Is It True That Patients Who Develop Keratoconus After LASIK Always Had Keratoconus?

+2

Patients who develop keratoconus after LASIK either 1) had keratoconus to begin with  2) had a tendency for developing keratoconus which was not evident on pre-operative examination or 3) had an excessively thick flap created or excessively deep ablation so that the remaining corneal bed was too thin for tectonic support.  The incidence of #3 is very low with modern LASIK equipment.  The goal of pre-operative screening is to identify those patients who have keratoconus (#1) and to eliminate them, and also to identify those in the second category by careful screening of the various corneal parameters.  Even with modern screening techniques, there will be some patients who have a normal exam, but they have tendency to develop keratoconus as it is a genetic disease.
