This study developed a goniotomy surgical training course using various eye models. Trainees reported increased confidence in performing goniotomy after completing the course, recommending it for fellowship programs.

Area of Science:

  • Ophthalmology
  • Surgical Education

Background:

  • Goniotomy is a crucial surgical procedure for treating certain types of glaucoma.
  • Effective training models are essential for preparing ophthalmology fellows for goniotomy.
  • Current training methods may lack sufficient hands-on experience with realistic surgical simulation.

Purpose of the Study:

  • To design and evaluate a novel model-system instruction course for goniotomy training.
  • To assess the effectiveness of different simulation models in preparing trainees for live goniotomy procedures.

Main Methods:

  • An experimental study involving three pediatric ophthalmology fellows and one recent graduate.
  • Piloted three model systems: human cadaver eyes (with/without Marty Head simulator) and artificial eyes in the Marty Head.

Related Experiment Videos

  • Training included didactic lectures, video review, and hands-on practice with operating microscopes.

    • Main Results:

    • Trainees rated didactic materials highly but felt they offered limited new information.
    • Artificial eyes in the Marty Head provided the best visibility and ease of setup.
    • Human cadaver eyes offered a better surgical feel and transferability, despite slightly lower visibility.
    • All participants reported increased confidence and readiness to perform goniotomy on patients.

    Conclusions:

    • The developed model-system instruction course effectively prepares trainees for goniotomy.
    • This training approach has the potential to reduce patient risks during goniotomy procedures.
    • The course is recommended for inclusion in pediatric ophthalmology fellowship curricula.
