This study introduces a robotic system to control forces during eye surgery, reducing retinal damage. Auditory feedback significantly lowered peeling forces, aiding surgeons in delicate membrane peeling procedures.

Area of Science:

  • Ophthalmology
  • Robotics
  • Biomedical Engineering

Background:

  • Vitreoretinal surgery involves delicate tissue manipulation with instruments as small as 0.5 mm.
  • High precision is required to avoid damaging the retina with imperceptible forces during procedures like membrane peeling.

Purpose of the Study:

  • To develop and evaluate a robotic system for regulating user-applied forces during vitreoretinal surgery.
  • To minimize the risk of retinal hemorrhage or tear by controlling forces during membrane peeling.

Main Methods:

  • A cooperatively controlled microsurgery robot platform was developed.
  • A custom micro-force sensing surgical pick was integrated for real-time force feedback.
  • A novel phantom was created to test robot control, force feedback, and auditory sensory substitution.

Main Results:

  • Auditory sensory substitution demonstrably decreased peeling forces in all tested scenarios.
  • Robotic force scaling combined with audio feedback showed the most significant reduction in peeling forces.
  • This combined approach also reduced overall task completion time.

Conclusions:

  • Robotic force regulation with auditory sensory substitution is a promising aid for vitreoretinal surgeons.
  • The developed system enhances safety and efficiency in delicate membrane peeling procedures.
  • Further integration of haptic and auditory feedback can improve surgical outcomes in microsurgery.
