    An adjustable length infusion needle was developed for Ocutome vitrectomy. This innovation eliminates the need for tip visualization, significantly reducing the risk of uveal infusion during the procedure.

    Area of Science:

    • Ophthalmology
    • Surgical Instrumentation

    Background:

    • Ocutome vitrectomy requires precise control of infusion during surgical procedures.
    • Accidental infusion into the uvea poses a significant risk to patient outcomes.

    Purpose of the Study:

    • To develop and evaluate an adjustable length infusion needle for Ocutome vitrectomy.
    • To mitigate the risk of uveal infusion during vitrectomy surgery.

    Main Methods:

    • Design and fabrication of an adjustable length infusion needle compatible with Ocutome vitrectomy systems.
    • In vitro and/or in vivo testing to assess needle functionality and safety profile.

    Main Results:

    • The adjustable needle allows for precise control over infusion depth.
