Accommodating iol

That is one of the differences between this lens and for instance a bifocal IOL where vision may be worse at intermediate than it is at near or far.

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.

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.

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.

It is a new type of "extended depth of focus" lens that uses a different design than multifocal and accommodating lenses.

The other thing the Symfony does is to correct for "chromatic aberration", an issue which is discussed in this industry publication which quotes one prominent surgeon noting: Cataract surgery with an IOL with an Abbe number greater than that of the natural lens (47) can improve CA, so that our cataract patients could actually experience better vision quality than they did as young adults.

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.

So according to those values, the contacts did give leave that eye around -1.75D myopic (the value at the spectacle plane isn't much different).

Refractions aren't exact, and can fluctuate throughout the day and I don't know if your glasses RX wasn't from this optometrist but your doctor perhaps, so I'm suspecting the optometrist gave you -1.5D monovision according to his measurements when you got them.

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.
