Figure 2

Comparison of the planned and achieved central CST reduction with nomogram. The coefficients of determination (R2) and regression equations are displayed. Points plotted above the dotted lines indicate that the planned central CST reduction underestimates the achieved central CST reduction and points plotted below the dotted lines indicate that the planned central CST reduction overestimates the achieved central CST reduction. SMILE small-incision lenticule extraction. FS-LASIK femtosecond laser-assisted in situ keratomileusis. CST corneal stromal thickness.
