| Label | Type | Description | Intervention Names |
|---|---|---|---|
| HF easyTip 2.2mm | Other | 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. |
|
| HF easyTip 2.8mm | Other | The phacoemulsifications tip used was the easyTip 2.8mm 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 50ml/min, vacuum 600 mmHg, bottle height 100cm. |

| 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 |
| 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) | intraoperative |
| fluid volume | amount of BSS used for dividing and conquering | intraoperative |
