Extracapsular cataract extraction (ECCE) is a category of middle mental process in which the lens of the eye is outside while the stretchable contraction that covers the lens is left partially intact to forgo nidation of an intraocular lens (IOL). This approach is contrasted with intracapsular cataract extraction (ICCE), an older procedure in which the surgeon removed the complete lens deep down its capsulize and left the eye aphakic (without a lens). The patients mountain was right after intracapsular extraction by extremely thickheaded specs or by contact lenses. There are 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 capsulate by ultrasound e nergy and removed by aspiration. Ophthalmologists split up cataracts consort to their location in the lens. It is possible for a someone to turn out more than one type of cataract. atomic cataracts.

Nuclear cataracts are most ordinarily associated with age and with smoke as risk factors. Cortical cataracts. Cataracts in the cortex of the lens develop more cursorily than atomic catarac! ts but run softer and are easier to remove. They are thought to be caused by an profit in the water content of the lens. try 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, is the softest and most rapidly growing type.
