Keratoconus is a condition of the eye that affects the shape of your cornea. A healthy cornea is round and shaped like a dome. If you have keratoconus, your cornea will gradually bulge out into the shape of a cone. If you have this condition or suspect that you do, there are a few things that you should know.
Q: Who Is at Risk Of Developing Keratoconus?
A: Doctors don't know what causes this condition; however, there are a few factors that put you at greater risk.
- Family history
- Frequent rubbing of the eye
- Down syndrome
- Ehlers-Danlos syndrome
- Hay fever
- Retinitis pigmentosa
Q: What Are the Symptoms of Keratoconus?
A: In the early stages of this condition, you may not experience any symptoms. The signs and symptoms may change as the disease progresses. The symptoms include:
- Blurry vision
- Distorted vision
- Sensitivity to bright light and glare
- Difficult seeing at night
- Sudden worsening of the vision
- Cloudy vision
- Frequent changes in your eyeglass prescription
Q: How is Keratoconus Diagnosed?
A: There are a few tests that your eye doctor will perform to diagnose this condition.
- Slit-lamp exam: Your optometrist will use a low-powered microscope to view your eye. They will evaluate the shape of the cornea to check for abnormalities.
- Keratometry: During this test, your optometrist would focus a circle of light on your cornea. This allows them to measure the reflection to determine the shape of your cornea.
- Computerized corneal mapping: This test can create a detailed shape map of the surface of your cornea. It also measures its thickness.
Q: How Is Keratoconus Treated?
A: There are several treatment methods for this condition. The treatment that your optometrist will recommend would determine on your eyes and the severity of your condition.
- New prescription: In the early stages of the condition, your eye doctor can give you a new eyeglass or contact lens prescription to correct the blurry or distorted vision.
- Gas permeable lenses: Gas permeable lenses are rigid and hold their shape. This makes it possible for them to keep the round shape of your eye.
- Piggyback lenses: If you find that gas permeable lenses are uncomfortable, piggyback lenses can help. This is where you put a soft pair of lenses under the gas permeable lens to act as a cushion.
- Corneal Inserts: This is a surgical procedure where your doctor would place a clear, plastic insert that is designed to flatten the cone shape of your corneas.
