Myths About Keratoconus

Published on
June 30, 2021

Keratoconus is an eye disorder that causes the cornea to become thinner and more cone shaped. The cornea is the clear layer that covers the front of the eye and contributes greatly to how we see. This corneal disorder causes a lot of visual disturbances due to the progressive thinning and change in shape of the cornea.

If you’ve been diagnosed with keratoconus, there could be a lot of new information to take in which may be confusing. We’d like to debunk some common myths about keratoconus.

Keratoconus is only diagnosed in young people

Age is not a risk factor and anyone can develop keratoconus at any age. It is most common for people to develop keratoconus in their teens and it often continues progressing into the thirties.

Keratoconus causes blindness

This corneal disorder can cause significant visual impairment, and there are cases where it could lead to blindness. However, that being said, keratoconus does not automatically cause blindness and many people with this condition are able to still see, using various optical corrections such as contact lenses or surgical procedures. If keratoconus progresses to the point where there is excessive corneal scarring and the patient can no longer tolerate contact lenses, then there may be a need for a corneal transplant.

The only treatment for keratoconus is corneal transplant

Corneal transplants are the very last resort for extreme cases when no other methods of treatment are sustainable. There are many other effective methods that are used prior to the last option of a transplant. There are a variety of contact lenses ranging from soft lenses to sclerals which allow people with keratoconus to see more clearly. In addition, there are successful procedures such as cross-linking and conductive keratoplasty.

Cross linking cannot be performed over age 40

Age is not a contraindication for this surgery, and therefore it can be performed on patients over age forty. Each individual patient needs to be checked if they are an eligible candidate for this procedure. Cross linking is a minimally invasive method which uses ultraviolet light and eye drops to strengthen the fibers in the cornea. This surgery is the only method that prevents progressive keratoconus from getting worse, as it stabilizes the cornea and slows down the bulging. It has been reported to have a 95% success rate.

Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.

I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.

Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.

Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.

Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.
