Abbreviations: A application, FS femtosecond laser, HC highest concavity, LASEK laser-assisted subepithelial keratectomy, LASIK laser-assisted in situ keratomileusis, N/A not available, SD standard deviation, SMILE small incision lenticule extraction. Specifically, we chose the subgroup data created in the study of Seafat et al. as this subgroup had a balance of spherical equivalent at baseline between the two intervention groups. Only one study provided the preoperative data of CST measurement. Therefore, we presented only the postoperative outcomes in this table
