Astigmatism is a common vision condition that affects the way light enters the eye, causing blurred or distorted vision. Dr. John Meyers explains what astigmatism is, how it’s diagnosed, and the available treatment options.

1. What is Astigmatism?

Astigmatism occurs when the cornea or lens has an irregular shape, causing light to focus unevenly on the retina. This irregular curvature leads to blurred or distorted vision at all distances.

2. Symptoms of Astigmatism

Common symptoms of astigmatism include:

• Blurred or distorted vision
• Eye strain or discomfort
• Headaches
• Difficulty seeing at night
• Squinting to see clearly

3. Causes of Astigmatism

Astigmatism can be present from birth or develop later in life. It can occur in combination with other refractive errors like myopia (nearsightedness) or hyperopia (farsightedness). The exact cause of astigmatism is not known, but genetics may play a role.

4. Diagnosing Astigmatism

Astigmatism is diagnosed through a comprehensive eye exam, which includes:

• Visual acuity test: Measures the sharpness of your vision using an eye chart.
• Keratometry: Measures the curvature of the cornea.
• Corneal topography: Maps the surface curvature of the cornea in detail.
• Refraction test: Determines the exact prescription needed for corrective lenses.

5. Treatment Options for Astigmatism

1. Eyeglasses

Eyeglasses with special cylindrical lenses can correct the way light enters the eye, providing clear vision. This is a simple and effective treatment for most cases of astigmatism.

2. Contact Lenses

Toric contact lenses are designed specifically for astigmatism, providing clear and stable vision. Both soft and rigid gas permeable (RGP) toric lenses are available, depending on your needs and preferences.

3. Refractive Surgery

Refractive surgery, such as LASIK or PRK, can reshape the cornea to correct astigmatism. These procedures are suitable for some patients and can reduce or eliminate the need for glasses or contact lenses.

4. Orthokeratology (Ortho-K)

Ortho-K involves wearing specially designed rigid contact lenses overnight to temporarily reshape the cornea. This can provide clear vision during the day without the need for glasses or contact lenses.

6. Managing Astigmatism

Regular eye exams are crucial for managing astigmatism and ensuring your prescription remains accurate. Dr. Meyers can provide personalized recommendations based on your specific needs and lifestyle.
