What is Keratoconus?
Several people have the habit of rubbing their eyes whether it be due to allergies, dry eyes , or just irritation in general. Eye rubbing may seem harmless since it provides some soothing sensation, like scratching an itch. However, rubbing your eyes can cause more damage than you think.
Keratoconus has been associated with eye rubbing and is a degenerative eye disease that leads to structural changes within the corneal tissue. This progressive condition results in the thinning and weakening of the cornea, which eventually causes it to deform and adapt a cone-like shape. When the cornea's shape has altered enough, it fails to allow light to focus properly on the retina and therefore impairs vision. In its more advanced stages, keratoconus could result in irreversible corneal deterioration.
Symptoms of keratoconus include:
Blurred or distorted vision
Inability to see in dim light
The treatment of keratoconus is to stabilize the condition and prevent further progression into corneal transplantation. For most patients, once the keratoconus is stabilized, optimal vision is achieved with specialty contact lenses.
