A custom-made vitreoretinal surgical simulator using a silicone mold.

Area of Science:

• Ophthalmology
• Surgical Simulation
• Medical Device Development

Background:

• Vitreoretinal surgery requires extensive training.
• Traditional training methods often involve animal organs and specialized equipment, which can be costly and logistically challenging.
• There is a need for accessible and effective surgical simulators.

Purpose of the Study:

• To construct a custom-made vitreoretinal surgical simulator using a silicone mold.
• To evaluate the practicality and effectiveness of this novel simulator for training purposes.

Main Methods:

• A silicone mold was used to create a simulated eyeball.
• Expired surgical instruments and spray material were incorporated into the simulator design.
• Vitreoretinal experts evaluated the simulator's realism and utility through simulated procedures and questionnaires.

Main Results:

• The simulated eyeball closely matched actual eyeballs in size and rigidity.
• The silicone material provided good visibility and an effective peeling sensation for simulated membranes.
• Experts rated the simulator highly for its usefulness in preventing surgical complications and its overall training value.

Conclusions:

• The custom-made simulator is simple, cost-effective, and provides a valuable training environment.
• It reduces the need for travel to specialized facilities and the use of animal organs.
• Further validation across multiple training institutions is recommended.
