Fig. 4From: Comparison of early changes in tear film protein profiles after small incision lenticule extraction (SMILE) and femtosecond LASIK (FS-LASIK) surgeryDifferences between preoperative and 1-month postoperative tear protein levels for SMILE (A) and FS-LASIK (B). Volcano plots visualize no statistically significant proteins based on log2 fold change (x-axis) and adjusted p-value (y-axis) when preoperative and 1-month postoperative tear levels are compared for SMILE (A) and FS-LASIK (B)Back to article page
