Clinical research of accommodating intraocular lens warning signs of dating abiuse

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.At near my vision was already about 20/25 (but fluctuating a bit it had seemed better earlier that day).Given its improvement since then I'd guess its likely 20/20 or so, I can read the small print on my eye drop bottles for instance.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.

Contact lens powers are a bit different since the lens is at a different distance from your eye, so a conversion chart shows a -8.25D glass prescription is about a -7.75D contact lens prescription.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....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.

My intermediate vision hasn't been tested explicitly but I suspect is at least 20/20.
