Abstract Details


The aim of the study was to investigate whether the Centurion® Vision System’s Active Fluidics™ technology might contribute to less corneal endothelial cell loss compared to the gravity fluidics technology after uneventful phacoemulsification.


This prospective study was conducted in June and July 2015 at the operative unit of ophthalmology, hospital of Chiari


Thirty eyes of 30 patients were randomly assigned to two groups: 15 patients (group A) underwent cataract surgery using the Centurion® Vision System’s Active Fluidics™ technology and 15 patients (group B) using the gravity fluidics technology. Corneal endothelial cell counts were done in the central part of the cornea using a non-contact automatic microscope preoperatively, 7 and 30 days after surgery. A single examiner performed all the measurements. All operations were done by the same surgeon. Statistical analysis was performed by using Student’s t test. A p value less than 0.05 was considered statistically significant.


Preoperative mean cell density (MCD) was 2437 cells/mm² in group A and 2085 in group B (p=0,07). In group A MCD was 2175 after 7 days (p=0,09), and 2004 after 30 days (p=0,04). In group B MCD was 1554 after 7 days (p=0,02) and 1510 after 30 days (p=0,01). The percentage of cell loss in group A was 11% after 7 days, and 18% after 30 days; in group B it was 26% after 7 days and 28% after 30 days.


The results of the study suggest that the Centurion® Vision System’s Active Fluidics™ technology might lead to a corneal endothelial cells’ saving compared to the gravity technology at least for the first 7 days after surgery. This preliminary finding is interesting, although the number of patients is small: therefore, larger studies are necessary to confirm this result.
