Abstract Details

Purpose:

To describe the opportunities that torsional U/S combined with the new OZil IP software provides in cataract extraction procedures.

Setting:

Complejo Hospitalario de Orense and Complejo Hospitalario de A Coruńa, Spain

Methods:

Patients were pre-screened for cataract grades 2 and above. Cataract surgery with torsional u/s was then performed on 48 patients evenly devised between two groups. All cases were performed with a phaco Chop technique through a 2.2 mm incision using ultrasleeve, a 45ŗ Minitip Kelman phaco tip and Intrepid Plus Micro-coaxial System. Group 1 was performed using torsional u/s with OZil IP energy management active @ a ratio of torsional/longitudinal of 0.5. Group 2 was performed with torsional u/s with OZil IP active @ a ratio of torsional/longitudinal of 1. Intraoperative measurements: cumulative dissipated energy (CDE), average torsional amplitude, effective phacoemulsification time, estimated fluid used and aspiration time

Results:

Study is still on going. Preliminary data indicates that efficiency of surgery is improved in group 1 and usage of overall energy is reduced .In both groups, it was noted that the torsional u/s provided very efficient cutting and reliable anterior chamber stability.

Conclusions:

All groups provided good surgical and postoperative clinical results. However the combination of Torsional ultrasound including the advanced software OZil IP at a 0.5 ratio resulted in more efficient surgery due to lack of chattering and better fluidic control. FINANCIAL DISCLOSURE?: No
