Figure A9 — Comparison of total HOAs pre- and post-operatively. This figure visualizes the changes in total HOAs for each surgical procedure, represented by bars (pre-operative: diagonal stripe patterns, post-operative: solid colors). Red is used for LASIK, blue for PRK, and black for SMILE. Error bars indicate standard error, and asterisks (*) denote statistically significant differences (p < 0.05). PRK = photorefractive keratectomy, LASIK = laser-assisted in situ keratomileusis, SMILE = small incision lenticule extraction, HOAs = higher-order aberrations.
