PURPOSE
To compare the clinical outcomes during phacoemulsification when using active fluidics (Centurion®) and gravity-based fluidics (Infiniti®) in immediate sequential bilateral cataract surgery. METHODS: From January 2015 to September 2015, 68 eyes of 34 patients with bilateral cataract were assigned to receive immediate sequential bilateral cataract surgery by Centurion® in one eye and Infiniti® in the other eye. We measured and compared intraoperative factors, including cumulative dissipated energy (CDE), ultrasound time, mean amount of balanced salt solution (BSS) used, and pain using a scale. Best corrected visual acuity (BCVA), central corneal thickness (CCT), and endothelial cell density (ECD) were also evaluated preoperatively and 1 month postoperatively. RESULTS: Intraoperative measurements showed significantly less CDE (5.05 ± 2.18 vs. 7.05 ± 3.82), ultrasound time (24.65 ± 9.68 vs. 34.95 ± 17.95 seconds), and mean amount of BSS used (37.06 ± 10.25 vs. 44.88 ± 16.38 mL) in the Centurion® group than in the Infiniti® group (p = 0.011, p = 0.005, p = 0.021, respectively). The intraoperative pain scale was 0.26 ± 0.51 in the Centurion® group and 0.50 ± 0.71 in the Infiniti® group, and was not significantly different (p = 0.121). BCVA, increase of CCT and decrease of ECD were not significantly different between the two groups at 1 month postoperatively. CONCLUSIONS: The efficacy of phacoemulsification in the Centurion® group was superior to that in the Infiniti® group. The level of intraoperative pain and clinical outcomes 1 month after surgery were not significantly different between the two groups. |
