Astigmatism occurs when the cornea or lens is irregularly shaped, preventing light from focusing evenly on the retina. It is diagnosed through a comprehensive eye exam using tools that measure the eye’s curvature and refractive error.

Condition
Astigmatism
Astigmatism is a refractive error that occurs due to the shape of the eye’s cornea or lens. It is a common condition that causes patients to experience blurred or distorted vision at both near and far distances.
At CODET Vision Institute, we provide laser eye surgery for astigmatism, which is one of the most effective forms of corrective eye surgery available today.
An Overview: Astigmatism
At a Glance:
- Creates blurry or distorted vision at all distances
- Caused by an irregular curvature of the cornea
- May occur alongside myopia or hyperopia
- Without treatment, astigmatism can cause uncomfortable symptoms such as eyestrain or discomfort, and headaches.
Astigmatism is an imperfection in the curvature of the cornea or lens. This imperfection prevents light that enters the eye from refracting on the retina properly. As a result of this improper refraction, vision is blurred or distorted.
Both close and distant objects appear blurry or distorted to people with astigmatism, but the greater the astigmatism a person has, the blurrier their vision.
People with mild astigmatism may be bothered by slight blurring or distorted vision regardless of distance, but people with severe astigmatism can have their vision affected so much that it prevents them from performing their daily activities.
Astigmatism Symptoms May Include:
- Blurry vision or areas of distorted vision
- Eyestrain
- Headache
- Squinting to try to see clearly
- Eye discomfort
Astigmatism Treatment
Astigmatism is easily diagnosed by ophthalmologists. Treatments for astigmatism change the way that light rays are bent when they enter the eye so that they come into a point of focus precisely on the retina.
When astigmatism causes objects to appear blurred or distorted, proper treatment can restore clear vision and make daily activities easier. Depending on the severity of the condition, options can range from glasses to laser eye surgery for astigmatism.
Treatment options include:
- Prescription glasses or contact lenses: These wearable tools compensate for the eye’s inability to focus.
- All-Laser-LASIK and PRK: These are forms of corrective eye surgery for astigmatism that utilize lasers to reshape the cornea, changing the way it bends entering light rays.
- Refractive Lens Exchange with Premium IOLs: This eye treatment for astigmatism involves implanting an intraocular lens inside the eye. There are a number of astigmatism-correcting IOLs available in the market. AT CODET Vision Institute, we focus on three different types of astigmatism-correcting IOLs:
- Standard Toric IOL – corrects astigmatism and aims to provide spectacle-free vision for distance vision.
- PanOptix Toric IOL – corrects astigmatism and aims to provide spectacle-free vision for distance, intermediate, and near vision.
- Light Adjustable Lens (LAL) – the LAL involves conventional intraocular lens implantation surgery, while allowing the surgeon to adjust the power of the IOL after the surgery has taken place. This allows the surgeon to correct astigmatism, aims to provide optimal vision at distance, intermediate, and near ranges. Additionally, the LAL typically produces glare and halo-free vision after surgery.
- Implantable Collamer Lens (ICL): This astigmatism treatment is reserved for patients with high degrees of Astigmatism or those who are not candidates for refractive surgery.
