This study validates a low-cost cataract surgery simulation using basic materials. The technique effectively trains essential microsurgical skills, offering a practical adjunct to existing surgical education methods.

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Medical Simulation

Background:

  • Cataract surgery training requires effective simulation methods.
  • Existing simulation techniques can be costly and inaccessible.
  • There is a need for adaptable, low-cost training tools.

Purpose of the Study:

  • To evaluate the subjective validity of a cost-effective cataract surgery simulation.
  • To assess the adaptability and basic technology requirements of the simulation.
  • To determine the relevance of the simulation for developing microsurgical skills.

Main Methods:

  • Developed and filmed simulation techniques mimicking phacoemulsification cataract surgery using everyday materials.
  • Created a video combining simulated and live surgery steps.

  • Distributed an online subjective validation questionnaire to ophthalmologists.

    • Main Results:

    • 99% of participants found the simulation explanations clear and instrumentation user-friendly.
    • 79% agreed the simulated techniques felt realistic.
    • 90% confirmed the techniques reflected essential surgical skills, with 74% finding them relevant for transferable microsurgical dexterity.

    Conclusions:

    • The developed cataract surgery simulation technique demonstrates subjective validity.
    • This cost-effective model serves as a valuable adjunct to intraocular and virtual reality training.
    • The simulation removes cost barriers and enhances exposure to real surgical instruments.
