Objective: Fi evaluate effects a previous myopic laser in-situ keratomileusis (LASIK) pan decrease inna contrast sensitivity afta implantation a diffractive multifocal intraocular lens (MF-IOL). Methods: Retrospective case series did include eyes weh did implant diffractive MF-IOLs afta myopic LASIK. Contrast sensitivity did measure 1 month postoperatively an di area unda log contrast sensitivity (AULCSF) did calculate. Principle component analysis (PCA) was used fi extract principal factors related wid di previous LASIK an MF-IOL implantation. Effects a decrease inna postoperative AULCSF an contrast sensitivity at each spatial frequency did evaluate using step-wise multiple regression analysis. Results: Twenty-six eyes a 20 patients did include. Di mean postoperative uncorrected distance visual acuity was -0.06 ± 0.13 logMAR (20/17 in Snellen) an all eyes achieved 20/20 or betta. Di PCA determine central corneal thickness (CCT), distance-corrected near visual acuity, an absolute manifest refraction as principal factors. Di multiple regression analysis did show seh di AULCSF did show significant decrease wid a thinner CCT (P=0.017), while a particular trend neva did find inna di analysis results at di spatial frequencies. Conclusion: Degradation in contrast sensitivity afta implantation a MF-IOLs inna post-LASIK eyes was more affected by di amount a di previous LASIK corrections.
