title: Nucleus removal in planned extracapsular cataract extraction. A new instrument.
abstract: A new technique of nucleus delivery is discussed. The plane between nucleus and cortex is defined and expanded under direct visualization using hydraulic dissection via a new instrument. The nucleus is irrigated out of the eye or the instrument can be directed into the already defined cleavage plane to effect mechanical extraction via the barb on its superior surface. This technique ensures minimal trauma to zonules and corneal endothelium and results in concomitant removal of a large quantity of cortical material, which simplifies the process of cortical cleanup.
