    Area of Science:

    • Ophthalmology
    • Biomedical Engineering

    Background:

    • Dry eye disease affects numerous individuals, impacting ocular surface health.
    • Current treatments, primarily eye drops, offer limited efficacy for severe cases or require frequent administration.
    • A need exists for sustained solution delivery methods for managing chronic dry eye.

    Purpose of the Study:

    • To introduce and evaluate a novel apparatus for prolonged ocular surface solution delivery.
    • To assess the efficacy of this apparatus in alleviating symptoms of severe dry eye disease.

    Main Methods:

    • Development of a mechanical apparatus comprising a replaceable plastic tank under pressure.
    • Integration of capillary tubing for continuous solution application to the eye's inner canthus.
    • Clinical assessment of the apparatus in patients with severe dry eye refractory to conventional treatments.

    Main Results:

    • The described apparatus successfully delivered solutions over extended periods.
    • Significant alleviation of dry eye symptoms was observed in patients with severe conditions.
    • The device proved effective where other treatments had failed.

    Conclusions:

    • The novel apparatus offers a promising solution for long-term management of severe dry eye.
    • Continuous ocular surface hydration and drug delivery can be achieved with this device.
    • This technology represents an advancement in treating refractory dry eye disease.
