Symfony IOL - 6 days post op & night vision problems

[harveebee]

I'm now 6 days post op, had the Symfony IOL implanted in my right eye, procedure was done with the Victus Femtosecond Laser.  For about 2-3 days after surgery I had quite a bit of discomfort i.e. scratchy, bloodshot eye, felt like I had sand in there but that's pretty much gone now. I can now read a newspaper at about 12-16" and everything is brighter, whiter with my right eye, especially compared to the left. I realize it's only 6 days post op but my biggest concern is that at night I am seeing significant halos and blur/glare around points of light such as headlights, streetlights, etc. There are also concentric circles in the blur around the lights and I am guessing this is from the diffractive optics of the IOL. This is quite concerning and I am hoping this will go away over time. Has anyone had the same experience and if so did the night vision improve and how long did it take?

Studies on IOLs tend to only report the frequency of halos at 3 months or 6 months after surgery because even with monofocals halos are more common during the initial postop period while the eye is still healing. Most of those who see halos during that period see them subside. Even after 6 months, many who do see halos will still eventually see them go away as they neuroadapt.  

A certain percentage of people even  with monofocals will continue to see halos.  there isn't a lens yet that is free of the issue, but most people see them subside.  The studies on the Symfony show the % of people with problem halos tends to be comparable to those with a monofocal (perhaps not quite as low as the best monofocal, but better than some monofocals).

I'm one of the rare minority that continue to see halos with the Symfony, but I don't consider them a problem since they are mild and translucent, I see through/past them. My night vision overall is better than I can remember it being even before I had the cataract, which more than makes up for it.  As one surgeon posted on his blog after a year of implanting the Symfony:

"What about halos?
Some patients, when asked, did describe mild halos around lights at night (such as car headlamps or traffic lights) but were not troubled by these halos. One patient even called it pretty!

The distinguishing feature of Symfony related halos (mentioned by 18% of my patients) seemed to be that they were quite mild/light, and patients were able to see through the halos.

Personal thoughts
There is still no perfect solution for presbyopia as yet. However, I think for myself, the Tecnis Symfony is one of the best compromises out there at the moment.
