Astigmatism, a common refractive error affecting the eye's shape, can be a source of frustration for many. A key question many people have is whether their astigmatism can worsen over time. The answer, unfortunately, isn't a simple yes or no. The progression of astigmatism is complex and depends on several factors. Let's delve deeper into this important topic.
What is Astigmatism?
Before exploring whether astigmatism can worsen, it's crucial to understand what it is. Astigmatism occurs when the cornea (the eye's front surface) or lens is irregularly shaped, preventing light from focusing correctly on the retina. This results in blurry vision at all distances. Unlike nearsightedness (myopia) or farsightedness (hyperopia), which are primarily axial (length of the eye) issues, astigmatism is related to the curvature of the eye's surfaces.
Can Astigmatism Get Worse Over Time?
The simple answer is yes, astigmatism can get worse, but it doesn't always. The severity and progression of astigmatism vary greatly depending on several factors:
-
Age: Astigmatism often develops during childhood, and its progression tends to slow down or stabilize during adulthood. However, certain conditions can cause changes in the cornea's shape even in adults, leading to astigmatism worsening.
-
Underlying Medical Conditions: Conditions like keratoconus (a progressive thinning of the cornea), eye injuries, or certain eye surgeries can significantly impact corneal shape and thus worsen existing astigmatism or induce it in individuals who previously didn't have it.
-
Genetics: Genetic predisposition plays a role in the development and progression of astigmatism. If family members have experienced worsening astigmatism, the likelihood increases.
Does Astigmatism Always Get Worse?
No, astigmatism does not always get worse. For many individuals, the condition stabilizes during adolescence or early adulthood, requiring little to no change in their corrective lenses over many years. Regular eye exams are crucial for monitoring any changes.
What Causes Astigmatism to Worsen?
Several factors can contribute to the worsening of astigmatism:
-
Keratoconus: This progressive corneal disorder is a leading cause of astigmatism worsening, potentially requiring specialized treatment beyond glasses or contacts.
-
Eye Injuries: Trauma to the eye can disrupt the cornea's shape and induce or worsen astigmatism.
-
Eye Surgery: Certain eye surgeries, while aimed at correcting vision, can sometimes inadvertently alter corneal shape and introduce or worsen astigmatism.
How Often Should I Have My Eyes Checked for Astigmatism?
Regular eye examinations are crucial, especially for children and young adults. The frequency of these checkups can vary based on individual needs and age, but it's generally recommended to have your eyes checked at least once a year. This allows for early detection of changes in astigmatism or other eye conditions.
Can Astigmatism Be Corrected?
Yes, astigmatism can be effectively corrected using various methods, including:
-
Eyeglasses: Standard eyeglasses with cylindrical lenses correct astigmatism.
-
Contact Lenses: Contact lenses, especially toric contact lenses, can provide sharper vision correction by conforming to the eye's unique shape.
-
Refractive Surgery: Procedures like LASIK surgery can permanently reshape the cornea to correct astigmatism.
Can Astigmatism Be Prevented?
While there isn't a foolproof way to prevent astigmatism, protecting your eyes from injuries and seeking prompt medical attention for any eye problems can help minimize the risk of its worsening.
