    This ophthalmic surgery training device uses a human scleral shell for suture practice. It helps novice surgeons develop tissue handling skills and understand proper suture depth.

    Area of Science:

    • Ophthalmology
    • Surgical Training
    • Biomedical Engineering

    Background:

    • Novice ophthalmic surgeons require hands-on training for developing essential surgical skills.
    • Current training methods may lack realistic tactile feedback for suture placement.
    • Access to consistent and ethical training materials is crucial for surgical education.

    Purpose of the Study:

    • To introduce a novel practice surgery device for ophthalmic surgeons.
    • To evaluate the device's utility in simulating suture placement on human sclera.
    • To enhance the training of novice surgeons in ophthalmic procedures.

    Main Methods:

    • The device utilizes an inflatable bladder supporting a glycerin-preserved human scleral shell from an eye bank.
    • A base includes a light source and a syringe mount for practicing suture techniques.

  • Each scleral shell can accommodate up to 100 practice sutures.

    • Main Results:

    • The device provides a realistic feel for needle passage through tissue, aiding skill development.
    • It allows practice with loupe or microscope magnification techniques.
    • Accidental deep needle placement causes scleral deflation, reinforcing the importance of superficial suturing.

    Conclusions:

    • This practice device offers a valuable tool for ophthalmic surgical training.
    • It effectively simulates key aspects of ophthalmic suturing, including depth perception.
    • The device emphasizes critical surgical principles, such as superficial suture placement, in a safe environment.
