Risk factors for Astigmatism

A risk factor is something that increases your chance of getting a disease or condition.

The following factors increase your chances of developing astigmatism. If you have any of these risk factors, tell your doctor:

• Heredity-a family history of eye disease or disorders, such as keratoconus
• Eye surgery-certain types of eye surgery, such as cataract (lens of the eyes are cloudy) removal (less common with modern techniques)
• A history of corneal scarring or thinning
• A history of excessive nearsightedness (a visual defect where distant objects appear blurred) or farsightedness (a visual defect where distant objects are seen better than objects that are close)
