Brief Review of Lens Anatomy and Clinically Relevant Landmarks

  1. Clinically distinguishable zones (see Amos, Chapter 19, page 607)

  2. Documenting lens changes

    One way to document lens changes is to provide a diagram. Two common diagram types can be used:

    A frontal view shows the cataract extent relative to the visual axis







    A cross-sectional diagram is used to designate gradings, which are usually localized grossly to the adult nucleus and/or cortex. The cross-section corresponds to a parallelepiped or optic section view
