Keratoconus Treatment With Our
Bixby, Okmulgee, and South Tulsa Optometrist
Keratoconus is a condition that occurs when a patient's cornea is not round as it should be, but extends out in a cone shape. This happens when the framework of the cornea is not strong enough to hold the proper shape. This makes it very difficult for the eye to be able to focus when not wearing glasses or contact lenses. Speak with our doctor of optometry at one of our The Eye Center locations in South Tulsa or Okmulgee to find out more about this condition and treatment options.
What Causes Keratoconus?
This condition occurs when there is a decrease in antioxidants that are located in the cornea. Antioxidants normally protect the collagen fibers that keep the cornea in place. Weakened fibers cannot hold the proper shape of the cornea and it therefore becomes cone shaped.
Keratoconus can happen quickly or slowly come on over several years. It often runs in families and usually begins when a person is a teenager. It can occur, but is less common, in children and those in their 20's. It rarely occurs in people 40 and over.
How Will a Doctor of Optometry Diagnose Keratoconus?
An optometrist should notice the symptoms of keratoconus during a regular eye exam. This condition changes vision by causing irregular astigmatism and for vision to become nearsighted. Be sure to mention any symptoms to your doctor during the exam. Symptoms include blurry night vision, a sudden change in vision, double vision, objects looking distorted, seeing halos around bright lights, lights that appear to be streaking, and seeing ghost images.
For an optometrist to be sure that a patient has keratoconus, they will need to take a look at the shape of the cornea. This can be done in a few ways, the most common of which is called cornea topography. This takes a picture of the cornea and analyzes the shape. If this condition runs in the family, it is important to have this done every year.
How Would a Doctor of Optometry Treat Keratoconus?
Treatment normally includes eyeglasses or contact lenses. These can often make vision clear again. However, in some cases, cornea collagen crosslinking, a laser procedure known as PTK, or a cornea transplant may be needed.
