From: Comparison of power-free-chop and phaco-chop techniques for moderate nuclei
The procedure of power-free-chop technique. The phaco tip was leaned near the geometric centre of the nucleus as deep as possible (a). The nucleus was split into 2 hemispheres by the encountered chopper and phaco tip (b). The phaco tip was placed in the centre of 2 hemispheres using only irrigation and the chopper was placed beyond the hemisphere (c). The chopper moved to the phaco tip horizontally to split the hemisphere into 2 pieces (d)
