Figure A10 — Comparison of spherical aberration (Z4, 0) pre- and post-operatively. This figure illustrates the changes in spherical aberration, with pre-operative measures in diagonal stripe patterns and post-operative in solid colors. Red indicates LASIK, blue PRK, and black SMILE. Error bars represent standard error, and asterisks (*) signify statistically significant differences (p < 0.05). PRK = photorefractive keratectomy, LASIK = laser-assisted in situ keratomileusis, SMILE = small incision lenticule extraction, HOAs = higher-order aberrations.
