Some surgeons love the pre-chopper because it allows for efficient splitting of a nucleus, usually into quadrants. This surgeon takes it a step further and divides each of these quadrants in half, thereby creating 8 pieces of nucleus. Each of these eighths is then phaco-aspriated using just the phaco probe and no second instrument. In fact there is only one incision in this eye as the non-dominant hand is not as active in this technique. Clearly this technique is efficient in the hands of our guest surgeon. Have you tried the pre-chopper? Please let us know.
