Abstract Details


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


Fondazione Poliambulanza Istituto Ospedaliero Brescia Italy


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


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


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