The doctors at Eye Physicians of Northampton specialize in treatment of keratoconus with CLs, corneal transplantation and Corneal Collagen Crosslinking (CXL)

Keratoconus is an abnormal shape of the cornea. Keratoconus literally means “cone-shaped cornea.” Keratoconus is an uncommon eye condition where the normally round, oval-like cornea becomes thin and develops a cone-like bulge.


The cornea is the clear, front part of the eye, that has a lot to do with how you see. As light enters the eye, the shape of the cornea direct the light rays so that they land in a particular fashion on the nerves in the back of the eye, called the “retina.” If the light rays are directed correctly, you can see clearly. When the cornea is affected by keratoconus, it expands outward and becomes extremely steep and almost pointed, thus changing the direction of light entering the eye. Images become blurry and distorted. Keratoconus can make many activities such as skiing, driving, typing on a computer and watching television, difficult.

Symptoms Of Keratoconus

Keratoconus is routinely problematic in both eyes, however; symptoms in each eye may differ. Keratoconus can affect persons of all ages but typically starts to develop by the mid – late teen years. The rate of keratoconus progression varies. It will often progress slowly for 10 to 20 years and then suddenly stop.

Most common symptoms include:

  • distortion of vision
  • sensitivity to light
  • glare
  • slight irritation
  • mild blurring of vision
