The effects of corneal incisions of different types on the corneal endothelium in cadaver eyes was studied by scanning electron microscopy. In all cases the perforations were made with a diamond knife, but in case 1) the opening was enlarged in both directions with scissors, in case 2) a partly perforating groove was made on one side, and an enlargment only with sciccors on the other, and in case 3) a long full thickness incision with diamond knife only was made. The greatest damage to the endothelium was induced by the scissors, the damage was less when partial thinning was performed before the opening with scissors, and the least trauma was seen when a diamond knife only was used. The cell loss was maximally calculted to be about 8% of the endothelial cell population when incision with scissors was performed compared with 2–3% with diamond knife incision.
