Abstract Details



Purpose:

To assess whether the control pedal double-linear impact on the loss of endothelial cells

Setting:

Chiari Hospital, Az. Osp. Mellino Mellini Chiari (BS) Italy

Methods:

100 patients with a variety of consistency of cataracts have been subjected to four surgeons of different experience, for intervention in the clear cornea phacoemulsification under topical anesthesia with Stellaris PC Machine B&L. The patients were divided into 4 groups: Group 1 technique Facochop with , double linear linear pedal control 5-10% max us, 600 mm Hg vacuum and 90 mm Hg bottle high Group 2 phaco chop technique with linear control pedal, 25 us max, 450 mm Hg vacuum, 110 mm Hg bottle high Group 3 Divide and Conqueor with dual pedal control, u.s. 20% with 80mmHg in the first stage and 450 in the second phase vacuum group 4 technique Divide and Conqueor with linear pedal control 20% u.s. max, with 80mmHg in the first stage and 450 in the second phase of vacuum. Each patient performed an endothelial count preop and 30 days after surgery.

Results:

The average use of u.s. Group 1 was 4.59% with an effective use of 0:00.89 sec in group 2 the u. s. average was of 7.63 with an effective use of 0:02.32 sec. In group 3 the u. S. average was 8.80% with an actual time of 0:15.45 sec, while group 4 the u. s. average was of 13.50% with an actual time of 0:23.12 sec. The mean pre-intervention in group 1 was 2556.48 cells, in group 2 of 2586.37cells, 2734.80 cells in group 3, and 2593 cells in group 4. The mean count in group 1 after 30 days was 2296.90 cells, in group 2 of 2114.85cells, 2303.6 of cells in group 3 and group 4 of 1974.16cells. The average loss in group 1 was 11%, in group 2 was19%, in group 3 was 16% ,in group 4 was 24%.

Conclusions:

The use of dual linear control, any technique you use, can save an average of U.S. and consequently a reduction in the percentage of loss of endothelial cells. The technique of the control of the pedal in double linear is then, thanks to the technology which is available Bausch & Lomb, the best choice for obtaining more satisfactory results for the patient.
