Through-Focus Optical Bench Performance of Extended Depth-of-Focus and Bifocal Intraocular Lenses Compared to a Monofocal Lens

“…Typical sources of glare include cata-ract or IOL edge. 8,9 In contrast, halo is defined as more regular patterns around an object mainly caused by optical designs of IOLs such as diffractive and refractive rings included in multifocal IOLs. As shown in PSF images at 0.00 D of defocus in Figure 4, the glare pattern was dominant in the PSF images of monofocal and EDOF IOLs.…”
