Overview
Diffuse lamellar keratitis (DLK) is sterile interface inflammation after LASIK or flap-based refractive surgery. It is time-sensitive because interface inflammation can threaten vision, but it must be differentiated from infectious keratitis. Optometry should recognise interface haze/infiltrates, document severity and red flags, and arrange urgent refractive surgeon/ophthalmology review. Steroid escalation, flap lift, and interface irrigation are specialist pathway actions.
