GRADE LEVELS: 9-12
TIME ALLOTMENT: Two to three 45-minute class periods
In this media-enhanced lesson, students will learn about the history and state-of-the-art of one of the world’s most commonly performed surgical procedures—eye cataract removal and replacement. Using clips from the public television documentary Through My Eyes: The Charlie Kelman Story—a biography of one of the ophthalmologists most directly responsible for developing the modern surgery used to treat cataracts—this lesson traces the scientific progression from primitive “couching” treatments in antiquity to the modern use of phacoemulsification and foldable intraocular lenses in the present day. This lesson is recommended for use with students who have recently completed a unit on the anatomy of the eye.
