Yes, multifocal implants have 'ghosting' issues, due to the fact that the Distance & Near focussing areas are (usually) in alternate circles radiating out from the centre. The brain is constantly receiving 2 images and has to sort them out. Usually not bad in brightly lit conditions, but more difficuly when dim. Some people have no issues, some don't sem to cope well with it.
An alternative (and more modern) design has the implant lens actually flex within the eye, something similar to normal 'accommodation', but it appears the effect seems to diminish with time.
