Abstract Details


To compare the safety and efficacy of active versus passive phacoemulsification fluidics systems in hard cataract.


Wuhan Aier Eye Hospital, Aier School of Ophthalmology, Central South University


In this prospective randomized comparative study, 100 eyes were assigned to 2.2-mm microcoaxial phacoemulsification using the active fluidics systems (study group) or passive fluidics system (control group). Main outcome measures included cumulative dissipated energy (CDE), amount of balanced salt solution (BSS) used, and changes in central corneal thickness (CCT). and surgical complications.


The mean CDE was significantly less in the study group compared with the control group (P< 0.01). The mean time in foot pedal position 3 (FP3) for varying grades of cataract density ranged from 14.3 to 28.2 seconds in the study group and from 17.1 to 41.7 seconds in the control group, which was statistically significant (P < 0.01). The amount of BSS used was 52.19 mL in the study group and 67.05 mL in the control group. On the first postoperative day, CCT was significantly different between the study and the control group (P < 0.01).


The 3 parameters (CDE, FP3 and BSS amount) were found to be effective with no significant complications. The active phacoemulsification fluidics systems with less postoperative corneal edema, and thus patients had a more rapid visual recovery in hard cataract.
