Objective: To evaluate effects of previous myopic laser in-situ keratomileusis (LASIK) on decrease in contrast sensitivity after implantation of diffractive multifocal intraocular lens (MF-IOL). Methods: Retrospective case series included eyes that were implanted diffractive MF-IOLs after myopic LASIK. Contrast sensitivity was measured 1 month postoperatively and the area under log contrast sensitivity (AULCSF) was calculated. Principle component analysis (PCA) was used for extracting principal factors related with the previous LASIK and MF-IOL implantation. Effects of decrease in postoperative AULCSF and contrast sensitivity at each spatial frequency were evaluated using step-wise multiple regression analysis. Results: Twenty-six eyes of 20 patients were included. The mean postoperative uncorrected distance visual acuity was -0.06 ± 0.13 logMAR (20/17 in Snellen) and all eyes .. View More»
