Abstract

To the Editor.  —In the April 1989 issue of the Archives, Arrowsmith and Marks1 concluded in their article on radial keratotomy that "Overall, these results indicate RK [radial keratotomy] to be safe and effective through 5 years after surgery for the vast majority of patients in this series." They indicate that after 5 years 26.8% of eyes operated on have hyperopia greater than 1 diopter and 6.5% have myopia greater than 2 D. This seems to me to be a failure rate of 33.3%, with 26.8% of patients (those with hyperopia) being distinctly worse off after surgery. I do not consider 66.6% to be a "vast" majority.Effectiveness is in the eyes of the beholder and apparently in only two thirds of the eyes of these patients.
