The new Automated Pulse System (APS) for phacoemulsification and aspiration reduces ultrasonic energy and operation time during cataract surgery. This innovative system enhances efficiency without complex foot-pedal adjustments.

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Biomedical Engineering

Context:

  • Phacoemulsification and aspiration (PEA) is a common cataract surgery technique.
  • Current PEA systems utilize continuous ultrasonic energy, which can be inefficient.
  • High-frequency pulse systems offer potential improvements in energy delivery.

Purpose:

  • To develop and evaluate an Automated Pulse System (APS) for PEA.
  • The APS aims to regulate ultrasonic energy level and pulse frequency via a foot-pedal and suction mechanism.
  • To compare the efficacy of the APS against conventional continuous ultrasonic systems.

Summary:

  • The APS and conventional continuous ultrasonic systems were compared using a cataract model in pig eyes.
  • No significant difference in ultrasonic use time was observed.

Related Experiment Videos

  • The APS demonstrated a significant reduction in gross ultrasonic energy and operation time (p < 0.05).

    • Impact:

    • The APS automatically optimizes ultrasonic frequency and pulse percentage during nuclear emulsification.
    • This system offers an effective method to decrease ultrasonic energy utilization in pulse mode.
    • APS simplifies surgical control by eliminating the need for complex foot-pedal manipulation.
