Comparison of Two Phacoemulsification-methods: Low Fluidic EasyTip 2.2mm vs. High Fluidic EasyTip 2.2mm

April 9, 2015 updated by: Rupert Menapace, Medical University of Vienna
The aim of this study was to compare the intraoperative efficiency, safety and postoperative outcomes of cataract surgery with two different "high-fluidic" settings.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: HF easyTip 2.2mm
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
Other: LF easyTip 2.2mm
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 20ml/min, vacuum 400 mmHg, bottle height 100cm.
Procedure: cataract surgery

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
phacoemulsification time
Time Frame: intraoperative
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 Frame: intraoperative
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
Time Frame: intraoperative
amount of BSS used for dividing and conquering
intraoperative

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
postoperative corneal oedema
Time Frame: 1 day, 1 week, 6 months
central corneal thickness
1 day, 1 week, 6 months
postoperative endotheial cell loss
Time Frame: 6 months
6 months
