[Aquadiassectio alia post aliam. A helpful technique in the fractionated preparation of the lens nucleus in extracapsular cataract extraction].
The surgical step in separating the lens nucleus from the lens cortex is frequently the most traumatizing moment. The trick in multiple aqua dissection permits severance of the lens nucleus from the lens cortex and the lens cortex from the capsule in precisely defined planes under completely controlled conditions, retaining the advantages of the closed system. Penetration of the separating fluid front can be recognized well in advance of the red light reflex. The segregation lines are shown in the drawing in an intensified, annularly arranged red light reflex, which is realized in the concentrically stratified structure of the lens. In phacoemulsification it is thus possible to remove the inner nucleus first and separately. The posterior capsule can then be well protected by a thicker cushion of cortex. Multiple fractionated hydrodissection - aquadissection alia post aliam - is not only a good example of substantial reduction in surgical trauma, but allows good control in the bag phacoemulsification.
