near vision poor after getting Symfony...seeking others' experience

Posted , 66 users are following.

Hi,

I'm 44 years old and just had the first of two eyes implanted with the new (I'm in the U.S.) Symfony Toric lens, which I've researched extensively and was very eager and excited to get.

Now four days since having the surgery, I'm mostly satisfied: colors are much brighter and more vibrant (and more pinkish, bluish, interestingly), my distance vision is now restored and fine, and I can see pretty well at intermediate distances, i.e. objects are clearly defined all the way in to about 23 inches away, perhaps even 21 inches away in bright light (yes, I notice some degradation in low light, more than I'd expected).

The real issue for me is my near vision, which is much worse than I was expecting. I do know that the Symfony isn't all-around perfect, that e.g. I might expect only 20/32 or so (mean uncorrected near achieved in the U.S. clinical trials). And I know that's just an average, but even the distributions left me hopeful, with 81% of trials patients achieving 20/40 or better (that's monofocally; 96% were better than 20/40 bifocally). Meanwhile, I'm struggling to make out these words as I type, pretty much anything inside of 23 inches is blurry, and in good light I can only make out the 20/80 line (if I really exert myself, I can barely make out, mostly by guessing, some of the 20/60 letters, but mostly they're entirely unrecognizable). I feel as if I could have gotten results like this simply by going with monofocals, and I'm beginning to fear this is as good as it'll get, which is depressing.

Some background facts: Pre-op, I was mildly myopic (-1.75) in this eye and mildly astigmatic (about 0.94 cylinder). Also, at 44 I'd already gotten used to presbyopia, and typically would wear +1.25 readers for near. The specific lens implanted was the ZXT150 +16.5 (1.5 D cylinder). I doubt lens alignment is off, as my distance and intermediate vision feels non-astigmatic. My other eye (right) is scheduled for another Symfony lens 10 days from now.

So, I wonder:

1) Have others had similar experiences, i.e. poorer than expected near vision?

2) Does anyone have any idea what might have caused this?

3) Can anything be done to correct it?

4) If anything can be done, should I expect my ophthalmologist to do it (without having to pay more than the significant amount I've already paid)?

Thanks for any info and advice!

    I've also been having issues with glare, starburst and halos at night. Driving and reading signage is difficult. Now that I'm 6 months post op, I can have the YAG laser which should help with all the above. They would not approve YAG earlier due to risk of causing a detatched retina. One eye is done at a time, one week apart. Will update here after the procedures in December.

    Here’s a scary update.  For 1 1/2 weeks after surgery I had near perfect vision 20/20 in all ranges.  Then my lens rotated almost 20 degrees. Had to go back into the OR and have it rotated back.  Within a few hours it moved again. Further this time.  Plus I had darker vision. Really scary. I slept one night and it had rotated back again. Although the contrast didn’t come back as well.  Doctor says that pupil drops constricted the pupil causing the darker colors.  Says she can put in a left handed CTR to try and stabilize the IOL.  At this point I’m not sure and going for a second opinion by parking myself in the ER at Mass Eye and Ear.  Very concerned.  More surgery necessary to stabilize this rotating lens.

      My Symfony toric lens had also rotated about 20 degrees which resulted in Astigmatism. My surgeon gave me the option of having it rotated back to the correct position or having the vision corrected with LASIK by him. Both of those options were free for me. I chose to have the LASIK correction because I was concerned that the lens may rotate again, as seems to have happened in your case. You still have the option of having the LASIK enhancement done after the lens stabilizes in the new position in 3-4 weeks.

    Im very interested in your post  I don’t know the technicalities you sited, however, I have this experience to offer.  I had my left eye implanted with Symfony lenses on 1 Nov,and have excellent vision in all ranges, up to about 12 to 14 inches from my face, which is what the doctor said I could expect.  Had my right eye done on 8 Nov and have 20/50 vision on day 7 from surgery. I can’t even read a road sign.  Distant vision is the worst.  I have fairly good vision watching TV.  So, in answe to your question 1, I have poorer than expected far vision, and would love answers to your questions 2, 3, and 4.

      How is your close vision with the right eye? It is possible that  that your surgeon did a terrible job of figuring out the lens prescription for use in your right eye.  The only way to confirm that will be to get your eyes checked to get the needed prescription for distance and to know what your best corrected vision is.

      Both near and far vision are bad.  I am thinking it is either wrong prescription, or problems with eye drops.  I just have bad vision at all ranges in the right eye.  Thanks for your response.

      Has your vision varied in the right eye over the past week or so?  Its still relatively soon after the surgery, since healing takes 1month+

      I had cataract surgery Oct 24 with a tecnis monofocal toric IOL, so its 3 1/2 weeks for me and my vision has varied quite a bit over that time.  The day after it was around 20/40 and improved at times a week later to as good as 20/25 and nearly 20/20 for periods, but unfortunately for the past week or so its gone back to 20/40 to 20/50 most of the time so it might be stabilizing there instead of the better vision it was capable of for a few days a couple weeks ago. 

      I believe the eye has gotten a little nearsighted and probably some resididual astigmatism too. I have an optometrist appointment next Wed so I'll see exactly where its at then and hopefully at least it can be corrected to near 20/20 with glasses.  Hoping for glasses free doesn't always end up the result with the variables of cataract surgery - they can't perfectly predict how the cornea will end up after cutting into it.

      Hi Hawk - wondering if the ORA during your surgery had any bearing on where lens winds up.  I was hoping under the impression ORA assisted the surgeon to get best correction but maybe I am wrong and as the lens fixes into place weeks after surgery accounts for more or less the vision one ends up with.
    • Posted

      In theory the ORA equipment should allow the surgeon to verify the refraction result during surgery without it just have to hope his calculations end up close.  Though the cornea could change thru the healing process after the incision, so the results can still be off weeks later, even with the best pre-op calculations and ORA.

      In my case, I believe the power is not too far off but perhaps too much residual astigmatism. Won't know for sure until an optometrist can test if the eye can be corrected well with lenses and what the Rx ends up.

      Unfortunately my right eye is the most blurry its been the last couple days and getting close to one month after surgery.  I estimate today its definitely worse than 20/50 probably 20/80+ and now as bad as it was pre surgery corrected with the cataract.  Its possible the toric IOL has rotated, or one of the possible swelling issues or early PCO.  So I I'll probably have to try to get a full dilated exam sooner than my schedule early Jan appointment if it doesn't get better soon or at least able to be corrected well with eyeglasses assuming the Rx will be stable.

      It will be a good idea to have an eye examination very soon to check if the toric lens has rotated significantly from the angle at which it was installed. The longer you wait, the harder it will become for the surgeon to rotate it back to the correct position.

      You must be disappointed.  I am still hoping something can be done to give you better vision.  I suppose if lens has rotated the surgeon can rotate it back or maybe do lasik to correct.  

      Think you should contact the surgeon’s office to see if he could see you sooner.

      Well today my right eye vision came back to near the best its been.

      Seems to vary by a bigger jump day to day, and then stays within the day (even over several minutes) within about 2 lines on the eye chart.

      However days like today where in the morning my right eye had a nice clear image of the eye chart 20/25 line, at times blurring/fading slightly to 20/30 and sharpening at times to nearly making out the 20/20 line - I would have to say the toric IOL must be close to the right position to do that at all.

      I would expect if the toric IOL rotated signficantly, the vision wouldn't get better the next day, I haven't heard reports of it rotating off one day and back the next - they tend to rotate within the first month typically and stay at the new position.

      So the vision variation I've been experiencing day to day, and the lesser variation within a day, must be due to some other cause.  Possibly the cause is not even related to the cataract surgery, since I seem to recall I had vision variation year ago before the cataract started to affect my vision in that eye.  After the cataract made the eye really blurry, I wouldn't have noticed the variation since it was just too blurry, so I made just be able to notice it now after the catarct is now gone.

      So at least I feel better that its most likely not due to toric IOL rotation, that would require going thru the whole surgery procedure again (incision so they can grab and rotate the IOL back) and all the healing and eyedrops over again.  I will just be patient and hopefully after more healing it improves and perhaps the eye doctor can check for any other possible causes in my right eye at the scheduled full dilated comprehensive eye exam in early Jan.

      I also have the eye exam at an optometrist this coming Wed, and she might be able to check the cornea and retina condition (make sure no significant swelling, etc)  as well as get the refraction result for my right eye.  At home I've found a small -0.25D or -0.50D eyeglasses lens helps get me at least one line improvement, which makes sense since that eye's target was -0.25D and there is always up to 0.50D error possible, plus there is probably a little residual astigmatism (0.50D typical) that corrected with eyeglasses could give yet another line improvement.  So if I'm getting 20/25-20/40 range like today uncorrected in that eye, 20/20 is possible corrected it would seem.  I will find out on Wed.

      Today I found an excellent online webpage eye chart that has a calibration line that you measure in centimeters and then stand back from your computer monitor to view it by that number of feet.  For example, on my 24" monitor the line measured as 6.5cm, so to view it I measured 6.5feet.  I stood back that far and could read the lines and could read the 20/30 line uncorrected.  The next lower line was 20/20 and with -0.25D eyeglass correction I could read most of the letters on that line.

      I think this is a better controlled eyechart test since it doesn't depend on room lighting which varies with a paper eye chart during the day with windows in the room, etc.  Much more repeatable from my experience.

      Here is the website address for this eyechart, I left some spaces that should be removed. Hope it works to display here:

      Should find an excellent online eye chart viewable directly on a computer monitor. There is a calibration line that on my 24" monitor measures 6.5cm and then you view if from that many feet away, in my case 6.5feet from the monitor.  Gives a good repeatable viewing that isn't dependent on room lighting conditions (windows, etc) like with a paper chart on a wall.

      With this computer displayed eye chart, right now I can read the 20/30 line uncorrected with my right eye, and the next lower one is the 20/20 line, and I can read most of that line with a -0.25D eyeglass lens.

      Wow really a roller coaster ride up and down.  But likely indicates iol didn’t rotate.  I wonder if eye charts can be purchased anywhere?  I have used my computer too to test.   Now I am curious for my  optometrist appointment dec 1 to see where I am.

      I see you can buy the standard Snellen eye chart (viewable from 20feet away) at amazon and ebay for under $10. Just do a search for "Snellen eye chart" there.

      There is also some smaller versions of the chart available for sale as well, viewable from a closer distance like 6feet or less. But for a good distance vision test I would think you wouldn't want too small of a one since then you might be more testing intermediate distance.

      On a side note, I'm also noticing my right eye is also giving better uncorrected computer distance vision today, at about 2.5feet away from the monitor. I'm using my old computer vision eyeglasses with the right lens removed, so the left eye is doing most of the work, but the right eye vision is now actually useable at that distance whereas previous weeks its been more blurry at that distance.

      Thanks will look for an eye chart.  It is good to test - not sure if ever there will come a time I just don’t think about my eyes or vision.  Certainly take nothing for granted.  I am actually looking forward to optometrist visit to see if I can get a baseline to where I am.

      Awfully rainy here today- first time driving at night in rain - not too bad - better than I anticipated.

      That should find the website with computer monitor viewable eye chart with instructions.

      Found it.  Find the lettering on the chart a bit smudged.  With right eye can read most of the 20/20 line and left eye can read most of 20/30 line.   Would like to find a clearer chart.  When I see the optometrist Dec 1 I will have an accurate test.
