Abstract:
84 eyes that underwent femtosecond laser-assisted laser in situ keratomileusis ( FS-LASIK) , and 110 eyes that underwent small incision lenticule extraction ( SMILE) surgery were included in this prospective case se-ries study. HOAs included ( total HOAs, spherical aberration, horizontal coma aberration, and vertical coma aber-ration) were measured preoperatively after 1 week, 1 month , and 3 months postoperatively by Pentacam. The ab-errations were described as Zernike polynomials. Significantly increased total HOAs and SA and significantly de-creased vertical coma were noted at 1 week, 1 month, and 3 months after FS-LASIK ( P<0.05 ) . However, no significant increase was found in postoperatively horizontal coma. There were significant increases in total HOAs, SA, and horizontal coma and a decrease in the vertical coma at each postoperative examination in SIMLE group ( P<0.05 ) . The total HOAs and SA were significantly smaller in SMILE group than that in FS-LASIK group at 1 week, 1 month, and 3 months postoperatively. The changes in total HOAs and SA were also significantly smaller in SMILE group than that in FS-LASIK group at each postoperative examination. Compared with FS-LASIK, SMILE can induce fewer total higher-order aberrations and spherical aberration after operation.
