Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	phacoemulsification time	time spent for the phacoemulsification process was the phacoemulsification tip time (PTT) needed to divide the nucleus and the PTT needed to conquer it	intraoperative	No
Primary	effective phacoemulsification time	time in seconds required had 100% power been used throughout the phacoemulsification process documented for the separation of the nucleus (divide) and the aspiration of the quadrants (conquer)	intraoperativ	No
Primary	fluid volume	amount of BSS used for dividing and conquering	intraoperativ	No
Secondary	postoperative corneal oedema	central corneal thickness	1 day, 1 week, 6 months	No
Secondary	postoperative endotheial cell loss		6 months	No
