    Area of Science:

    • Ophthalmology
    • Surgical Innovation
    • Medical Devices

    Background:

    • Microsurgery requires specialized tools to protect delicate eye structures.
    • High-intensity surgical lights pose a risk of retinal damage.
    • Existing protective measures may be costly or complex.

    Purpose of the Study:

    • To develop a low-cost, easily accessible retinal light filter for microsurgery.
    • To provide a practical solution for preventing phototoxicity during ophthalmic procedures.

    Main Methods:

    • A 6-mm circular filter was created from the edge of a Weck-cel package.
    • The filter was soaked in balanced salt solution prior to use.
    • The filter was applied to the cornea during microsurgical procedures, with removal during anterior chamber manipulations.

    Main Results:

    • The devised filter effectively blocks potentially harmful light from reaching the retina.
    • The filter is simple to construct and requires no specialized equipment.
    • The method is cost-effective, utilizing readily available materials.

    Conclusions:

    • This no-cost filter offers a safe and practical method for retinal protection during microsurgery.
    • The innovation provides an accessible solution for reducing the risk of light-induced retinal injury in ophthalmic surgery.
