Risk factors for ectasia after LASIK

摘要

In their letter1 about my 2007 article,2 Mohammad-pour and Jabbavand asked whether the assumed risk factors for developing ectasia, in and of themselves, increased the risk in a population of eyes that had been screened for topographic abnormalities. Before the 1998 article by Seiler et al.,3 keratoconus was considered a contraindication to laser vision correction. As corneal and refractive surgeons, we were aware of the topographic appearance of keratoconus eyes well before that date.4 I screened potential laser refractive patients for the then accepted signs of keratoconus and, subsequently, forme fruste keratoconus.
