Understanding the Astigmatism Severity Index | Ophthalmology Vision Clinic

Astigmatism is a frequent eye condition that occurs when your eye’s cornea or lens isn’t perfectly shaped. As a result, the light entering your eye is affected, which can cause blurred or distorted vision. This can make it hard to focus on objects both near and far. Fortunately, this condition can be corrected with glasses, contact lenses, or LASIK eye surgery. It’s crucial to understand the severity of your astigmatism to manage it effectively with the right treatment.

Here’s how to find astigmatism measurements on your glasses prescription:

1. The first number indicates whether you’re nearsighted (minus sign) or farsighted (plus sign). The larger the number, the stronger the lens power needed to correct your vision.

2. CYL indicates the severity of your astigmatism in diopters.

3. Axis value shows the location of your astigmatism in degrees, ranging from 0 to 180.

The Astigmatism Severity Scale is essential to understand the seriousness of your condition to find the suitable treatment. The scale is divided into four categories: mild, moderate, severe, and extreme.

Mild Astigmatism is less than 1.00 diopter and quite common. The symptoms are often so mild that you might not even notice it. Moderate Astigmatism ranges from 1.00 to 2.00 diopters and may require treatment to function daily. Severe Astigmatism ranges from 2.00 to 3.00 diopters and usually requires corrective glasses or contact lenses. Extreme Astigmatism is anything beyond the severe scale and typically requires urgent medical attention due to the severity of its symptoms.

To diagnose astigmatism, doctors usually use an eye chart, a phoropter (a fancy mask-like device used to tweak your vision), an autorefractor (a device measuring how light changes as it moves through your cornea and lens), and a keratometer or corneal topography to map out the shape of your cornea.

The need for glasses is largely determined by the degree of astigmatism; minor astigmatism may not need glasses at all. However, if your astigmatism is moderate to severe, glasses can help correct your vision and lessen blurriness or distortion. It’s always advisable to get your eyes checked by an eye care specialist to determine the best treatment.

LASIK eye surgery can be a great solution for correcting severe astigmatism. The procedure involves using a laser to reshape the cornea, correcting the irregular curvature causing the astigmatism. This can give you clearer vision and reduce your dependence on glasses or contacts.

If you’re diagnosed with Astigmatism, you have several treatment options, such as eyeglasses, contact lenses, orthokeratology, and refractive surgery.

Some FAQs:

1. Is 180-axis astigmatism harmful? In general, it can cause blurred or distorted vision. An eye care specialist can recommend the best treatment options.

2. Are you awake during LASIK surgery? Yes, your eyes remain open throughout the procedure, which only takes a few minutes.

3. Is 0.75 astigmatism noticeable? It might cause some blurriness or distortion in your vision, especially if you have sensitive eyes or high visual demands. However, how each person perceives it can vary.
