Gender ratio	LM group	10/16	17/16	0.431
Gender ratio	HM group	24/27	17/23	0.678
IOP (mmHg)	LM group	17.63 ± 1.29	18.04 ± 3.07	0.146
IOP (mmHg)	HM group	18.03 ± 2.37	18.43 ± 2.14	0.509
REC (D)	LM group	−3.85 ± 0.87	−3.97 ± 0.74	0.708
REC (D)	HM group	−6.39 ± 0.79	−6.71 ± 1.14	0.230
OZD (mm)	LM group	6.80 ± 0.28	6.71 ± 0.09	0.114
OZD (mm)	HM group	6.57 ± 0.25	6.49 ± 0.25	0.095

FS-LASIK= femtosecond laser-assisted laser in situ keratomileusis, SMILE= small incision lenticule extraction; gender ratio = male/female, IOP= intraocular pressure measurement by DCT, REC= refractive error correction, OZD= optical zone diameter, LM= group low to moderate myopia group, HM= group high myopia group
