YAG or re-implant for negative disphotopsia

[icpatterns]

I have very noticeable negative disphotopsia in my left eye after cataract surgery three months ago. I had a nanoFLEX collamer lens implanted. Supposedly the lens is in the correct position according to three different doctors I have consulted. My right side implant (same make and model) has no issues.

My original surgeon wants to do a YAG to fix the issue. The thought being there may be fluid in the capsular bag behind the lens causing the visual disturbances. A different doctor told me replacement is better because the new lens is placed in the sulcus, closer to the pupil, so seeing the edge of the implant is less likely. My original doctor says if I still see what I perceive as the edge of the implant even in a brightly lit room, then I am not seeing the edge of the implant because the pupil had been made so much smaller due to the light and no light should be hitting the implant edges with my pupil so small. Both arguments make sense.

I am concerned about doing the YAG because it seems to take away the option of lens exchange if the YAG doesn't work. Once that vitreous fluid comes forward after the YAG, an exchange surgery has more chance of complications.

I am equally concerned about a lens exchange - having my eye cut on again, the possibility of iris chafing and still needing a YAG later anyway.

Has anyone here had negative disphotopsia and had it solved by either YAG or re-implantation?

Thanks!

I too have negative dysphotopsia and even a touch of remaining positive dysphotopsia in my right eye that was implanted with an Alcon lens almost 9 months ago!  The edge glare shimmering off bright light sources seems to have gotten a little better, but the dark crescent is still there. I also get a flickering (strobe) effect when moving that eye around. I am so discouraged, as my doctor had nothing to say about it, and now there is question about doing the left eye (the better vision eye) since there has been no resolution on the right eye problem. I have nowhere to turn and am stuck with this seemingly permanent very distressing vision problem - for which all my research has not revealed any answers as to cause or resolution..

The lens exchange would be much more risky now without an intact capsular bag. I assume on my next visit they'll tell me to wait and hope the visual anomalies go away. I'll probably give it six months and see if I need to seek out another opinion.

Sorry to hear the Yag laser didn't work.

I'm still debating about having the lens exchange done but I'm scared to take the chance (better the devil I know than the one I don't).  Are you still considering the lens exchange?

Negative dysphotopsia (I spelled it wrong initially) is where you see the edge of the implant like a dark crescent in your peripheral vision. It is not well understood how to treat it or what causes it from what I can tell based on various second opinions I've sought out and internet research.

I had the YAG laser done a few days ago and still have the same issue. I have the same lens in the other eye with no issues. The type of lens I have implanted is supposedly one of the best for NOT causing this problem.

What is "negative disphotopsia"?  I had cataract surgery four months ago & am considering a lens exchange for other reasons.  Please see my postings on 6/30/14 & 7/21/14.  Sounds like you've researched as much as I have.  I Would appreciate your comments.  Thanks "eyecry"
