Mature Cataract

Clinical Features

  • Symptoms: usually severe decrease in vision.
  • Signs:
    • Total opacification of the lens capsule, cortex and the nucleus
    • May progress to hypermature cataract, which is characterized by wrinkling of the capsule due to liquefied lens cortex and Morgagnian cataract (sinking of lens nucleus inferiorly within the capsule)
    • May be complicated with phacolytic glaucoma.


  • Check pupils for relative afferent pupillary defect and retinal function assessment.
  • B-scan ultrasound study to rule out posterior segment pathologies.


  • Control of intraocular pressure if elevated
  • Surgical removal
