"Vision has been shown to improve in multifocal IOL patients who engage in perceptual learning with these kinds of visual tasks," Dr. Mainster notes.1,2 "This makes sense, because the contrast sensitivity of the overall visual system is equal to the transfer of optical contrast through the cornea and lens, (the modulation transfer function) multiplied by the contrast sensitivity of the retina and brain (the neural transfer function).3 That's why any improvement in neural adaptation in the retina and brain after multifocal IOL surgery produces a corresponding improvement in overall contrast sensitivity functioni.e., an improvement in functional vision.". "Adaptation can happen quickly, as when we adapt to light or dark, but some types of adaptation happen very slowly over weeks or months," notes Martin A. Mainster, MD, PhD, FRCOphth, professor of ophthalmology at the University of Kansas School of Medicine.

I suggest you talk this over with your ophthalmologist. Multifocal IOLs and MaculopathyHow Much is Too Much?

Another disadvantage is some people dont adapt to monovision. . Did you have regular contacts before?

We're stimulating neural interactions, and we monitor the patient's responses; if a particular type of stimuli doesn't generate improved vision, we alter the program until we see the patient's vision improving. Only one eye is being utilized to see near or far, but the goal of monovision is that somehow the brain blends the clarity of one eye's image with the blurred input from the other.
