When Contact Lenses Cause Scarring

Did you know that a corneal ulcer can cause permanent scarring?

At the front of the eye is a clear layer of tissue called the cornea. The cornea allows light to enter the eye.  The cornea is bathed in tears, which provide the natural defense against bacteria and viruses.

A corneal ulcer is an open sore that forms on the cornea, usually caused by infections.  Wearing contact lenses too long or while sleeping, can lead to these infrections.

People who wear expired soft contact lenses, wear disposable contact lenses, or sleep in contact lenses, are at an increased risk for developing corneal ulcers.

Corneal ulcers must be treated aggressively with strong antibiotics.  Symptoms of a corneal ulcer include:

  • itchy eye
  • watery eye
  • pus or eye discharge
  • burning or stinging sensation in the eye
  • red or pink eye
  • sensitivity to light
  • eye inflammation
  • sore eye
  • excessive tearing
  • blurred vision
  • white spot on your cornea
  • swollen eyelids
  • pus or eye discharge
  • sensitivity to light
  • feeling like something is in your eye
