Comparison of Tear Cytokines and Clinical Outcomes Between Off-flap and On-flap Epi-LASIK With Mitomycin C

Abstract

Off-flap epi-LASIK with MMC offers faster corneal epithelial healing and visual recovery, and temporary less haze than on-flap epi-LASIK with MMC. The lower tear levels of bFGF, PDGF-BB, IL-8, and TNF-α in the offflap group 2 hours after surgery may suggest a possible mechanism for the clinical differences.
