Area of Science:

  • Surgical Education
  • Medical Simulation
  • Ophthalmology and Vision Sciences

Background:

  • Laparoscopic simulator training effectiveness can be enhanced by novel feedback methods.
  • The utility of eye-tracking combined with video-feedback in surgical simulation is not well-understood.

Purpose of the Study:

  • To evaluate if visualizing gaze patterns during video feedback improves laparoscopic simulator performance.
  • To assess the impact of eye-tracking feedback on surgical residents' training experience.

Main Methods:

  • A mixed-methods pilot study involving 10 surgical residents randomized into experimental (gaze-overlay video feedback) and control (standard video feedback) groups.
  • Standardized tasks were performed on the Simball Box simulator, with quantitative (time, error rates) and qualitative data collected.
  • Eye-tracking data (gaze patterns) were analyzed using Tobii Pro.

Main Results:

  • The experimental group demonstrated significantly more focused gaze patterns on heat map analysis.
  • Subjective feedback value ratings did not significantly differ between groups.
  • Qualitative interviews highlighted the importance of expert mentorship alongside technological feedback.

Conclusions:

  • Eye-tracking feedback may promote more efficient visual strategies in laparoscopic training.
  • Further research with larger cohorts is needed to statistically validate initial performance gains.
  • Integrating simulation technology into structured curricula with expert guidance is essential for meaningful training.
