I thank Dr Van Rij for his appreciation of my article.1 Hehad previously mentioned to me the references he is citing now in his letter(written communication, May 2002). However, I did not think these sourceshad to be referenced in my article. In the technique used by Ebeling and Carrel,2 the donor button is shaped like a mushroom, itsanterior part being larger than its posterior one. The surgical wound obtainedwith this technique does not share one of the main advantages of the procedureI presented1 (ie, resisting the effect ofintraocular pressure) and allows transplantation of only a limited amountof endothelium. Therefore, although a surgical wound with a lamellar componentwas used by these authors, substantial structural and functional differencesfrom the design I proposed do not allow a comparison between the 2 techniques.
