Keratoconus is an eye condition that affects the cornea, the transparent front layer of the eye. The cornea is responsible for focusing the light that enters the eye and allowing clear vision. Therefore, in keratoconus, the cornea bulges and progressively deforms, causing distortion of vision and a gradual loss of sight.

Causes That Cause It:

The exact cause of keratoconus is unknown, but it is believed to be associated with a combination of genetic and environmental factors. Some risk factors that may increase the likelihood of developing keratoconus include:

  • Family history of keratoconus
  • Frequent eye rubbing
  • Eye allergies
  • Certain medications, such as topical steroids
  • Autoimmune diseases

Symptomatology:

Symptoms can vary, and in this case, they may include, for example:

  • Blurred vision
  • Astigmatism
  • Difficulty seeing at night
  • Light sensitivity
  • Eye pain
  • Double vision
  • Halos or circles of light around lights
  • Difficulty wearing contact lenses

Keratoconus Treatment:

The treatment will depend on the severity of the condition. Therefore, in mild cases, glasses or special contact lenses may be prescribed to correct vision. However, in more severe cases, surgical treatment may be necessary.

  • Crosslinking: This procedure involves the use of UV-A rays and riboflavin (vitamin B2) to strengthen the corneal tissue and prevent its progression.
  • Intrastromal Rings: These small rings are implanted in the cornea to change its shape and improve vision.
  • Corneal Transplant: In more severe cases, when the cornea is severely damaged, a transplant may be necessary to restore vision.
