Abstract Details


To compare the intraoperative performance and postoperative outcome after microcoaxial torsional phacoemulsification using different torsional energy modalities (continous, pulse and burst).


SBU kayseri Training and Research Hospital Department of ophthalmology Kayseri Turkey


Cataracts were treated using 2.2 mm microcoaxial torsional phacoemulsification using different phacoemulsification energy modalities with a 45 degree the balanced phaco tip. Intraoperative measurements included total ultrasound (US) time, cumulative dissipated energy (CDE), torsional US time, and balanced salt solution (BSS) use. The central endothelial cell density (ECD) and central corneal thickness (CCT) were evaluated preoperatively and postoperatively 1, and 30d after surgery using noncontact specular microscopy.


The 276 enrolled eyes (260 patients) were divided equally among the 3 different energy modalities ( continuous, pulse, and burst modes). Intraoperative measurements showed significant differences in total US time, torsional US time, CDE, and BSS use among groups (P<0.05).


Torsional phacoemulsification performed with continous mode provided more effective lens removal in all cataract grades.
