Aim:

To compare the cumulative dissipated energy (CDE), aspiration fluid and aspiration time (AT) used during phacoemulsification using two surgical platforms.

Methods:

Consecutive eyes from patients undergoing cataract surgery were included. Lens opacities were graded from NO1NC1 to NO6NC6 using the LOCS III classification. Two platforms were evaluated: 1. Centurion® system with active-fluidics. 2. Infiniti® vision system with gravity-fluidics. CDE, AT and mean estimated aspiration fluid (EAF) were registered and compared.

Results:

A total of 216 eyes were evaluated. Mean age ± standard deviation was 78.3 ± 9.8 years (range 57-92). Significant differences were evidenced for overall CDE per nuclear density for cataracts Grade II to IV (p = 0.031, p = 0.045 and p = 0.032 respectively). AT showed a significant disparity for cataracts Graded II and III (p = 0.024 and p = 0.001), as the EAF (p = 0.001 and p = 0.042 respectively). All differences favoured the active-fluidics configuration group.

Conclusions:

Active-Fluidics System demonstrated to be more effective than Gravity-fluidics system for cataracts Grade II-IV phacoemulsification.
