Diagnosis and treatments to slow and prevent vision loss, or referrals to ophthalmologists as needed.
Astigmatism, the term for an eye that isn’t perfectly round, is one of the most common causes of blurry vision. At Stonebrook Eyecare and Eyewear in Frisco, Texas, therapeutic optometrist Katherine Egan, OD, diagnoses astigmatism and writes prescriptions for eyeglasses and contact lenses. She can also provide referrals and pre- and postoperative care for laser surgery. Schedule an appointment over the phone.
Astigmatism is one of the most common refractive errors. Other refractive errors include nearsightedness and farsightedness. Refractive errors are defined by blurry uncorrected vision because your eyes have difficulty focusing light properly on their own.
Astigmatism isn’t a disease or a problem with your eye health, but it does usually mean you need vision correction to see clearly, such as glasses, contact lenses, or laser eye surgery.
If you have astigmatism, your eyes have an irregular shape (closer to an egg than a ball). As a result, your eye bends light unevenly, so your vision is blurry at any distance. By contrast, eyes without astigmatism bend light evenly and allow for clear, uncorrected vision.
Most people have some degree of astigmatism. It’s highly unusual for your eyes to be perfectly round. Astigmatism is only a problem if it’s significant enough that you can’t see clearly without vision correction.
In addition to blurry vision, uncorrected astigmatism can cause headaches and eye discomfort. Schedule an appointment with Dr. Egan if you have any concerns about your ability to see.
Astigmatism is natural, and most people who have it are born with it. Many children are diagnosed with astigmatism after they have difficulties reading and concentrating in school. It’s common for school-age children who simply need glasses to be misdiagnosed with a learning or behavioral disorder.
Usually, children grow and develop, their astigmatism gets worse, and they frequently need stronger corrective lens prescriptions. It usually stabilizes around age 20.
When you have an eye exam with Dr. Egan, she tests you for refractive errors. She determines if you have astigmatism and writes prescriptions for corrective lenses, either glasses or contacts. She recommends glasses and contacts that fit your eye care needs.
Glasses and contacts allow you to see clearly, though they don’t cause any permanent change to your astigmatism. Many adults simply choose to wear contact lenses.
If you’d like to correct your astigmatism, you may choose to undergo laser eye surgery, also known as LASIK. LASIK is a quick, safe, popular procedure that reshapes your eyes and allows you to see clearly without glasses or contacts. Dr. Egan provides referrals to trusted local ophthalmologists and pre- and postoperative care for LASIK.
