There is no perfect lens, so its partly a matter of placing a bet on which might work out well, and I figured that it was better to bet on something that didn't require the accommodation to work (in addition to other concerns regarding problems people have with the Crystalens, though those may be fewer in the newest versions).
I hadn't searched to find the study behind the figure in this presentation, but it notes: that about half of Crystalens patients require reading correction.
Most household tasks and social interactions occur at intermediate distance as well.
Unfortunately the lens isn't yet available in the US yet, they are starting a clinical trial here which is randomized with a monofocal lens (there is a 50% chance you would get a monofocal) so I went to Europe for my surgery.
page=0,1 "the Symfony IOL might be available in the US by late 2016 or early 2017... from what I’ve heard so far from respected and trusted surgeons, patients implanted with this IOL are seeing 20/20 at distance and intermediate with very usable, J2 or J3 near vision and are not experiencing any loss of contrast or perceptible problems with glare, halos or other dysphotopsias.
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.
I spend a large number of hours at a computer and was willing to risk needing reading glasses occasionally for near in order to get better intermediate vision.I figured that at my age I hopefully may be using these lenses for a few decades so it was worth a bit of effort to get a better lens.This industry publication suggests it might be generally available in the US in a couple of years, and that some US surgeons find it interesting: Packer concurred that the brand new Tecnis Symfony Extended Range of Vision IOL was the most interesting as it represents a new concept for addressing presbyopia that seems to overcome the limitations of multifocal IOLs....My intermediate vision hasn't been tested explicitly but I suspect is at least 20/20.That is based on my subjective sense of it being better than near and because of the design of this lens where visual acuity drops off in a continuous curve from far to near, so intermediate should be around the same as far, definitely better then near.
