What is Astigmatism?

Astigmatism is a common refractive error in which the shape of the eye is irregular, leading to blurred or distorted vision. Normally, the cornea (front surface of the eye) is round like a ball, but in astigmatism, it becomes oval or uneven. This causes light to focus incorrectly on the retina, resulting in unclear vision at all distances.

Astigmatism can occur alone or along with other vision problems such as:

  • Myopia (near-sightedness)
  • Hyperopia (far-sightedness)

Astigmatism | Causes, Symptoms, Diagnosis & Treatment

Types of Astigmatism

Astigmatism is classified based on the part of the eye affected:

1. Corneal Astigmatism

Occurs when the cornea has an irregular shape.

2. Lenticular Astigmatism

Occurs due to irregularities in the eye lens.

3. Myopic Astigmatism

Blurred vision for distant objects.

4. Hyperopic Astigmatism

Blurred vision for near objects.

Symptoms of Astigmatism

The symptoms may vary depending on severity, but common signs include:

  • Blurred or distorted vision
  • Eye strain or discomfort
  • Frequent headaches
  • Difficulty seeing at night
  • Squinting to see clearly
  • Trouble focusing on fine details

In mild cases, symptoms may go unnoticed, making regular eye check-ups essential.

Causes of Astigmatism

Astigmatism occurs when the cornea or lens has uneven curvature, causing light rays to focus at multiple points instead of one.

Common Causes

  • Genetic (present from birth)
  • Eye injury or trauma
  • Previous eye surgery
  • Eye conditions like keratoconus
  • Age-related changes in eye structure

Risk Factors

You may have a higher risk of developing astigmatism if you:

  • Have a family history of refractive errors
  • Have undergone eye surgery
  • Suffer from corneal diseases
  • Have excessive eye rubbing habits

Diagnosis of Astigmatism

Astigmatism is diagnosed through a comprehensive eye examination by an ophthalmologist.

Common Tests Include

  • Visual acuity test
  • Refraction test
  • Keratometry (corneal curvature measurement)
  • Corneal topography

These tests help determine the exact power required for correction.

Treatment Options for Astigmatism

Astigmatism is highly treatable, and the goal is to improve vision clarity and comfort.

1. Eyeglasses

Customized lenses correct the uneven curvature of the eye.

2. Contact Lenses

Special toric lenses are designed for astigmatism correction.

3. LASIK Surgery

A permanent solution that reshapes the cornea using advanced laser technology.

4. SMILE / PRK Surgery

Advanced refractive procedures suitable for selected patients.

At ASG Eye Hospital, advanced diagnostic tools and experienced eye specialists ensure personalized treatment plans for every patient.

Complications if Left Untreated

Ignoring astigmatism can lead to:

  • Chronic headaches
  • Eye fatigue
  • Poor academic performance in children
  • Reduced quality of life

Early diagnosis helps prevent long-term vision issues.

Astigmatism in Children

Children often do not realize they have vision problems. Signs to watch:

  • Sitting too close to screens
  • Difficulty reading
  • Frequent eye rubbing
  • Poor school performance

Regular pediatric eye check-ups are crucial for early detection.

Prevention & Eye Care Tips

While astigmatism cannot always be prevented, you can protect your vision by:

  • Getting regular eye check-ups
  • Following the 20-20-20 rule (for screen use)
  • Wearing prescribed glasses or lenses
  • Avoiding eye strain and rubbing
