    Area of Science:

    • Ophthalmology
    • Surgical Instrumentation
    • Corneal Transplantation

    Background:

    • Accurate preparation of donor corneal buttons is critical for successful corneal transplantation.
    • Current methods for handling and cutting corneal tissue can be challenging, potentially impacting graft quality.

    Purpose of the Study:

    • To introduce novel surgical instruments designed to enhance the precision and ease of preparing donor corneal buttons.
    • To address limitations in existing tools for corneal tissue manipulation.

    Main Methods:

    • Development of 12-mm media forceps specifically for grasping corneal tissue.
    • Creation of a variable curved Teflon block featuring centering targets for precise cutting and alignment.

    Main Results:

    • The new instruments facilitate improved handling and cutting of donor corneal buttons.
    • The design aims to increase accuracy and reproducibility in corneal graft preparation.

    Conclusions:

    • The developed instruments offer a potential advancement in the surgical preparation of corneal grafts.
    • These tools may contribute to better outcomes in corneal transplantation procedures.
