The procedure is for Presbyopia, so is really more for personal satisfaction rather than any true defect.

Sometimes, ones distance vision would also experience lack of sharpness, because only the dominant eye is fitted with distance vision lens. In multifocal IOL pseudophakes, neural plasticity probably explains several things: the commonly observed improvement in contrast sensitivity at six months postop; better contrast sensitivity in bilateral multifocal IOL pseudophakes compared to unilateral multifocal pseudophakes; and perceptual learning after surgery, when experience produces reasonably permanent changes in perception. Wouldn't it make sense to perform the procedure on the left? One available system designed to enhance adaptation following implantation of multifocal IOLs is an Internet-based program offered by RevitalVision (using technology pioneered by its predecessor, NeuroVision), based in Lawrence, Kan.
