Background: Femtosecond laser-assisted LASIK (FS-LASIK) can make ultra-thin corneal flap accurately. MEL 90\nexcimer laser provides Triple-A ablation mode, which significantly reduces the amount of corneal tissue cutting.\nThis study aimed to investigate the visual and refractive outcomes in patients with high myopia after thin-flap FSLASIK\nusing the 500 Hz pulse rate of the Triple-A profile.\nMethods: This prospective study included 90 eyes from 90 patients received thin-flap FS-LASIK using the 500 Hz pulse\nrate of the Triple-A profile. According to the pre-operative spherical equivalence (SE), the treated eyes were divided\ninto two groups: the first group (ranged from - 9.0D to - 6.0D) and the second group (ranged from - 11.15D to - 9.0\nD). The parameters evaluated pre-operatively and 6 month post-operatively included uncorrected distance visual acuity\n(UDVA), corrected distance visual acuity (CDVA), SE, efficacy and safety index, posterior central elevation, and corneal\nhigher-order aberrations (HOAs)..............
