·AIM:To evaluate the clinical classification treatment of diffuse lamellar keratitis(DLK)after LASIK.·METHODS:Nineteen patients 21 eyes of DLK after LASIK from April 2008 to September 2009 in our hospital were collected.They were given clinical classification treatment according to corneal layer inflammatory extent.The clinical symptoms,corneal infiltration and scope of vision,refractive and intraocular pressure were observed before and after treatment 1 day,3,5,7,10 days and 1 month.·RESULTS:Most of patients presented mild symptom,including degrees Ⅰ:18 eyes,degree Ⅱ:2 eyes,degree Ⅲ:1 eye.Through the appropriate classification of glucocorticoid treatment,corneal flap lesions of inflammatory cell infiltration mostly subsided within 1 week.1 month after treatment,uncorrected visual acuity was significantly increased,reaching preoperative best-corrected visual acuity.Corneal signs,visual acuity and refractive error recovery levels among the various DLK gradings and also among the different treatments in the cases.Were not significantly differenct.There was no glucocorticoid-induced high intraocular pressure.·CONCLUSION:Clinical classification has a guiding role in glucocorticoid classification treatment of DLK.·
