Purpose:
The aim is to evaluate the efficiency of a new ultrasonic chopper in camparison with standard phaco tip in cataracts of different densities.
Setting:
: Klinika ocni a esteticke chirurgie, Zlin, Czech Republic
Methods:
Cataract surgery was performed on 3 groups of patients who were divided based on the grade of cataract: 1, 2 and 3. Each group had 30 members who underwent standard cataract removal performed purely with Miniflared Kelman 45° tip and 30 members with Ultrachopper used for a chop step and Miniflared Kelman 45° tip for the rest of the cataract removal. All cases were performed on Infinity Vision System (Alcon) and Intrepid Micro-coaxial System. All cases were performed by a single surgeon and single surgical equipment, 2,2mm incision, temporal approach. Total time of the procedure, cumulative dissipated energy and fluidics used were measured and compared in each group. Possible complications were monitored.
Results:
In all grades of cataract Ultrachopper use resulted in more efficient surgery. There was a slight reduction of cumulative dissipated energy (5% in grade 3 patients, 4% in grade 2 and % in group 1) as well as fluidics used (approx.. 6% for each group). Especially in group 3 chop step was much more convenient and smooth. Total time of procedure remained statistically unchanged and no peroperative complications were reported.
Conclusions:
All patients had good postoperational results. Even though recommended mainly for dens catraracts, Ultrachopper seems to be a good option how to perform an efficient and safe cataract procedure in patients with all grades of cataracts. It improves convenience and does not limit the possibility to use Ozil Torsional Handpiece.
