Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Cataract Surgery

Background:

  • Phacoemulsification is a standard cataract surgery technique.
  • Optimizing ultrasonic energy delivery is crucial for patient outcomes.
  • Different machine configurations may impact energy efficiency.

Purpose of the Study:

  • To compare phacoemulsification times and power usage across three Alcon Legacy 20000 machine configurations.
  • To evaluate the impact of the Advantec upgrade and NeoSoniX technology on energy efficiency.

Main Methods:

  • A randomized prospective study of 410 cataract cases.
  • Comparison of Standard Legacy 20000, Advantec upgraded Legacy 20000, and Advantec Legacy 20000 with NeoSoniX.
  • Analysis of phacoemulsification time and average percentage of maximum power expenditure.

Main Results:

  • No significant difference in phacoemulsification time was observed among the three configurations.
  • The Advantec Legacy 20000 with NeoSoniX demonstrated a significant reduction in power consumption (27.56%) compared to Standard (38.00%) and Advantec (37.97%).
  • NeoSoniX incorporation led to a 27.5% reduction in ultrasonic energy expenditure across all nuclear densities.

Conclusions:

  • The addition of NeoSoniX rotational energy to the phacoemulsification machine significantly reduces ultrasonic power expenditure.
  • This technology offers improved energy efficiency in cataract surgery.
  • NeoSoniX is a valuable upgrade for optimizing phacoemulsification procedures.
