This study aimed to compare the efficacy and safety of Femto-LASIK, PRK, and Artiflex/Artisan phakic lens implantation in the surgical correction of myopia at different moments of postoperative follow-up; to propose a linear predictive model of visual acuity without correction at five years of refractive procedures; and to evaluate its validity. Methods. A retrospective observational analysis was performed. Patients were clinically reviewed after three months, one year, two years, and five years. Univariate and bivariate analyses and a multivariate linear regression model were performed. Results. Six hundred seventy-nine eyes were analyzed: 18.9% Artiflex, 2.8% Artisan, 42.3% Femto-LASIK, and 36.1% PRK. There were significant differences in effectiveness and safety after five years when comparing Artiflex/Artisan versus PRK and Femto-LASIK (penAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/ArtiflexArtisanFemto-LASIKPRKcorneal laserhigh myopiairis-clawphakic lens implantresearch article36292351open access10.3390/healthcare10101904PMC9601292https://www.mdpi.com/2227-9032/10/10/1904/pdf?version=1666585904https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9601292/pdf
