Abstract Details

Purpose:

The aim of the study is to verify the effect of fluidics on endothelial cells with gravity or controlled infusion pressures.

Setting:

Fondazione Poliambulanza Istituto Ospedaliero Brescia Italy

Methods:

40 eyes underwent facoemulsification, 20 patiets were operated in facoemulsification with infusion control through the pressurized bag controlled pressure, 20 with gravity fluid in gravity at a height of 90 cm. The pre op visual acuity was 4/10 +/- 0.5. The IOP was 16mmhg +/- 0.89. The intervention took place with the Centurion facememeter from Alcon, in peristaltic mode. The parameters used were: US 20% max, 450 mmhg vacuum, 42 cc / min fluorine. A pre-operative, post-operative, 3-month endothelial evaluation

Results:

Endothelial count values were for all 40 patients of 1780 +/- 153. The 20 patients who underwent gravity pressure had an endothelial count of 1720 +/- 160 The 20 patients who underwent controlled pressure had an average endothelial count of 1800 +/- 152. Between the two groups there is a difference even if statistically significant in favor of the group of patient with controled pressure. Further analyzes are ongoing and will be presented at the end of the study

Conclusions:

A more effective and efficient control of the anterior chamber reduces the number of lost endothelial cells during first moth postoperative.
