The cornea is the outer, clear, round structure that covers the
colored part of the eye (iris) and the pupil. The cornea directs light rays
into the eye and helps focus them on the light-sensitive retina at the back of
the eye, providing sharp, clear vision.
Vision problems such as astigmatism or nearsightedness (myopia) are often caused by changes in the normal shape of the cornea.
