Adjusting to Trifocal - Neural Adaptation?

Eye care
1

I’m just over 6 weeks post surgery. I had a Vivity EDOF lens implanted in my left (dominant) eye and Panoptix trifocal lens in my right eye. Overall the recovery has gone smoothly and I have pretty good vision now for close up, intermediate and distance - so pretty happy.

The mix and match approach seems to work well - I have good vision from about 20 cm to infinity. The one drawback is that I am struggling though in low light / challenging light conditions. The eye with a Panoptix lens seems to go blurry from time to time, most noticeably at the end of the day when I’m feeling tired. This makes night time driving a little more difficult.

My Panoptix eye in these instances gives blurry vision, but clear halos.

If I close my right eye and use my left, the Vivity lens works well but if use both eyes, things can get a little hazy. I can still see fine, but it’s just not perfect.

On Friday I had a 6 week check up with my surgeon. He did a thorough eye test and everything is bang on - no refractive error which is great. The blurriness he puts down to be Neural Adaptation - my brain needs more time to figure out which image on my retina to use. This will come with time. He’s asked me to return in 6 months.

Anyone else had this issue with a Panoptix/Multifocal, and how long did it take to resolve?

Other than just getting on with life, is there anything that I can do to accelerate Neural Adaptation?

i experience this late at night after 10-11PM when it gets dark. correcting for astigmatism and mild myopia (not detected during day) makes vision better.

What about first thing in the morning? From what I can see, my vision is worse at night when i’m also tired. Have things improved for you over time?

i m only 7 weeks out. upon waking up the distance vision isnt great but in 10-15 mins all distances are good. i think things have been steady for last 2 weeks. i have about 0.75 astigmatism which hurts the night vision.

It could also be dry eye. Try some good quality moisterising eye drops when you feel tired (decreased vision) and see if it makes a difference for you.

As far as neuro-adaptation, I personally dont believe there is such a thing. I think it’s dr’s way of saying: take a walk for a few months and hopefully you ll just submit to your current reality before you start bugging me again about things I have no control over. It’s like when you get a ding on your new car. It bothers you lots at first, but after a few weeks, you just forget it and live with it even though your “brain” knows the ding is still there!

Not my words, but an ophthalmologist words. I just paraphrased with my soon to expire artistic license.
