    Area of Science:

    • Ophthalmology
    • Surgical Instrumentation
    • Biomedical Engineering

    Background:

    • The DO-1 spatula needle is a standard tool in ophthalmic surgery.
    • Improvements in surgical needle design can enhance procedural efficiency and patient outcomes.

    Purpose of the Study:

    • To introduce and evaluate a novel spatula needle, designated DO-5.
    • To enhance the performance characteristics of the established DO-1 needle.

    Main Methods:

    • Modification of the DO-1 needle's diamond-shaped tip by lengthening.
    • Adjustment of the needle's widened shoulder by narrowing.

    Main Results:

    • The lengthened tip increases penetration force through the sclera.
    • The narrowed shoulder facilitates easier passage through the sclera.
