Abstract: PURPOSE To compare the outcomes of femtosecond laser assisted in situ keratomileusis (FS-LASIK) with transepithelial photorefractive keratectomy (T-PRK) for the correction of high-grade astigmatism. METHODS Medical records of patients with astigmatism of 2 diopters (D) or… read more here.
