In Reply.  —We certainly agree that long-term studies to determine the susceptibility of the cornea to blunt trauma following radial keratotomy are important. Our study yielded information only about immediate postoperative weakness in the cornea and was not designed to assess corneal integrity following wound healing.We did refer to an unpublished study that documents a trend toward corneal weakness three months following radial keratotomy in a rabbit model (Frederick Kremer, MD, oral communication, May 1981). However, corneal wound healing may be different in the rabbit than in the primate.Dr Steel's studies of the effect of elevated pressures on the cornea six months following radial keratotomy were certainly of interest. However, pressures leading to rupture of a corneal wound or of the sclera would be far in excess of those he used. Dr Steel raises an important issue, and we are currently proceeding with studies to assess the integrity
