Astigmatism is one of the most common vision problems, often occurring alongside nearsightedness or farsightedness. It happens when the cornea or lens of the eye has an irregular shape, causing light to scatter instead of focusing evenly on the retina. This leads to blurry, distorted, or double vision at all distances. While glasses and contact lenses can help, many patients are interested in lasting treatments that improve clarity and reduce dependence on corrective eyewear.
At Cornerstone Eye Associates, Dr. Claire Y. Chu provides advanced solutions for astigmatism. A board-certified ophthalmologist with a special interest in cataract and refractive surgery, Dr. Chu has built a reputation for combining precision, modern technology, and compassionate care. She has served as a clinical instructor at UT Southwestern for more than 15 years, been recognized on the D Magazine Best Doctors List, and continues to help patients in Dallas and Richardson achieve clear, comfortable vision.
What Is Astigmatism
Astigmatism occurs when the cornea or lens is not perfectly round, but shaped more like a football. This uneven curvature prevents light from focusing at a single point on the retina, resulting in blurred or distorted vision. People with astigmatism often notice difficulty seeing both near and far, along with eye strain, squinting, and headaches. Because the condition can develop gradually, many patients do not realize they have astigmatism until a comprehensive eye exam detects it.
Symptoms of Astigmatism
The effects of astigmatism can vary, but some of the most common symptoms include:
- Blurry or distorted vision at all distances
- Frequent eye strain or discomfort after reading or screen use
- Headaches related to prolonged visual tasks
- Difficulty with night vision or glare from headlights
- Squinting in an effort to see more clearly
These symptoms can interfere with work, hobbies, and driving, making treatment an important step toward better quality of life.
Treatment Options for Astigmatism
Astigmatism can be treated in several ways depending on its severity and whether it is combined with other refractive errors. Common options include:
- Glasses or Contact Lenses: The simplest form of correction, prescription lenses bend light properly to offset the irregular corneal shape. Toric contact lenses are specifically designed for astigmatism.
- LASIK Surgery: By reshaping the cornea with a laser, LASIK can permanently correct astigmatism, often eliminating or greatly reducing the need for glasses or contacts.
- Photorefractive Keratectomy (PRK): An alternative to LASIK for patients with thinner corneas or certain corneal conditions, PRK also reshapes the cornea to improve focus.
- Toric Intraocular Lenses (IOLs): For patients undergoing cataract surgery, toric IOLs provide long-term correction for astigmatism at the same time the cloudy lens is replaced.
At Cornerstone Eye Associates, Dr. Chu carefully evaluates each patient’s vision, lifestyle, and eye health before recommending the most effective treatment option.
