Clinical research of accommodating intraocular lens

However the studies so far seem to indicate that the Symfony provides better quality intermediate vision.

In addition multifocal lenses reduce contrast sensitivity which is useful for night vision, while reports indicate the Symfony is at least as good as a monofocal lens.

It seemed like a good bet the image quality for distance would be comparable, and perhaps even better, than a monofocal lens, or an accommodating lens.

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.

I had Symfony lenses implanted in both eyes the first week of December.

By 1 week postop my uncorrected vision at distance was between 20/15 and 20/20.

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.

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....

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.

I'd posted before asking for information about lens options before surgery, but thought I'd start a new thread now that I've gotten the lens where perhaps others can add their results as well with the Symfony lens.
