Fig. 2

Scatter plots showing the correlation between corrected SE and reductions in corneal nerve parameters. Correlation between the corrected SE and the reduction in CNFD (a), CNFL (b), and CFracDim (c) in the CLEAR eyes. Correlation between the corrected SE and the reduction in CNFD (d), CNBD (e), and CNFA (f) in the SMILE eyes. SE, spherical equivalent; CNFD, corneal nerve fiber density; CNFL, corneal nerve fiber length; CFracDim, corneal nerve fiber fractal dimension; CLEAR, corneal lenticule extraction for advanced refractive correction; CNBD, corneal nerve branch density; CNFA, corneal nerve fiber area; SMILE, small incision lenticule extraction
