Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Surgical Technology

Context:

  • Ophthalmic microsurgery demands high precision and stable visualization.
  • Magnification in microscopes reduces the field of view, posing challenges for surgeons.
  • Current control methods may interfere with surgeon's natural movements.

Purpose:

  • To develop and evaluate an oculomotor control system for ophthalmic microsurgical microscopes.
  • To integrate an eye movement sensor for intuitive microscope positioning.
  • To ensure seamless control without disrupting the surgeon's visual functions or reflexes.

Summary:

  • A novel system integrates an eye movement sensor into the microscope lens for oculomotor control.
  • Surgeon's gaze directly manipulates microscope position, maintaining visual function and reflexes.

  • Laboratory and clinical trials (anterior/posterior segment surgery) validated the system's precision and sensitivity.

    • Impact:

    • Enables precise microscope navigation through intuitive gaze control.
    • Compensates for the reduced field of vision inherent in high-magnification microscopy.
    • Offers a non-invasive, highly sensitive tool to enhance surgical performance in ophthalmology.
