Furthermore, when you implant a multifocal lens the change they have to adapt to is partly negative; you're degrading their image perception in exchange for multifocality. So far, the data indicate that once the improvement has occurred, it doesn't fade or require ongoing training to maintain.

When you alter their world, you undermine their control. If you train as many patients as possible both beforehand and afterwards, my experience suggests that you'll have a much lower number of failures and much greater number of successful outcomes.".

I'm always astonished when someone insists that visual neuroadaptation doesn't occur; or that if it occurs you can't influence it; or that you can influence it but a given approach couldn't possibly work.
