There argon 2 major vitrines of ECCE: manual expression, in which the lens is removed through an incision made in the cornea or the sclera of the eye; and phacoemulsification, in which the lens is broken into fragments inside the space capsule by ultrasound energy and removed by aspiration.

Nuclear cataracts are most usually associated with age and with smoke as risk factors. Cortical cataracts. Cataracts in the cortex of the lens develop more cursorily than nuclear cataracts but ! run softer and are easier to remove. They are thought to be caused by an profit in the water content of the lens. chance factors for cortical cataracts embroil female sex and African or Caribbean heritage.
