Eye conditions like astigmatism are so common that it is easy to overlook their signs. Here, we point out some of the details about this problem so you can get the help you need when it will be the most effective.

  • Astigmatism is related to the cornea, a structure that light passes through after entering the eye. Normally, the cornea is nicely round, like a ball. Astigmatism involves an elongated shape that is more like an egg or football. The lengthened curvature of the cornea alters the distribution of light, leading to some degree of blurred vision.
  • It is also possible for astigmatism to develop on the lens of the eye rather than the cornea. This is referred to as lenticular astigmatism. Like corneal astigmatism, this type affects both near and distance vision.
  • Genetics plays a role. Though it is possible that astigmatism could result from an eye injury or surgery, researchers believe that there is also a strong chance that the curve of the cornea could be an inherited trait, just like eye color.
  • Children can develop astigmatism. It is important to schedule early and regular eye exams for children. Without proper detection and treatment, astigmatism in a child could lead to "lazy eye" (amblyopia).
  • Astigmatism can develop at varying degrees. Depending on the degree of curvature in the cornea, a person with astigmatism may experience symptoms including nearsightedness or farsightedness, eye fatigue, light sensitivity, and headaches.

LASIK Can Correct Astigmatism

There is value in understanding what might cause astigmatism and how to spot the symptoms of this condition. However, what is valuable is knowing what to do about blurry vision. At Pasadena Eye Associates, LASIK is often the ideal solution for this problem. LASIK is a laser vision-correcting procedure that works by reshaping the cornea. The technique was initially developed to treat nearsightedness and farsightedness but, over time, also demonstrated excellence in correcting astigmatism. We perform LASIK with the most sophisticated laser technology to achieve the best possible outcome for each patient.
