Cornea, Lens, and Iris. The iris is the colored part of the eye. A circular muscle in the iris controls the amount of light entering the eye through the pupil, the black area in the center of the iris. The cornea is the outer clear, round structure that covers the 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. The lens is located behind the iris and is normally clear. Light passes through the pupil to the lens.
The cornea is the transparent front part of the eye that covers the iris, pupil and anterior chamber. The surgical procedure is performed by ophthalmologists, physicians who specialize in eyes, and is often done on an outpatient basis.
