"Diffuse lamellar keratitis consists of a multi-etiologic syndrome that expresses variable degrees of inflammation at the interface of eyes operated by LASIK.37,38 As DLK after LASIK using a femtosecond microkeratome has not been reported previously, the 17% prevalence rate of this syndrome (even considering that just 6.25%—1 case—was greater than grade I or II) in our series has to be taken into account."

"The incidence of DLK after LASIK performed with a mechanical microkeratome is well documented (0.67% to 4%),2 although the incidence of DLK after LASIK performed with the IntraLase femtosecond laser (Abbott Medical Optics) is higher (17% to 19%),3 probably due to a more intensive inflammatory response after the procedure.4"
