Brief Summary

The aim of this study was to compare the intraoperative efficiency, safety and postoperative outcomes of cataract surgery with two different "high-fluidic" settings.

Efficacy and Safety

Outcome Measures

Primary Outcomes (3)

• 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

Secondary Outcomes (2)

• postoperative corneal oedema

  1 day, 1 week, 6 months

• postoperative endotheial cell loss

  6 months

Study Arms (2)

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.

Procedure: cataract surgery

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.

Procedure: cataract surgery
