Cornea infection (keratitis, corneal ulcer) often comes from an improper use of contact lenses and requires great attention.

If not treated immediately, it can result in corneal scars that limit vision.

When patients have red eyes and wear contact lenses, it is necessary to suppose the existence of a corneal infection, and therefore stop using contact lenses and ask an ophthalmologist.

In case of corneal scars, it can be treated with a laser technique known as PTK; if the cornea is too damaged, a transplant could be the solution.
