The Causes of Astigmatism: Genetics, Eye Shape, and More

Understanding Astigmatism: Causes, Symptoms, and Treatment

Astigmatism is a common vision condition that can lead to blurry or distorted vision, making daily activities like reading or driving more challenging. While it may sound concerning, astigmatism is manageable with the right treatment. Dr. Scotty Gadlin at Athens Eye Consultants in Athens, GA, helps patients understand what causes astigmatism, how it affects vision, and the best ways to correct it.

What Is Astigmatism?

Astigmatism happens when the cornea or lens inside the eye is not perfectly round. Instead of a smooth, evenly curved shape, the cornea has an irregular, football-like curvature. This uneven surface prevents light from focusing properly on the retina, causing blurred or distorted vision at various distances. Fortunately, astigmatism is a common condition that can be corrected through prescription lenses or refractive procedures.

What Causes Astigmatism?

Genetics plays a significant role in astigmatism, as many people inherit the shape of their cornea from family members. Some people are born with a slight irregularity in the eye's curvature, leading to astigmatism at an early age. Eye injuries or past surgeries can also alter the cornea's shape, resulting in vision changes. Some conditions, like keratoconus, may cause the cornea to thin and become cone-shaped over time, leading to more severe astigmatism. In some cases, aging or eye diseases may contribute to changes in the cornea’s structure.

Can Astigmatism Get Worse?

Astigmatism can change over time, particularly in childhood and adolescence. It can also shift with age, requiring periodic adjustments in prescription lenses. Regular eye exams help monitor these changes, ensuring that vision remains clear and properly corrected.

How Is Astigmatism Treated?

Many individuals manage astigmatism effectively with glasses or contact lenses. Special toric lenses are designed to correct the irregular curvature of the eye and provide sharp vision. For those seeking a more permanent solution, refractive surgery, such as LASIK or PRK, can reshape the cornea to eliminate the need for corrective lenses. Some patients with severe astigmatism benefit from rigid gas-permeable or hybrid contact lenses for enhanced clarity and comfort.
