Astigmatism

Many people have never heard of astigmatism, although it is an extremely common eye condition.

Astigmatism is one type of refractive error. Nearsightedness and farsightedness are other types of refractive error. Refractive errors are not eye diseases. Refractive error is a result of and imperfection of the size and shape of the eye, which results in blurry or double vision.

If left untreated, astigmatism may cause eyestrain, headaches, and blurry vision. If you have astigmatism you may not see objects in the distance or near without some form of distortion.

Symptoms of Astigmatism

Small amounts of astigmatism can go unnoticed, however, you may be suffering from eye fatigue, eyestrain, and headaches.

Astigmatism is a condition that usually can develops early in childhood. According to a study from The Ohio State University School of Optometry, 28% of school age children suffer from astigmatism. Parents should be aware that their children might not notice that their vision is blurry, not understanding that this is not normal. Nevertheless, astigmatism should be treated because vision problems can lead to learning problems and in extracurricular activities. Make sure to have your child’s eyes examined at an eye doctor’s office at least once a year.

Causes of Astigmatism

Astigmatism is generally caused by a cornea with an irregular shape. The cornea is the front, clear layer of the eye. With astigmatism, the cornea is not round and spherical and is instead irregular having two curves instead of one curve. Astigmatism in some cases could also be caused by the lens located inside the eye that is irregular in shape.

Eyes with astigmatism distort the light that comes into the eyes because the cornea is irregularly shaped. This causes the light rays entering the eye to create two images in the back of the eye (because of the two curves), instead of one image. This is what causes the distortion in sight.

Treatments for Astigmatism

For most people, their astigmatism is fully corrected using prescription glasses or contact lenses. If you select contact lenses to correct your vision, soft contact lenses are the most common option. If for whatever reason soft contact lenses are not an option, rigid gas permeable (RGP or GP) are also a great choice. Rigid gas permeable lenses usually give the clearest vision but the adaptation process will be significantly longer. Another option are hybrid contact lenses. These contacts have a center made from a rigid gas permeable (RGP) lens and an outer ring made of soft contact lens material. This type of lens provides both excellent clarity and comfort. LASIK could be another option to correct astigmatism. LASIK usually only corrects low levels of astigmatism and some patients with higher levels of astigmatism might not be candidates.

As of Tuesday evening, March 17th, the CDC has recommended that all routine eye care be deferred until further notice, in order to slow the transmission of COVID-19 through our community. We will follow their recommendations and close our office to regular eye exams until further notice.

Please be assured that we are still available to triage all urgent and emergent issues as well as help you with routine matters during this challenging time.

What does this mean?

1) If you are scheduled for an annual eye examination our office will contact you to reschedule
2) If you need to replace glasses or contact lenses and need an extension on your prescription, please contact us and we will assist you in obtaining some until you can come in for a visit.
3) If you are running out of medication please contact us and we can transmit a refill electronically to your pharmacy.
4) If you have an ocular emergency we are, as always, available to help you at any time. Call us at 970-221-4811.
5) If you have an issue that cannot wait for an office visit, contact us and we will schedule a FaceTime, Skype or telephone appointment with one of our doctors. Medicare has temporarily relaxed its telehealth rules to allow this type of communication during the pandemic crisis. Other insurers may follow suit and allow for reimbursement of virtual care costs. The consultation must be initiated at your request.
6) During this period of social distancing and quarantine, we must all do our part by restricting activities outside the home except for getting medical care. Do not go to work, school, or public areas. Avoid using public transportation, ride-sharing, or taxis.
7) Please remember that 80% of COVID-19 cases are mild and resolve within a week. However, if you feel your symptoms are worsening, call ahead before visiting your doctor’s office or emergency department and tell them you have or may have COVID-19. This will help the office protect themselves and other patients.

The CDC has many wonderful resources. Arming yourself and your family with clear information will help you avoid undue stress.https://www.cdc.gov/coronavirus/2019-ncov/prepare/prevention.html https://www.cdc.gov/coronavirus/2019-ncov/prepare/managing-stress-anxiety.html

We have asked our staff to stay home until further notice to protect them, our patients, our city, our nation, and our planet. Despite the financial and emotional hardships this will cause, we ask every one of you to do the same.

Together we will weather this storm.

With sincerest wishes for your continued good health, we remain at your service,
