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 and the chopper was placed beyond the edge of the nucleus and moved to the phaco tip horizontally (a, b). The phaco tip was placed in the centre of 2 hemispheres using only irrigation and the chopper was placed beyond the hemisphere (c, d)
