    K-Sol, a novel cornea preservation solution, allows for refrigerated storage of donor corneas for up to two weeks. Clinical results show K-Sol offers outcomes comparable to shorter preservation periods using traditional methods.

    Area of Science:

    • Ophthalmology
    • Tissue Engineering
    • Biomaterials Science

    Background:

    • Corneal transplantation relies on donor tissue preservation.
    • Current methods, like McCarey-Kaufman medium, have limited storage durations (2-3 days).
    • Need for extended preservation solutions to improve tissue availability.

    Purpose of the Study:

    • To evaluate the efficacy of K-Sol, a serum-free cornea preservation solution.
    • To compare K-Sol's long-term storage (up to 2 weeks) with standard methods.
    • To assess clinical outcomes of K-Sol preserved corneas in penetrating keratoplasty.

    Main Methods:

    • K-Sol was used for refrigerated storage of donor corneas.
    • Storage procedures were identical to McCarey-Kaufman medium protocols.

  • Clinical outcomes of 17 penetrating keratoplasty patients were analyzed.

    • Main Results:

    • K-Sol successfully preserved corneas for at least two weeks.
    • Clinical results were virtually identical to corneas preserved for 2-3 days in McCarey-Kaufman medium.
    • Effective use in challenging cases, including reoperations and retained IOLs, by less experienced surgeons.

    Conclusions:

    • K-Sol provides a viable alternative for extended corneal tissue preservation.
    • Extended preservation with K-Sol does not compromise clinical outcomes in penetrating keratoplasty.
    • K-Sol enhances donor tissue availability for corneal transplantation.
