  • Astigmatism

    Astigmatism is a natural and commonly occurring cause of blurred or distorted vision that is usually associated with an imperfectly shaped cornea. It is a common eye condition that's usually corrected by eyeglasses, contact lenses, or surgery. Astigmatism is caused by an eye that is not completely round and occurs in nearly everybody to some degree.

  • Astigmatism

    Astigmatism is usually associated with an imperfectly shaped cornea. The exact cause in not known. People with undetected astigmatism often have blurred vision which can be associated with fatigue and eyestrain. Astigmatism may occur with other vision problems such as near sightedness and farsightedness. The possible treatments for Astigmatism are glasses, contact lenses, and even vision correction procedures.

  • Astigmatism

    Irregular astigmatism is far less common and is associated with abnormal conditions affecting the cornea (for example, keratoconus). This condition is more effectively treated with rigid gas permeable contact lenses or corneal procedures. Age is the most important demographic factor associated with different types of refractive errors. The prevalence of astigmatism was 25.64% (95%CI: 23.76&27.51). The rate of hyperopia showed a significant increase with age in individuals >15 years. The prevalence of astigmatism was 25.64%.
