Which cataract stage is described by the presence of refractile particles within the lens and a wrinkled anterior capsule?

• A. Hypermature cataract
• B. Mature cataract
• C. Immature cataract
• D. Nuclear cataract

Answer: (A)

Hypermature cataract is the stage where the cortical portion of the lens has liquefied and the capsule contracts, causing the anterior capsule to become wrinkled or corrugated. The breaking down of cortical material can produce refractile particles or droplets within the lens substance. This combination of a shrunken, wrinkled anterior capsule with internal refractile material reflects advanced degeneration of the lens compared with earlier stages. In immature cataracts you’d have partial opacification without this cortical liquefaction or capsule wrinkling; in a mature cataract the lens is fully opacified but without significant liquefaction or capsule distortion; and nuclear cataracts center on changes within the nucleus, not the cortex with liquefaction.
