Flickering light after cataract surgery

Posted , 20 users are following.

I have seen a few discussions about this, but I was wondering...of those who saw this subside, how long did it take? Days, weeks, months? I have had surgery on both eyes, but only see the flickering in the left. It's been 4 weeks, and it is slightly better, but only slightly. Just wondering how long I should give myself to adjust?  Thanks

    Andrew:

    Can you give a more detailed description of what you are experiencing?

      I have heard some people describe it as though a fan were above their head rotating around. That is close to what I see. It's definitely coming from the left side of the left lens. It's not flashes of light but rather just a flickering. Almost like looking through a coke bottle for a moment. Interestingly to me, I don't notice it as much if I close my right eye. Also, it is associated with eye movement. If I keep my eye focused on a single point, it goes away completely. It started the first day after my surgery. The left eye is using a Bauch & Lomb Envista MX60E IOL. The right eye was done 2 weeks later, but does not have the same type lens nor does it have that distortion.

      Some lenses have round edge that do not have that issue with edge glare but you are more prone to get PCO.  Square edge IOLs tend to prevent PCO better but have that edge glare.

    It becomes less noticeable over time but I still notice it in certain light conditions - particularly, if the light is coming in from the side (refraction off the hard edge of the lens).  I was told that the brain will adjust but ......

    Was going to ask same question as Derek.  

    Is it a streak of light that is noticeable only with the eyes open and exposed to light? This is common and usually related to reflections off the implant after cataract surgery.  But flashing lights that are seen in the dark or with the eyes closed are a different matter.

      Sue.An I have the light flash when I turn my head from right to left ,in my right eye,it's now 9 weeks since I had the left eye done.I see it in the dark,I was a little concerned about a retina detachment ,but after geting it checked out by two different optometrists,they told me the retina was fine. As for how long I will see the black shadow/rim and flashing light,the surgeon told me it should go away within 4 months,it's now over 2 months with no change,and I I just had YAG performed on my right eye ,the first couple of days it appeared to be some what clearer,but now at times it's still blurry and I see double vision.Before having both eyes done I could see much better with the cataracts using my reading glasses than what I can see now.

      Freeman62151 did you have the double vision before the YAG too?  I had double vision due to cataracts but it was corrected with the cataract surgery.   That light on the peripheral vision occurred only if a light source was a certain angle - left side (never experienced it on right side) but it is rare I notice it anymore (I am 12 months from 1st surgery now.

      Good you had the retina checked out to confirm it wasn’t detached.

      I definitely believe it is due to the light striking the edge of the  lens. It does not happen with my eyes closed. It happens mainly with light that is coming from the left, but is the most noticeable under fluorescent lighting (in my case, at work).

    Flashing light like a police car behind you can be sign of retina detachment.  So take it seriously and see a doctor asap.  Retina detachment is a medical emergency.

      20/60.  It was 20/100 prior to surgery.  But I find that deceiving. When I read those “lower” lines, I may be able to see the letters, but I can’t always be sure  where they are in comparison to each other but I still get credit.

      I know exactly what you are talking about. 2017 was a terrible year for vision fr my family. My 10 year daughter was diagnosed with amblyopia in March and me with cataracts in August. Her Amblyopia went undetected as we were out of US for few years for my work and she didn't notice nor was there a vision test requirement in school. She did not have a squint. 

      After an year long therapy to restore vision they says she is at 20/30. Improvement from 20/400. But as the line get smaller she is all jumbled up just like you say and they give her credit for that. She has still not patched her eye. 

      We will begin patching over the next two months in an attempt to get her to 20/25 or better. 

      I inherited early cataract from my mother. And if she inherits from me then she is in amblyopia plus cataract boat.

      Wow Soks - sorry to hear that.  You’ve all been through (and still going through a tough year).   Hopefully your daughter is doing better in school.   I remember when my daughter was 2 she had lots of issues with ear infections/hearing - saw a specialist every 6 weeks.  Finally grew out of it by age 5.  Also due to her being left handed she had to go every 6 months to test vision (apparently a link between being left handed and dyxlesia. ) Since at that age there is no letter recognition they put an E on the screen in each direction and ask the child to mimic what direction the E went with their hand.   

      Interesting to note though that Symfony does mix fine with a monofocal.   I know when I was asking surgeon when I had just one eye done it wasn’t encouraged to mix IOLs.

      Very sorry to hear this. It has been difficult for you. I hope your daughter works with you with the patching. I only have the slightest memory of my parents trying to get me to use a patch. I think I was maybe 3 or 4, but they did not force me as they needed to. Stay on her about the patching.
