Astigmatism is a refractive error, which means that as light enters your eye, it’s distorted and doesn’t focus correctly on your retina. Unlike myopia (nearsightedness) and hyperopia (farsightedness), astigmatism affects both your near and distance vision.
In addition to causing blurry vision, astigmatism also causes headaches and eyestrain. While patients of all ages can have astigmatism, it usually develops in childhood. If your child complains of headaches, rubs their eyes frequently, and has a declining academic performance, you should schedule a comprehensive eye exam.
Astigmatism is usually due to irregularly shaped corneas. A healthy eyeball is a sphere, and your cornea is a clear dome that covers it. If you have astigmatism, your cornea is shaped more like a football than a soccer ball. This bends light as it enters your eye and prevents it from focusing on the correct part of your retina for clear vision.
It’s also possible for an irregularly shaped intraocular lens to cause astigmatism, although this is less common than an abnormal cornea.
While doctors don’t fully understand what causes astigmatism, your risk of having astigmatism is higher if a family member also has it. You may also develop astigmatism after an eye injury, eye disease, or eye surgery. Your condition may get worse if you read in low light or sit too close to the television.
At Envision Eyecare, Dr. Fuzyalov diagnoses astigmatism during a comprehensive eye exam. In addition to visual acuity tests that measure the clarity of your vision, he also uses devices such as a keratometer to measure the curve of your cornea and a slit lamp to study the structures of your eye.
In most cases, Dr. Fuzyalov can correct astigmatism with corrective lenses. If you prefer to wear contact lenses, he may suggest gas permeable or hybrid lenses to provide clear vision. You may also benefit from toric contact lenses, which are slightly weighted to control their position on your eyes.
You can also talk to Dr. Fuzyalov about LASIK or other refractive surgery options to address astigmatism.
