The phacoemulsifications tip used was the easyTip 2.2mm tip (Oertli Instruments, Berneck, Switzerland). The cristaline lens was divided into four quadrants using an aspiration flow rate of 10ml/min and vacuum of 70 mmHg. The quadrants were aspirated using the following linear power and fluidic settings: aspiration flow rate 45ml/min, vacuum 600 mmHg, bottle height 100cm.

The cristaline lens was divided into four quadrants using an aspiration flow rate of 10ml/min and vacuum of 70 mmHg. The quadrants were aspirated using the following linear power and fluidic settings: aspiration flow rate 20ml/min, vacuum 400 mmHg, bottle height 100cm.

time spent for the phacoemulsification process was the phacoemulsification tip time (PTT) needed to divide the nucleus and the PTT needed to conquer it

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)
