Before we discuss the procedure, it is important for you to understand the parts of your eye involved with sight. These structures include the cornea, iris, pupil, lens and retina.
Your cornea is a thin, clear layer on the outside of your eye. The iris, or the colored part of your eye, is a muscle that controls the amount of light going through your pupil, or the round opening in the center of your eye. Behind the iris, sits the lens, which is just larger than your pupil. It is enclosed by a thin, clear capsule that holds the lens in its proper place.
When light enters your eye, the cornea and lens form the light rays into a beam of light that is focused directly onto your retina, where images are created.
This image is then sent from the retina, through your optic nerve, to your brain for further processing.
