    This study shows a new system for evaluating donor corneal endothelium using specular microscopy is feasible and simple. This method allows for routine assessment of donor tissue quality for transplantation.

    Area of Science:

    • Ophthalmology
    • Corneal Transplantation
    • Microscopy

    Background:

    • Donor corneal tissue quality is critical for successful transplantation.
    • Routine assessment of donor corneal endothelium is essential for eyebanks.
    • Current methods may have limitations in efficiency or detail.

    Purpose of the Study:

    • To evaluate a novel system for routine specular microscopic assessment of donor corneal endothelium.
    • To assess the feasibility and simplicity of a new storage and viewing chamber for donor corneas.
    • To compare storage in the new chamber versus standard vials.

    Main Methods:

    • A modified specular microscope was used for noncontact scanning of donor corneas.
    • The system included a specialized chamber for simultaneous storage and viewing.

  • Forty-five human corneas were examined, with 13 paired corneas used for storage comparison.

    • Main Results:

    • The system demonstrated feasibility for routine specular microscopy of donor corneal endothelium.
    • The new chamber allowed for effective storage and viewing of donor tissue.
    • The method proved to be simple to implement in an eyebank setting.

    Conclusions:

    • Routine specular microscopy of donor corneal tissue is feasible and simple with the evaluated system.
    • The new chamber design offers advantages for donor tissue assessment and storage.
    • This approach can enhance the quality control of donor corneas for transplantation.
