Granted, I got my medical degree at law school; but my (potentially flawed) thinking is this:

You are removing your anatomical lens and replacing it with an artificial intraocular lens.

If you wear corrective lenses, this may be an opportunity to obviate them by making the correction(s) with intraocular lenses.

I believe multifocal lenses are the functional equivalent of progressive lenses, which is essentially a three-zone lens, with the middle zone being the narrowest; it is my understanding that progressive lens ranges are shaped like an hour glass, with wider fields of view at the top and bottom, which are the distance and reading fields, respectively.  The middle range is basically the dashboard/computer/phone field, which is increasingly important for many people.

If you put a multifocal lens inside your eyes and your prescription changes, you will once again need corrective lenses.  To my thinking, correcting a multifocal lens with a progressive lens creates an exponential increase in the spectrum of vision along which you will need adjustments, with a narrower margin for error and a correspondingly greater chance for screwing something up.

Bottom line imo:  monovision = fewer variables = lower risk of complications.
