Popis: AIM: To compare the clinical effect of femtosecond-assisted laser in situ keratomileusis(FS-LASIK)and trans-epithelial photorefractive keratectomy(TransPRK)using 750Hz ablation frequency and smart pulse technology(SPT)in the correction for moderate myopia.METHODS: A non-randomised, prospective cohort study was conducted on the included 48 patients(90 eyes)treated with FS-LASIK and 47 patients(90 eyes)treated with TransPRK. All eyes were moderate myopia(spherical equivalence -3.00~-6.00D). Both FS-LASIK and TransPRK were performed by Schwind Amaris 750S excimer laser. Visual acuity, refraction and corneal high order aberration were analyzed before and at 6mo after surgery, respectively, to evaluate the surgical efficacy.RESULTS: The diopters at 6mo after the surgery of FS-LASIK and TransPRK were emmetropic and relatively stable. There was no significant difference in preoperative and postoperative SE between the two groups(P>0.05). The total high order aberration, spherical aberration, and vertical coma at 6mo after surgery in the FS-LASIK group and TransPRK group were significantly higher than those before surgery(all P
