Bimanual microphacoemulsification using the WhiteStar system is safe, as wound burns only occurred under extreme, non-clinical occlusion conditions. This confirms the technology

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Medical Device Engineering

Background:

  • Phacoemulsification is a common cataract surgery technique.
  • Ensuring intraocular safety during phacoemulsification is paramount.
  • New technologies require rigorous verification of thermal effects.

Purpose of the Study:

  • To investigate the temperature induction of bimanual ultrasound-based phacoemulsification.
  • To assess thermal effects using a bare aspiration needle and new proprietary technology.
  • To determine safety parameters during phacoemulsification with specific device settings.

Main Methods:

  • In vitro laboratory study using human cadaver eyes.
  • Utilized Sovereign phacoemulsification unit with WhiteStar system and a 19-gauge bare phaco needle.

  • Tested various occlusion conditions (unoccluded, aspiration occluded, flow and aspiration occluded) at 100% power, monitoring temperature and wound changes.

    • Main Results:

    • At 100% continuous power, temperatures remained below 27.3°C without occlusion.
    • With total aspiration occlusion, temperatures did not exceed 32.5°C.
    • Complete occlusion of both flow and aspiration led to a wound burn (45°C) within 45 seconds.

    Conclusions:

    • Wound burns were not produced under clinically relevant conditions with the tested microphacoemulsification technology.
    • Thermal safety was confirmed even at maximum energy settings, provided flow and aspiration were not completely occluded.
    • The WhiteStar system demonstrates safety for bimanual microphacoemulsification procedures.
