Ryu IH, Kim WK, Nam MS, et al. - In this retrospective observational study, researchers assessed corneal epithelial thickness change during medical treatment for eyes with myopic regression after femtosecond laser-assisted in situ keratomileusis (FS-LASIK). Participants in the study were 54 patients (84 eyes) diagnosed with myopic regression after FS-LASIK and treated using topical steroid and anti-glaucoma drugs. Using Fourier-domain optical coherence tomography before and after treatment, the corneal epithelial thickness was measured. For post-LASIK eyes with myopic regression, corneal epithelial thickness decreases proportionally with the magnitude of improvement of myopic regression during treatment with steroid and anti-glaucoma medications.
