DEFINITION of cataracts

They develop slowly with age, trauma, radiation, or diseases like diabetes, leading to blindness if untreated; surgery replaces the lens with an artificial one, restoring sight effectively.

  • Nuclear sclerotic: Central lens hardening.
  • Cortical: Wedge-like opacities.
  • Posterior subcapsular: Back lens clouding, glare-prone.
  • Phacoemulsification: Ultrasonic lens removal surgery.
  • Glaucoma: Often co-occurs, pressure-related damage.

ETYMOLOGY of cataracts

latin From Latin “cataracta” (waterfall, portcullis), from Greek “katarrhaktēs” (down-rushing), metaphorically describing the white opacity resembling rushing water or an obstruction.
