    TC Earle Solution is the most effective commercial option for maintaining corneal thickness and endothelial viability. Glucose and bicarbonate are essential for its efficacy, with minimal difference compared to the experimental GBR Solution.

    Area of Science:

    • Ophthalmology
    • Corneal Preservation
    • Biomedical Engineering

    Background:

    • Maintaining corneal health post-explantation is critical for transplantation success.
    • Various electrolyte solutions are used, but their comparative efficacy varies.
    • Endothelial cell viability is a key indicator of corneal health.

    Purpose of the Study:

    • To evaluate the effectiveness of different electrolyte solutions in preserving corneal thickness and endothelial viability.
    • To identify the optimal commercially available solution for corneal storage.
    • To determine the essential components contributing to solution efficacy.

    Main Methods:

    • Comparison of five electrolyte solutions: Plasma-lyte, TC Medium 199, TC Medium 199 with additional bicarbonate, TC Earle Solution, and glutathione bicarbonate Ringer Solution.

  • Assessment of corneal thickness and endothelial cell viability after storage.
  • Analysis of the role of glucose and bicarbonate in solution efficacy.

    • Main Results:

    • TC Earle Solution demonstrated the highest effectiveness among commercially available options.
    • Minimal difference in efficacy was observed between TC Earle Solution and the experimental glutathione bicarbonate Ringer Solution.
    • Glucose and bicarbonate were identified as crucial components for TC Earle Solution's effectiveness.

    Conclusions:

    • TC Earle Solution is a highly effective commercially available option for corneal preservation.
    • The inclusion of glucose and bicarbonate is vital for the efficacy of TC Earle Solution.
    • Further research may explore the glutathione bicarbonate Ringer Solution as a viable alternative.
