Abstract Details

Purpose:

To compare the intraoperative performance and postoperative outcome after microcoaxial torsional phacoemulsification using either active or passive (gravity based) fludic systems.

Setting:

SBU kayseri Training and Research Hospital Department of ophthalmology Kayseri Turkey

Methods:

Cataracts were treated using 2.2 mm microcoaxial torsional phacoemulsification using either active or passive (gravity based) fludic system with a 45 degree mini flared Kelman 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, 7, and 30d after surgery using noncontact specular microscopy.

Results:

The 102 enrolled eyes (102 patients) were divided equally between the active and passive fludic systems. Intraoperative measurements showed significantly less total US time, torsional US time, CDE, and BSS use in the active group than in passive group (P<0.05).

Conclusions:

Torsional phacoemulsification performed with a active system provided more effective lens removal with less total US time, torsional time, CDE, and BSS use, as well as less changes in ECD with passive system in all cataract grades. The active system provides more efficient than gravity system.
