Comparison of phacoemulsification parameters using active fluidic pressure control system versus gravity-fluidic syste

Objectives: This study aimed to compare the mean surgical time, cumulative dissipated energy (CDE), aspiration timeand estimated aspiration fluid parameters in phacoemulsification surgery using an active-fluidic pressure control sys tem (AFPCS) in comparison with gravity-fluidic system (GFS). Methods: The study analysed 202 eyes of 202 patients diagnosed with senile nuclear cataract and admitted to ourclinic. Phacoemulsification surgery was performed by an experienced surgeon using the Centurion Vision System de vice and the Infiniti Vision System device. After each case, the mean surgical time, CDE, aspiration time and estimatedaspiration fluid parameters were recorded. Complicated cases were excluded from the study. Results: In the AFPCS group, the mean age of the patients was 64.15±3.83 years, with the following results: mean surgi cal time, 11.88±5.44 min; CDE, 11.63±9.37; aspiration time, 3.91±1.49 min; estimated aspiration fluid, 71.89±27.56 ml. Inthe GFS group, the mean age of the patients was 64.99±3.80 years, and the following results were obtained: mean sur gical time, 14.35±3.93 min; CDE, 13.60±7.61; aspiration time, 5.56±1.8 min; estimated aspiration fluid, 101.23±15.62 ml. Conclusion: AFPCS was found to be more successful than GFS, with low-energy consumption, shorter surgical timeand better postoperative outcomes.
