We analysed refractive results, their predictability and efficacy, and the safety results of the different methods as secondary outcomes. Setting Refractive Surgery Unit of the Institut Català de Retina (ICR) in Barcelona, Spain. Design Retrospective, analytical observational study. Methods Retrospective and observational study of 654 eyes of 327 patients who underwent refractive surgery to treat their myopia or myopic astigmatism using LASIK, FS-LASIK, PRK, PRK Xtra or ICL-type lens implantation surgery were included. Results The correlation between the SE in absolute value was statistically significant in all techniques utilized, reaching higher values in the FS-LASIK and LASIK techniques, 0.774 and0.706 respectively, and lesser values in PRK (0.480) and PRK Xtra (0.482). A significant adjustment via a univariate linear regression model could be implemented in all techniques, albeit the R2 coefficient of determination values were higher than those for the FS-LASIK (0.599) and LASIK (0.494) techniques. Conclusions There is a positive correlation between post-surgical SE value and post-operative LogMAR UDVA. These regression models can be adjusted to predict the final UDVA according to the final SE. The techniques that are most influenced by the final SE in terms of their visual results are FS-LASIK and LASIK. 000095781 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000095781 590__ $$a3.24$$b2020 000095781 591__ $$aMULTIDISCIPLINARY SCIENCES$$b26 / 73 = 0.356$$c2020$$dQ2$$eT2 000095781 592__ $$a0.99$$b2020 000095781 593__ $$aMultidisciplinary$$c2020$$dQ1 000095781 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000095781 700__ $$aGomez-Barrera, M. 000095781 700__ $$0(orcid)0000-0001-6258-2489$$aGarcia-Martin, E.$$uUniversidad de Zaragoza 000095781 700__ $$aDuch, F. 000095781 700__ $$0(orcid)0000-0002-1402-3129$$aPolo, V.$$uUniversidad de Zaragoza 000095781 700__ $$aAbad, J.M. 000095781 7102_ $$11013$$2646$$aUniversidad de Zaragoza$$bDpto.
