What is the Condition?

Keratoconus is an eye disease that affects the shape of the cornea. The cornea maintains its round shape with the help of tiny fibers known as collagen. It is when these fibers become weak that the cornea assumes a cone-like shape, which ends up leading to hazy vision. Keratoconus usually takes place due to the lack of antioxidants in the eye that are able to rid the cornea cells of dangerous by-products.

How does it Affect the Eye?

This condition causes the cornea to thin and become a cone-like shape, which deflects light as it hits the retina. As a result, the patient has blurry vision.

What are the Symptoms of this Condition?

The symptoms of keratoconus include:


  • Glare
  • Sudden and recurrent changes in prescriptions for glasses
  • Bright lights look as if they have a halo around them
  • Sensitivity to light
  • Having a blurry vision
  • Irritation of the eye(s)
What are the Risk Factors for Developing this Condition?

Some of the risk factors for keratoconus are:

  • If you are suffering from the condition and find yourself constantly rubbing your eyes, you may aggravate the situation
  • This is a hereditary disease
How is this Condition Treated?

During the early stages of keratoconus, the patient could overcome the problem and see better with the help of prescribed glasses or contact lenses. However, if the condition progresses, you may need to shift to other options, such as:

  • Custom soft contact lenses
  • Hybrid contact lenses
  • Scleral lenses
Topography-Guided Conductive Keratoplasty:

This procedure will help smooth out any irregularities on the surface of the cornea.

Gas Permeable Contact Lenses:

If soft contact lenses do not do the trick, this type of lens is the preferred treatment.

Corneal Crosslinking:

This prevents the progression of the condition by strengthening the tissues of the cornea.


These are implants that are placed right under the cornea to help decrease the thinning, in turn fixing the patient’s vision.


Also known as Phototherapeutic Keratectomy, PTK improves the comfort of the lens by smoothing out the scars.

Corneal Transplant:

This is usually done as a last resort. If your condition becomes severe, the doctor will recommend a corneal transplant. In the procedure, your cornea will be taken out and replaced with a donor cornea. A patient may need to wear contact lenses after this surgery.
