Gonzalez–Salinas R, et al. – The cumulative dissipated energy (CDE), aspiration time and estimated aspiration fluid used amid phacoemulsification cataract surgery utilizing two phacoemulsification systems are compared in this study. According to the outcomes obtained, the active–fluidics Centurion ® phacoemulsification system achieved higher surgical efficiency than the gravity–fluidics Infiniti ® IP system for NII and NIII cataracts.
