A biomechanical evaluation of rabbit corneas in M-K and Dexsol.
We compared the average force required to separate normal corneas at a 50% stromal depth, with the force required to separate corneas stored for 2, 5, 7, 10, and 14 days in either McCarey-Kaufman or Dexsol corneal storage medium. The required interlamellar separation force was calculated by standardizing the width of the test strips. The average required force for 35 fresh rabbit corneas (no storage) was 9.1 +/- 1.5 g/mm. There was no significant change in the required separation force after storage in either medium for up to 14 days.
