We thank Knutsson and associates for their interest in our work. In their letter they remark that “the authors [we] imply that in the techniques described by Ghanem and associates and Knutsson and associates, the pachymetric measurements for the precalibrated diamond knife incision are performed using the ‘use of central or paracentral pachymetric values.’”

It is somewhat hard to understand the meaning of this remark, as “using the use” remains rather obscure. However, we can only agree with them when they state that reaching a depth as close as possible to the endothelium is the best guarantee for the success of pneumatic dissection. We also agree with them about a possible study to evaluate whether a deep trephination can prove superior, especially in terms of technical ease, to other approaches, including paracentral measurements and the use of precalibrated blades.
