Mean reading speed, based on reading acuity and mean critical print size of two different multifocal IOLs (MIOL). Forty eyes per group were investigated. Note the significant difference in the mean reading speed between the diffractive and the refractive MIOL at reading acuities ranging from logRAD 0.7 to 0.3 (n.s., not significant)
