Complications could include:
The cornea is a thin, transparent dome that covers your eye's iris and pupil. The iris is the colored part of your eye, and the pupil is the black center. All light that enters your eye and allows you to see strikes your cornea first.
A corneal ulcer is an open sore that forms on the cornea. It's usually caused by an infection. Even small injuries to the eye can lead to infections.
