—Some comments are called for regarding the article entitled "Histopathology of a Case of Radial Keratotomy" by Stainer et al that appeared in the September 1982 Archives (100:1473-1477). The authors state that their analysis of a corneal button removed from a patient by radial keratotomy (RK) suggested that RK may carry a risk of optical and visual aberrations by producing "multiple defects."It should be emphasized that this was an eye with a pathologic condition to begin with, suffering from "considerable apical scarring" and keratoglobus requiring a corneal graft prior to the performance of what the authors call "radial keratoplasty." The patient had undergone an 8-mm corneal transplant that suffered from decompensation and persistent central graft edema. In addition, this eye suffered from what the authors call "high astigmatism." Despite these obvious pathologic characteristics, the unidentified surgeon apparently thought that RK could rescue this poor surgical result,
