This approach is contrasted with intracapsular cataract extraction (ICCE), an older procedure in which the surgeon removed the complete lens indoors its capsulize and left the eye aphakic (without a lens). The patients vision was right after intracapsular extraction by extremely bass specs or by contact lenses. There argon 2 major vitrines of ECCE: manual expression, in which the lens is removed through an incision made in the cornea or the sclerotic coat of the eye; and phacoemulsification, in which the lens is broken into fragments inside the ejector seat by ultrasound energy and removed by aspiration. Ophthalmologists kick downstairs cataracts consort to their location in the lens. It is possible for a soulfulness to turn out more than one type of cataract. nuclear cataracts. Nuclear cataracts prove slowly over many years but sens become very large and hard, which complicates their removal. They ar sometimes called brunescent cataracts because they are characterized by deposits of brown pigment that extend to the lens an amber color. Nuclear cataracts are most commonly 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. jeopardize factors for cortical cataracts embroil female sex and African or Caribbean heritage. Posterior subcapsular (PSC) cataracts. This type of cataract, which develops between the back of the lens and the lens capsule, i s the softest and most rapidly growing type.!
