Astigmatism
Exploring Astigmatism: A Comprehensive Guide from Dr. Om Parkash Eye Institute
Welcome to Dr. Om Parkash Eye Institute, where your vision is our priority. In this detailed guide, we will delve into the world of astigmatism, shedding light on its definition, causes, symptoms, diagnosis, and the advanced treatment options available at our institute.
Understanding Astigmatism:
Astigmatism is a common refractive error that occurs when the cornea or lens has an irregular shape. Instead of being perfectly round or spherical, they have a more oval or oblong shape. This irregularity can cause light to focus on multiple points rather than a single point on the retina, resulting in blurred or distorted vision.
Key Aspects of Astigmatism:
Types of Astigmatism:
- Corneal Astigmatism: Irregular shape of the conea.
- Lenticular Astigmatism: Irregularities in the lens
Degrees of Astigmatism:
- Low Astigmatism: Up to 00 diopter.
- Moderate Astigmatism: 00 to 2.00 diopters.
- High Astigmatism: 00 diopters or more.
Causes of Astigmatism:
- Genetics: A family history of astigmatism increases the likelihood of developing this refractive
- Corneal Scarring: Injuries or diseases that cause scarring on the cornea can lead to astigmatism.
- Changes in the Shape of the Lens: Age-related changes or certain eye conditions can alter the shape of the lens, causing astigmatism.
Symptoms of Astigmatism:
- Blurred or Distorted Vision: Objects at any distance may appear blurry or
- Eye Strain: Prolonged periods of focusing on objects can cause discomfort or eye strain.
- Headaches: Astigmatism-related eye strain can lead to headaches, especially after prolonged visual tasks.
Diagnosis of Astigmatism:
Comprehensive Eye Examination:
- Visual acuity testing to assess the clarity of vision
- Refraction test to determine the degree and axis of astigmatism.
- Keratometry to measure the curvature of the cornea.
Corneal Topography:
- Mapping the surface of the cornea to detect irregularities contributing to
Autorefractors and Aberrometers:
- Automated instruments to provide additional data for a precise prescription.

Frequently Asked Questions about Astigmatism
Astigmatism is a common refractive error caused by irregularities in the shape of the cornea or lens. It results in blurred or distorted vision.
Yes, astigmatism can be classified into corneal astigmatism (related to the cornea) and lenticular astigmatism (related to the lens).
Astigmatism can be categorized as low, moderate, or high, based on the degree of refractive error measured in diopters.
Astigmatism can be caused by genetic factors, corneal scarring, and changes in the shape of the lens, among other factors.
Symptoms include blurred or distorted vision, eye strain, and headaches, especially after prolonged visual tasks
Astigmatism is diagnosed through a comprehensive eye examination, including visual acuity testing, refraction tests, keratometry, and corneal topography.
In a clinical survey of LASIK patients who had their corneal flaps created using a microkeratome in one eye and the IntraLase Method in the other, the vision in the IntraLase-treated eye was preferred 3-to-1 (among those who stated a preference.
Treatment options include prescription eyeglasses, toric contact lenses, and refractive surgeries like LASIK and PRK
Yes, toric contact lenses are specifically designed to correct astigmatism and are available in both soft and rigid gas permeable options.
These surgical procedures can provide a long-term solution for astigmatism by reshaping the cornea. However, individual results may vary.
The choice between eyeglasses and contact lenses depends on personal preferences, lifestyle, and the severity of astigmatism. An eye care professional can help make the right recommendation
The choice between eyeglasses and contact lenses depends on personal preferences, lifestyle, and the severity of astigmatism. An eye care professional can help make the right recommendation.
Music is played in the LASIK operating theater to create a pleasant experience for the patient. Patients are encouraged to bring their own music if they prefer
Yes, astigmatism in children can be corrected with eyeglasses or contact lenses. Regular eye check-ups are essential for early detection and management.
Yes, prescription eyeglasses and contact lenses are non-surgical options for managing astigmatism.
Regular eye check-ups are crucial for individuals with astigmatism. Your eye care professional can recommend the appropriate frequency based on your specific needs
Astigmatism can remain stable or change over time. Regular eye examinations help monitor any changes and adjust the prescription accordingly.
