Cystotome-assisted prechop technique.

UNLABELLED: We describe a manual prechop technique to divide the nucleus using a cystotome. In the cystotome-assisted prechop technique, after the capsulorhexis, the surgeon-bent cystotome is inserted into the lens while the Nagahara chopper is set around the lens equator. The cystotome and the chopper are then brought together in the center to create a bisecting crack in the nucleus, dividing it cleanly into 2 hemispheres.
