Astigmatism is not considered an eye disease but, like nearsightedness or farsightedness, it is a refractive error of the eye. It develops from the improper curvature of the cornea and, less commonly, the lens. As a result of either type of astigmatism, your vision for both near and far objects appears blurry or distorted
Causes of Astigmatism
Astigmatism is a very common refractive error. In most cases, people with astigmatism are born with the condition. Some of the causes include:
- Irregularly shaped/cylindrical cornea
- Irregularly shaped eye lens
- Family history of astigmatism
- Eye injury
- Eye disease
- Eye surgery
Astigmatism Symptoms
Astigmatism can be detected and diagnosed by one of our qualified eye care specialists through a variety of comprehensive vision tests which include an eye exam, a light refraction test and corneal measurements. Some of the most common signs of astigmatism are:
- Blurred vision (for objects both far and near)
- An inability to read small print
- Constant squinting
- Headaches
- Eye irritation
- Eye strain
- Poor night vision
Treatment Options For Astigmatism
- Mild-Moderate Astigmatism: In most cases, astigmatism can be properly corrected with prescription eyeglasses or contact lenses (soft or gas permeable.) Our optometrists will be able to determine the best treatment option for your astigmatism.
- Severe Astigmatism: When astigmatism is severe, refractive surgery may be recommended. This involves altering the shape of the cornea through laser eye surgery. There are many different types of refractive surgeries and we can help you choose one suitable for your unique needs. Patients who suffer from retinal problems, corneal scarring and other eye diseases may not be good candidates for such surgery.
