Effects Of Active Sentry® During Cataract Surgery Using Active Fluidics System

To investigate the clinical outcomes after cataract surgery using ACTIVE SENTRY^®.

Department of Ophthalmology, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea

This retrospective comparative case series study enrolled 458 eyes of 284 patients who underwent cataract surgery from August 2020 to June 2021 at Severance hospital. All cataract surgery was performed using Centurion Active Fluidics system by one surgeon. Two hundred eyes were performed with ACTIVE SENTRY handpiece, and 258 eyes were used conventional handpiece. Surgery associated parameters including total surgical time, cumulative dissipated energy (CDE), ultrasound usage time, aspiration time and total estimated fluid aspirated were compared between two groups. Postoperative visual acuity and complication rate were examined.

There were no significant difference in total surgical time, CDE, ultrasound usage time, and total estimated fluid aspirated between the ACTIVE SENTRY group and conventional group. The postoperative corneal endothelial cell count, complication rate and distance corrected visual acuity were also comparable in the two groups. The number of active surge mitigation (ASM) actuation increased in proportion to the severity of cataract.  

There were no significant differences between ACTIVE SENTRY group and conventional group in postoperative clinical outcomes. However, the number of ASM actuation increased in severe cataract patients, which suggested that ACTIVE SENTRY can be helpful in dense cataract surgery.
