To report a case with bilateral disciform keratopathy after laser in situ keratomileusis (LASIK).A 28-year-old man was referred to us with complaints of progressive painless diminution of vision, 5 days after having undergone bilateral simultaneous LASIK for hyperopia. The surgery was performed on the Chiron Technolas 217 excimer laser machine along with the hansatome, in which previously used blades were installed. Slit-lamp biomicroscopy revealed bilateral translucent disc-shaped lesions in the central cornea of both eyes. The lesions resolved after intense topical steroid therapy over a period of 3 weeks.Reuse of the microkeratome blade may have been the cause of this complication. The use of a new blade and meticulous cleaning of the microkeratome prior to use in each eye may help to prevent this complication.
