Osher is correct and describes a very common condition with RK eyes. I had assumed everyone knew this and to maintain the size constraints of the editorial, left it out. The reference to the statement contains a warning not to operate early on RK eyes with surprise refractions in the early postoperative period. It does not hurt to have it mentioned again for those who may not be aware of it. I believe this topic was first brought up by Koch1 in his initial paper on IOL power errors in RK eyes in the 1980s.
