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.
