The remaining A grade donor cornea on the Teflon block, now, devoid of the DM was trephined with a baron’s vacuum punch to a final size 0.25 mm larger than the recipient’s button. After punching, the graft was held at the posterior edge and trimmed in a fashion such that the posterior edge is thin and approximates to the thin host cornea. This provides a better approximation and adherence at the graft host junction.
