I would echo the comments of the two previous posters. I recently had cataract surgery, and also opted for "modified monovision" — an implant for distance in my dominant eye and one that left me slightly nearsighted (but still able to pass the vision test to renew my driver's license in the state where I live) in my non-dominant eye.
Some acclimatization typically is necessary to get your brain to sort out the two slightly different refractions. After the surgery on the dominant eye, my cataract surgeon fitted me with a contact lens in the non-dominant one that mimicked the refraction she intended to use for that eye. I used the three weeks between the two surgeries to verify that this was a workable solution for me.
My wife, who was born with monovision and whose presbyopia isn't as advanced as mine, doesn't need to wear glasses for either distance or reading. However, the surgeon told me the delta necessary for that would almost certainly be too great for me to adapt to, so we settled on a metric of being able to drive without glasses and still be able to make out the controls on the dashboard of a car.
It has worked out even better than I expected. I have pushed back both monitors on my desktop computer a few inches and I can process photographs without putting on my inexpensive, non-prescription reading glasses. I can even read small type on a laptop without glasses as long as I'm willing to put up with a little blurriness; I'm typing this post now on a laptop that is sitting on my knees.
And—this turns out to be
very important—I can see the physical controls and menus on my cameras without pulling the reading glasses out of my pocket. (Thanks to Craig Lamson for his comments alerting me to this issue, which he sent me in a couple of private messages on this site prior to my surgeries.)
Neither my regular ophthalmologist nor the cataract surgeon offered me the option of blue-filtering intraocular lenses, but there is what appears to be
a fairly thorough review of the literature on the subject here. It's my understanding that all current intraocular implants filter ultraviolet to some extent.
