Can Astigmatism Be Corrected? A Look At Diagnosis And Treatment

Are you experiencing distorted vision or blurriness? This could be astigmatism. It occurs when the shape of the cornea or lens gets disturbed, affecting how light enters and focuses on the retina.  Can astigmatism be corrected? That’s a common question.

Yes, there are different ways to correct it and help you see clearly again. This blog explores the causes, correction methods, and related concerns of astigmatism in detail.

What Causes Astigmatism?

The uneven shape of the cornea leads to the problem of astigmatism (corneal astigmatism) or the lens inside the eye (lenticular astigmatism). In the case of normal eye condition, the cornea is shaped in a perfect round condition, but if astigmatism occurs, the shape of the cornea gets a little affected, like an uneven curve.

This condition can be present genetically or can be developed later due to having any accidental injury, surgeries, or disease. In some cases, astigmatism is linked with other refractive errors like nearsightedness or farsightedness.

Can Astigmatism Be Corrected?

Yes, astigmatism can be corrected. The specialist does the treatment that focuses light evenly onto the retina to achieve clear vision. There are three common methods:

1. Prescription Eyeglasses: The easiest solution to the problem is the right prescription glasses.
2. Contact Lenses: Here, it supports the side vision too, and in this, you don’t need to carry or wear glasses all the time. Once the lenses are fixed, the issue is solved.
3. Refractive Surgery: LASIK and PRK are the surgical methods that shape the cornea in the form it should be. These options are best for those who don’t want to depend on any support like glasses or lenses, but not everyone is a right fit.

An eye specialist will determine the best correction method based on the type and severity of astigmatism.

How Is Astigmatism Diagnosed During An Eye Exam?

Astigmatism is usually found during a routine eye check-up. Eye doctors use the following tests:

• Visual Acuity Test: Check how clearly you see the letter from a distance
• Keratometry: Check the structure of the cornea.
• Refraction Test: Check the correct prescription that can support clear and comfortable vision.

we understand the value of eye exams when they help catch a serious problem early, before it gets worse with age.

These tests can detect issues like astigmatism and help manage them on time, so your daily life stays easy and comfortable.

Symptoms may include:

• Noticing glare and rings around lights

Types Of Astigmatism

There are three main types:

• Myopic Astigmatism: One or both meridians are nearsighted.
• Hyperopic Astigmatism: One or both meridians are farsighted.
• Mixed Astigmatism: One meridian is nearsighted, and the other is farsighted.

Each type affects vision differently and requires an approach that is tailored according to each individual eye condition, age, and overall health. 

When Should Astigmatism Be Treated?

Treatment is usually recommended when astigmatism starts interfering with daily activities. Common symptoms include:

• Blurred or distorted vision
• Eyestrain or headaches
• Trouble reading, using screens, or seeing at night

Children may not realize they have vision problems, so regular eye exams are essential for early detection and treatment.

Can Astigmatism Be Prevented?

Astigmatism cannot be prevented in most cases because it’s usually inherited or caused by natural changes in the eye’s shape. 

However, taking care of eye health can help in reducing eye strain and detecting problems before they take a major form and need strong surgical intervention.

 Tips include:

• Taking short breaks during prolonged screen exposure
• Protecting eyes from getting injured wherever possible
• Going for regular eye checkups
