Not everyone achieves this level of near vision with the lens so people shouldn't expect to necessarily get quite as good a result, and should be prepared for the possibility for needing reading glasses at near.I suspect the fact that I'm comparatively young for cataract surgery, 52, might have something to do with the results.Regardless it may give you some idea of whether you can adapt to a difference between the eyes (though if you struggle it may be due to the cataract).Again the level of near vision you have will be more than with a monofocal IOL since even your distance eye can focus a bit near still at your age.
So, it looks like they are having their cake and eating it too.” I had considered the option of getting a trifocal lens which targets far, intermediate, and near (also unfortunately not yet available in the US), or even a bifocal with a small add so its focused more at intermediate than near.
That may be in part because as it notes: ' "Pushing” does not equal “Sustaining” '.
This issue is that someone with their natural lens still who is presbyopic for instance may be able to theoretically read a particular print size without glasses, but that the muscle effort to focus may be a strain to do for an extended period of time, and the Crystalens at least partly seems to require the same sort of accommodative effort.
I had originally only planned on having 1 eye done (since the other was 20/20 correctible still), but when the patch came off the next day I discovered it might be hard to adapt to the difference in vision between the two eyes even with a contact lens in the other eye.
I might have quickly adapted if I'd taken the time, but I decided I didn't want to risk it, so I had the 2nd eye operated on a few hours later.
