An incomplete or smaller cataract can occupy a focal region within the lens. During examination, the location of lens opacities is best determined using a slit beam to create an optic cross section, highlighting the anterior and posterior lens capsule with bright, convex and concave, respectively, lines of light, and then assessing relative depth and position of lesions. Cataracts may be capsular, cortical, or nuclear.
