TLDR
Compared to the Infiniti with IP mode, cataract surgery with the Centurion without IP mode is likely to be performed with less phacoemulsification energy and higher efficiency.Abstract:
Purpose: To compare the efficiency and safety of two phacoemulsification systems, the Infiniti with intelligent phacoemulsification (IP) and the Centurion without IP, in terms of intraoperative metrics of phacoemulsification and the occurrences of adverse events and intraoperative tip obstruction.
Design: Comparative case series.
Methods: A consecutive series of 340 eyes (151 eyes with the Infiniti, 189 eyes with the Centurion) was evaluated. A 2.4 mm sclerocorneal incision was used with the Infiniti, and a 2.0 mm incision was used with the Centurion. Phacoemulsification of the nucleus was performed using the phaco chop technique, with the IP function of the Infiniti turned on and the IP mode of the Centurion turned off. From among the parameters displayed on the panels of both devices, ultrasound (US) time, cumulative dissipated energy (CDE), aspiration time, and estimated balanced salt solution (BSS) aspiration volume were investigated and compared between the devices. Results: A comparison of all subjects found significant differences between the two devices in mean CDE (p=0.02) and mean aspiration time (p=0.003), but not in mean US time (p=0.43) or mean estimated BSS aspiration volume (p=0.07). For grade 3 nuclei, all parameters of mean US time (p=0.0044), mean CDE (p ≤ 0.001), mean aspiration time (p<0.001), and mean estimated BSS aspiration volume (p=0.001) showed significant differences favoring the Centurion.
Conclusions: Compared to the Infiniti with IP mode, cataract surgery with the Centurion without IP mode is likely to be performed with less phacoemulsification energy and higher efficiency.read more

TL;DR: The torsional mode may provide more effective lens removal with a lower level of phacoemulsification time and energy.

TL;DR: Torsional phacoemulsification was more effective than longitudinal phacoEmulsification in the amount of applied fluid and the quantity of US energy expended and with the torsional method, it was possible to maintain a constant ratio of amount of fluid flow to quantity ofUS energy used, regardless of nucleus density.

TL;DR: The torsional mode was as safe as the longitudinal mode in phacoemulsification for age‐related cataract as well as conventional longitudinal mode, according to Conference on Harmonisation‐E9 Guidelines.

Intraoperative performance and postoperative outcome comparison of longitudinal, torsional, and transversal phacoemulsification machines.
TL;DR: The torsional machine outperformed the transversal and longitudinal machines, with a lower mean needle time, less chatter, and improved followability, which corresponded to less corneal edema 1 day postoperatively and better visual acuity.

Comparison of cumulative dissipated energy between the Infiniti and Centurion phacoemulsification systems.
TL;DR: The Centurion phacoemulsification system required less energy to remove a cataractous lens with an adjusted average energy reduction of 38% across all surgeons in comparison to the Infiniti phaco Emulsification System.
