I enjoyed the article by Afshari et al¹ on the optimal size and location for corneal rotational autografts using a simplified mathematical model and would like to note that the article confirms previous studies on mathematical models for the calculation of the size and location of corneal autografts.^2-5 In these previous investigations, the equation for the optimal trephine diameter was diameter_(trephine) = [ x diameter_(cornea)] – [ x e], with e being the preoperative distance between the corneal center and the nearest edge of the opacity covering the corneal center.⁴ The postoperative diameter of the optical zone was [2 x diameter_(trephine)] – diameter_(cornea). A postoperative clear optical zone of half of the corneal diameter was achieved if the opacity just touched but did not extend beyond the corneal center. For a postoperative optical zone of at least 30% and 40% of the corneal diameter, . . . [Full Text of this Article]
