like a football than a basketball.” As a result, light is not focused to a single point on the back of the eye and this can lead to blurred vision.
Slight amounts of astigmatism usually do not affect vision, but larger amounts can lead to blurred vision, eyestrain, or even headaches. The most common ways of correcting astigmatism are with glasses or contact lenses. However, laser vision correction or lens replacement surgery can also reduce or eliminate astigmatism.
Some cases of astigmatism are caused by damage to the cornea from injury or from medical conditions such as keratoconus. Astigmatism from these causes can result in a type of astigmatism called irregular astigmatism. Eyeglasses usually cannot correct this type of astigmatism but technological advances now allow most types of astigmatism to be corrected with contact lenses or even refractive surgery. An eye exam by an eye care provider with experience in these technologies is needed to provide patients with all the available treatment options.
